No AC rated motor can run on straight DC without some form of commutation. Which means this particular one must be a brushed, AC/DC universal motor. Also, a raw potentiometer placed in series with the power source, for use as a speed control will be cooked once an actual load is applied to the shaft.
@@Cey-001 Potentiometers are low current devices normally intended to be used in circuitry that controls the output of other components that ARE designed for high current, like transistors. The position of a potentiometer should adjust the speed of an oscillator, PWM timing or some other parameter in a secondary circuit that actually drives the load. Which, yes, that's the basics of how an inverter works. Additionally, _true_ AC motors are brushless, inductive devices that require AC to operate. The one shown in the video is a special class of motor, called a "universal" motor that has brushes and can run on AC or DC. I.e., _most_ motors labeled as "AC" cannot, and will not, run on DC.
12 volt motor + battery= almost endless uses "off grid" remote locations , camper van fun, propulsion. ...12v a lot safer than 240! Great video and instruction, looking forward your next one, thankyou!
there are downsides of using DC vs AC, I'm sure you know but I will just mention the thickness of the wires, DC requires much thicker wires as it carries higher current ie AMPs, granted he demoed that motor with thin wires but there was also no load on the motor, there is no way that motor spins your wet laundry using only 12 volts without automotive jumper cables as it needs to make up the power somewhere and so it needs to pull them AMPs (AC is high voltage so 220 but low current, I think on the motor it said 1,6 AMPs)

using that same concept if you charge the rotor windings with 12V dc, u can use the stator output then as a generator, and once the motor is at speed u can use the stator output to keep the rotor charged as long as you keep the motor turning...... I have done this with a 30KW 3phase electric brush motor. Works like a charm. Built myself a 3 phase generator with a 1400cc petrol engine running it.. and that will give you an 220v output.. on your motor...
Motor nameplate says 230-240v, 1.8A, 350W - (1/2 Hp Rated Load) which should be at (1.0 Service Factor). 12VDC will turn it, but do not expect any sort of power output (not even a fan), as the battery would need to provide 29 Amps to run fully, and possibly burn out the winding as it is rated at 1.8 Amps. The operating volts required suggest that this is from England.
In this configuration there would be only a little usable power. If however you connect the field winding across the two brushes (in parallel) and the apply 12 v also across the brushes, even though the speed will be slower than the rated output, the torque should be much higher. Experiment with the wiring of the field coils (if there is more than one) for the optimum performance.
Thanks for the info. Yes I understand that other configurations could be considered. The point of this video is to show that a 240VAC motor will operate at 12VDC. The applications we would leave up to the viewer. Thanks
I wired my 240v AC motor through a 1000w inverter powered by a 12v car battery, a few cogs and chains later, and my barrow was powered by motor. Because of the 12V input the torque suffers but it moves freely with a little weight in it, and that is all I wanted.
Very interesting, how efficient is the motor when running off 12v, and how is the motor torque affected? Does this mean also that you could use this same setup to generate 12v as a generator of a small wind turbine?
Induction motors that depend on line alternations for commutation are a common scrapyard treasure in the U.S. from old washers. Best to avoid those unless an inverter is planned.

That's a high torque motor driven on high voltage. If you cut the voltage in half you reduce the torque down to 25% of the original designed torque. Some AC motors can be run on DC because they use coils for magnetic fields, both on the stator and on the rotor. With a brushed motor such as this, when the AC is moving - lets say left - the motor spins - again, lets say - clockwise. When the AC right the magnetic poles reverse WITH the AC, making the motor continue to run clockwise. Whether the current changes or remains steady the motor spins. When spun on its designed voltage it can be quite powerful. But when you reduce the voltage you reduce the power by a factor of four. Inverse square law applies. A 1 inch square has one square inch, whereas a 2 inch square has four square inches in it. Inverse square law explained in simple terms.
You and some of the other polite commentators are adding useful information here. I collected some motors, hoping to understand their potential for projects one day.
Sir Im wondering wuld car alternator with singel winding coil turn as dc motor if you for exampel put round magnets in the in side and out side on that same rotating shaft?I mean the are round but those magnets are stationary . Wuld that rotor turn to by dc motor? I was wondering what wuld hapen if you put pm magnets with rotor coil wuld the magnets stop working canceling ich other out if they are aranged in centrain polarity? Just wondering what wuld hapen if you use oposing poles ore just atracting poles? That got my curiuse.
The are several videos on this platform showing a conversion from alternator to dc motor. Some are not very easy to follow. We will be looking into this in the future with a view to doing a diy simple cost effective conversion
Ok like the video, but can you connect another motor to output 12V to power a battery charge and then run a 12V bulb from it, this would prevent your battery from running flat and power a light?
nice for a paint mixer but thats it... it runs at a tenth of the rpm so i suppose if it was a 300W motor it will probably now be a 30W ... hmmm very good info there anyways and a great clean and good understandable video :)
I need to use this motor wirh little load for short durations as 20mins max . Can a Dc motor speed controller of upto 10 amps be used where potentiometer is used . ? Or that controllee isnt good for here
It's not permanently hardwired. We used a couple of spade connectors so at any time it can still be used AC. With DC it can be more versatile and portable
@@DrivewayDudesrunning this universal motor on dc current does it give u high torque becoz i using this motor for e bike by connecting 24v batteries in series to get 72v is it enough for motor run at high torque plzz reply
@@DrivewayDudes thanks, I am learning so apologies for asking all the questions, now why can't we get the spin speed from the higher amps of the DC batteries, I mean isn't power power (v x a = w)? ha ha
@@Good-Enuff-Garage as an example: 2 x 12V 7Ah batteries connected in Series would be 24V and 7Ah. In Parallel voltage remains the same at 12V and amps doubles to 14Ah so 20 x 12V 7Ah batteries connected in Series would be 240V 7Ah and the same amount connected in Parallel would be 12V 140Ah
The last washing machine I pulled apart used a 3 phase induction motor, with a variable frequency drive. All previous were single phase induction motors. Where are you that they use brushed motors?
i pulled apart "millions" of machines while working for a recycling company, around 50 per day and the machines manufacturers used solid rotor induction motors up until 15 to 20 years ago,back in the day the motor start capacitor was a big failure point...... then they switched to brushed motors up until 2010 more or less bringing the top failure point to the wear of the brushes... the majority of the washers still around are brushed motors atleast in europe. cheap washers still use brushed motors...most modern big capacity ones now are direct drive and dont use brushes. those motors seem very reliable but they fail due to tachometer failures and control modules are also very failure prone
@@das250250 on brushed motors the tachometer is a copper coil at the back of the motor and inside of it its a cylindrical magnet ..that provides motor rpm info to the washer machine control board.. the more rpms the more voltage is generated at that coil...usually it has 2 thin red or yellow wires coming off of it... on direct drive systems sometimes there is a hall effect sensor like in 90's car ignition systems but other approaches may be used..i havent taken apart many direct drive machines, and the one i have worked on are mostly "LG"brand, and i can only speak for european market machines.... if you want to check my channel i do appliances repair and vintage vacuum tube equipment restoration
The other type of motor used, are single phase induction, cap start, reversible. One direction runs the agitator in the washer, and reverse brings up fast spin cycle - function is through the transmission based on direction (GE basic top load ca 1990's)
Important things to know. Max current? Ratet current? Continuos current? If use 12 volt 20 ampere, how many rpm will get? And then check the motor, it's hot or not?
Hello sir are you familiar with baterry de sulfation usein 1 dead baterry 1 fully charged and 1 dc motor? Some peopel did done it suposedly because they did not have baterry charger so any usefull info about it? Suposedly it culd work with transformer/baterry/dc motor as well so that cinde of got me curiuse .
You can connect a good battery to a dead battery in parallel which may partially charge it if it is not beyond recovery. Running a motor using both may drain the good battery quicker
@@DrivewayDudes well thank you for response I have strange projects so I was wondering culd I cutt windings in half on starter motors field winding ore if it is magnetic starter motor to cutt out 2 brushes from the 4 brush holder Im looking for those old sg's ore compound motor/generator patents but cant finde any thing usefull about it . Aperanly delco hade 4 commitator brush starter/generators ore those were some rotary inverters/converters/transformers so I was wondering do you know some thing about those old designs how they worked and how to coppy them? Well to be honest Im surching for alternative methodes to run me ignition coil so I was wondering if I culd some how modify me starter ore alternator to act cinde of those old dynamos if me ignition coil for some reason get fried I wuld like to have back up plan some sort of . I have constant problems geting voltage to me ignition coil who is E core type hei with 4 pin gm ignition module I have that starter motor r terminal bypass wire but it aperantly works only at points not on hei so any ideas where I can draw curent directly to me ignition coil? Me alternator is old delco 12 si it has that odd bypass pins for rotor so I was wondering can I draw curent from there and use capacitor in series with me ignition coil wuld that work? At this stage I dont realy care If I fry some thing I just need some back up plan to solve low voltage. I did try out plasma ignition first it was nice faster spining starter motor ,bether smuther engine but I come acros problem me starting charge rpm from 1200 goes up to 2500rpm thats when I use hv capacitor to coil + and simply ground out capacitor other side to chassis . So I have cinde of problem with me reference voltage to me baterry so any ideas how this problem can be solved??? I have multipel of those old gm parts so I was just wondering how I can bypass dashboard some how I have voltage regulator inside that thing its anoying so I was also wondeing if I culd stuff up some nails in me starter selenoid and wind that thing in series ore pararel with me E core type ignition coil but Im afraid to fry some thing . So please any thing you know that might help me with me unusual problems? I experianced lot unusual things with me alternator similar to plasma ignition was failing voltage regulator gived me similar effects but it fryed baterry so that also made me wonder can I use capacitor banks and drive just me ignition coil with ac and how wuld I prevent me baterry to get fried?
@@MechanicForGMCCars Schottky diodes allow voltage to travel one direction only. Capacitors can be helpful if you are familiar with them or they can be dangerous to very dangerous if used incorrectly. Gate transistors can also be useful. And of course fuses can save your equipment in the case of voltage surges
@@DrivewayDudes well to tell the truth have no realy money so I cinde of must steel staff like canibiliseing me pore mothers micro wave oven . So I cinde of have plenty hv capacitors hv diodes some rectifier diodes I do have some old psu from computers lot small electronic devices scavanged over the years . But still Im not so shure to fumeling with any thing. I did was some what curiuse to fumel with alternator and I noticed that thing is cinde of going to baterry negative via ground so that made me wonder if I culd use secundary alternator and modify it only to work on me ignition system ? If I wuld put alternator windings in series I shuld be close to that old working principel like old magneto ignition system I do have lot capacitors but only thing I have problems so fare I finding circuet that will not interfeare with me baterry ground wuld placeing diode to negative lead solve this problem? I also figured out why not used ac capacitor banks and pump power directly to capacitors I cinde of wanted to use insulators not to tuch ground on engine. So that made me confused how the old magnetos run on ac but did not shock any one? I heard some where depend on what charge the system runs some chassis will increase in rosting some wont rost at all . So the problem is to finde any old books on interned how those devices worked? So I do lot experimenting with diferent fuel types I did also need dual ignition for that odd porpuse. I try some how to activate twin 4 pin gm ignition modules with 1 pick up coil its realy pain in the ass try to reconstruct circuets. Me engine does not suport waste spark so I do not have lot ways to solve thing Im curirs to know if 1 pick up coil has enough energy to operate 2 ignition modules if not wuld I need to re wire pick up coil with 2 wires is there some methode that can multiply pulse from 2 to 4 pulses? Me car Is old Opel the parts look some what diferent from Amerika market so thats why I have hard time to finde solution to those unusual problems. Basicaly me engin can run at normal compresion stroke and he can work on exaust stroke as well similar to 2 stroke motor so the idea is what Im working on is haveing twin engines . So most similar ignition system what I need is actualy the old jaguar hei twin coil ignition system they also hade that 4 pin gm ignition module as some sort of ignition amplifier so evry thing I can solve so fare . But problem is jaguar distributors gave twin pick up coils I have only 1 coil trigger so Im not so shure how to deal with that problem . Im not shure if that problem can be solved? So yeah unusual problem.
a question sir ..

I plan to make an experimental motor/generator set from two upright Kirby vacuums. I already have a red Kirby Legend 2 & need a second Kirby to use as a generator. To excite the motor field or armature on the second Kirby, the exciter would be a 90 volt DC Bodine permanent magnet motor from a Christie cinema film platter & have it & the second Kirby belt coupled to the Legend 2 & use a variac,a variable transformer in other words to control motor speed & a rheostat to control exciter output to the motor field or armature of the second Kirby.

Weird. I just tossed out a dishwasher and decided to snag the motor out before scrapping it. I swear google is listening to me. I didn't look up anything online, but here is a video telling me what to do with that motor. This isn't something that comes up in most people's recommendations. Mine may work better because here in Murcia our motors run on 120 not 240. Although I think a potentiometer would get pretty hot if you run much power through it. Is there any reason it wouldn't work with a PWM controller? It looks like it should just be a series wound motor when you get done.
Wonderful. Only thing I wish was added was an actual diagram of the circuits in case the wires are not color coded. Just So I could do it I have lots of 6 and 9 wire motors that have only black wires.... and no labels

You and some of the other polite commentators are adding useful information here. I collected some motors, hoping to understand their potential for projects one day.
How do you make smart washer machine run? The one from LG and Samsung. Pancake type. It says 280 V DC. advise please.
So all this time I could be doing my laundry courtesy of a Power Sonic & solar panels... Better not tell the boys at National Grid!
Do you know if there is someone who sells the connector that connects to that 10 blade spade connector?
PERFECT !!!!
THANKS SO MUCH
i search so long for this informationds. Thx alot.
Sir Im wondering wuld car alternator with singel winding coil turn as dc motor if you for exampel put round magnets in the in side and out side on that same rotating shaft?I mean the are round but those magnets are stationary .
Wuld that rotor turn to by dc motor?
I was wondering what wuld hapen if you put pm magnets with rotor coil wuld the magnets stop working canceling ich other out if they are aranged in centrain polarity?
Just wondering what wuld hapen if you use oposing poles ore just atracting poles?
That got my curiuse.
The are several videos on this platform showing a conversion from alternator to dc motor.
Some are not very easy to follow.
We will be looking into this in the future with a view to doing a diy simple cost effective conversion
Ok like the video, but can you connect another motor to output 12V to power a battery charge and then run a 12V bulb from it, this would prevent your battery from running flat and power a light?
nice for a paint mixer but thats it... it runs at a tenth of the rpm so i suppose if it was a 300W motor it will probably now be a 30W ... hmmm very good info there anyways and a great clean and good understandable video :)
It's only a matter of adding more batteries, more Voltage, more Amps as needed
You can run this kind of motor on DC voltage but the battery it can't be more than 7 amps other wise the motor will be burned! !!!😦😦😦😦😧😧😢😳😳😳😳
In combination with an AC to DC regulated 220-240 converter this works fine.
Is it the same wiring for 2p4v or 48v bayterie
Brilliant explanation perfect thanks my friend from uk 🇬🇧👌🏼 liked & subbed
No conversion needed. It's a universal motor!
I need to use this motor wirh little load for short durations as 20mins max . Can a Dc motor speed controller of upto 10 amps be used where potentiometer is used . ? Or that controllee isnt good for here
So it will gonna need a 220v battery to achieve the actual motor horse power right? Or is there a trick to it like using converters?
That's greate work . Ca0n you do same on dryer motor
Great video. But what is the use of converting from AC to DC
It's not permanently hardwired. We used a couple of spade connectors so at any time it can still be used AC.
With DC it can be more versatile and portable
Power it using batteries?
Can we use them for prolong time
Im thinking to use them as a direct drive wheel (simracing)
We can make solar fan with this
@@DrivewayDudesrunning this universal motor on dc current does it give u high torque becoz i using this motor for e bike by connecting 24v batteries in series to get 72v is it enough for motor run at high torque plzz reply
How much torque do you have
that was awesome, so would it spin twice as fast if we connected a second 12 volt battery in series yielding us 24 volts?
The more volts the faster it will spin
@@DrivewayDudes thanks, so if you had enough batteries in series, would it spin as fast on the original AC voltage?
@@Good-Enuff-Garage This motor is capable of 11500rpm so connecting enough 12V batteries in series (20) may do it.
@@DrivewayDudes thanks, I am learning so apologies for asking all the questions, now why can't we get the spin speed from the higher amps of the DC batteries, I mean isn't power power (v x a = w)? ha ha
@@Good-Enuff-Garage as an example: 2 x 12V 7Ah batteries connected in Series would be 24V and 7Ah. In Parallel voltage remains the same at 12V and amps doubles to 14Ah so 20 x 12V 7Ah batteries connected in Series would be 240V 7Ah and the same amount connected in Parallel would be 12V 140Ah
The last washing machine I pulled apart used a 3 phase induction motor, with a variable frequency drive. All previous were single phase induction motors. Where are you that they use brushed motors?
Brushed motors are still about. We were given this by an appliance service tech who had it as a replacement for an old washer but was never used
i pulled apart "millions" of machines while working for a recycling company, around 50 per day and the machines manufacturers used solid rotor induction motors up until 15 to 20 years ago,back in the day the motor start capacitor was a big failure point...... then they switched to brushed motors up until 2010 more or less bringing the top failure point to the wear of the brushes...
the majority of the washers still around are brushed motors atleast in europe. cheap washers still use brushed motors...most modern big capacity ones now are direct drive and dont use brushes. those motors seem very reliable but they fail due to tachometer failures and control modules are also very failure prone
@@MrHBSoftware what do you mean when you say tachometer failure.Are we talking about the controller of the motor and not the motor itself ?
@@das250250 on brushed motors the tachometer is a copper coil at the back of the motor and inside of it its a cylindrical magnet ..that provides motor rpm info to the washer machine control board.. the more rpms the more voltage is generated at that coil...usually it has 2 thin red or yellow wires coming off of it... on direct drive systems sometimes there is a hall effect sensor like in 90's car ignition systems but other approaches may be used..i havent taken apart many direct drive machines, and the one i have worked on are mostly "LG"brand, and i can only speak for european market machines.... if you want to check my channel i do appliances repair and vintage vacuum tube equipment restoration
The other type of motor used, are single phase induction, cap start, reversible. One direction runs the agitator in the washer, and reverse brings up fast spin cycle - function is through the transmission based on direction (GE basic top load ca 1990's)
Important things to know.
Max current?
Ratet current?
Continuos current?
If use 12 volt 20 ampere, how many rpm will get? And then check the motor, it's hot or not?
Thanks for the video
I have a dishwasher motor to try this. Keep posting sir.
Hello sir are you familiar with baterry de sulfation usein 1 dead baterry 1 fully charged and 1 dc motor?
Some peopel did done it suposedly because they did not have baterry charger so any usefull info about it?
Suposedly it culd work with transformer/baterry/dc motor as well so that cinde of got me curiuse .
You can connect a good battery to a dead battery in parallel which may partially charge it if it is not beyond recovery. Running a motor using both may drain the good battery quicker
@@DrivewayDudes well thank you for response I have strange projects so I was wondering culd I cutt windings in half on starter motors field winding ore if it is magnetic starter motor to cutt out 2 brushes from the 4 brush holder Im looking for those old sg's ore compound motor/generator patents but cant finde any thing usefull about it .
Aperanly delco hade 4 commitator brush starter/generators ore those were some rotary inverters/converters/transformers so I was wondering do you know some thing about those old designs how they worked and how to coppy them?
Well to be honest Im surching for alternative methodes to run me ignition coil so I was wondering if I culd some how modify me starter ore alternator to act cinde of those old dynamos if me ignition coil for some reason get fried I wuld like to have back up plan some sort of .
I have constant problems geting voltage to me ignition coil who is E core type hei with 4 pin gm ignition module I have that starter motor r terminal bypass wire but it aperantly works only at points not on hei so any ideas where I can draw curent directly to me ignition coil?
Me alternator is old delco 12 si it has that odd bypass pins for rotor so I was wondering can I draw curent from there and use capacitor in series with me ignition coil wuld that work?
At this stage I dont realy care If I fry some thing I just need some back up plan to solve low voltage.
I did try out plasma ignition first it was nice faster spining starter motor ,bether smuther engine but I come acros problem me starting charge rpm from 1200 goes up to 2500rpm thats when I use hv capacitor to coil + and simply ground out capacitor other side to chassis .
So I have cinde of problem with me reference voltage to me baterry so any ideas how this problem can be solved??? I have multipel of those old gm parts so I was just wondering how I can bypass dashboard some how I have voltage regulator inside that thing its anoying so I was also wondeing if I culd stuff up some nails in me starter selenoid and wind that thing in series ore pararel with me E core type ignition coil but Im afraid to fry some thing .
So please any thing you know that might help me with me unusual problems?
I experianced lot unusual things with me alternator similar to plasma ignition was failing voltage regulator gived me similar effects but it fryed baterry so that also made me wonder can I use capacitor banks and drive just me ignition coil with ac and how wuld I prevent me baterry to get fried?
@@MechanicForGMCCars Schottky diodes allow voltage to travel one direction only. Capacitors can be helpful if you are familiar with them or they can be dangerous to very dangerous if used incorrectly. Gate transistors can also be useful. And of course fuses can save your equipment in the case of voltage surges
@@DrivewayDudes well to tell the truth have no realy money so I cinde of must steel staff like canibiliseing me pore mothers micro wave oven .
So I cinde of have plenty hv capacitors hv diodes some rectifier diodes I do have some old psu from computers lot small electronic devices scavanged over the years .
But still Im not so shure to fumeling with any thing.
I did was some what curiuse to fumel with alternator and I noticed that thing is cinde of going to baterry negative via ground so that made me wonder if I culd use secundary alternator and modify it only to work on me ignition system ?
If I wuld put alternator windings in series I shuld be close to that old working principel like old magneto ignition system I do have lot capacitors but only thing I have problems so fare I finding circuet that will not interfeare with me baterry ground wuld placeing diode to negative lead solve this problem?
I also figured out why not used ac capacitor banks and pump power directly to capacitors I cinde of wanted to use insulators not to tuch ground on engine.
So that made me confused how the old magnetos run on ac but did not shock any one?
I heard some where depend on what charge the system runs some chassis will increase in rosting some wont rost at all .
So the problem is to finde any old books on interned how those devices worked?
So I do lot experimenting with diferent fuel types I did also need dual ignition for that odd porpuse.
I try some how to activate twin 4 pin gm ignition modules with 1 pick up coil its realy pain in the ass try to reconstruct circuets.
Me engine does not suport waste spark so I do not have lot ways to solve thing Im curirs to know if 1 pick up coil has enough energy to operate 2 ignition modules if not wuld I need to re wire pick up coil with 2 wires is there some methode that can multiply pulse from 2 to 4 pulses? Me car Is old Opel the parts look some what diferent from Amerika market so thats why I have hard time to finde solution to those unusual problems.
Basicaly me engin can run at normal compresion stroke and he can work on exaust stroke as well similar to 2 stroke motor so the idea is what Im working on is haveing twin engines .
So most similar ignition system what I need is actualy the old jaguar hei twin coil ignition system they also hade that 4 pin gm ignition module as some sort of ignition amplifier so evry thing I can solve so fare .
But problem is jaguar distributors gave twin pick up coils I have only 1 coil trigger so Im not so shure how to deal with that problem .
Im not shure if that problem can be solved?
So yeah unusual problem.
If you were to increase the voltage from 12 Volt to 24V or 36V would that increase the maximum rpm up to 11000rpm.
Yes, a higher voltage would give you more rpm
Nice video, but how could i wire an ac generator head motor to produce dc 36v or 48vdc ?
Super video brother. (Thanks)
👍
@@DrivewayDudes plzzz reply that will it give high torque
This is DC-EL motor as it is posted on teh label. Can run on AC or DC
a question sir .. I have a new motor for a washing machine .. it is 220 - 230 volt .. so if I bring many batteries that will calculate at the end of 230 volts .. will the motor run with no problems at the full speed and with all it's power ? (watt) ? I mean is the idea of AC and DC motors is how much volts I provide for them ? not matter if from a battery or from my house electricity ?
Very interesting, thanks for the vid, you could share a bitmap link showing wiring ?
Why is it motor only have two cables coming out?
Thank you, now I understand how to do it by myself
nice to know how much power the motor has in AD then DC
Thank you for your input and speady reply I most serenely will keep you in the know with this build when its all said and done should be the talk on all the lakes home made cost nothing but a bit of scrap junk and time so looking forward to tell you the good news when I finish construction of my outboard motor
Again thank you and happy holidays to you and yours

Can I do this with a compressors
I plan to make an experimental motor/generator set from two upright Kirby vacuums. I already have a red Kirby Legend 2 & need a second Kirby to use as a generator. To excite the motor field or armature on the second Kirby, the exciter would be a 90 volt DC Bodine permanent magnet motor from a Christie cinema film platter & have it & the second Kirby belt coupled to the Legend 2 & use a variac,a variable transformer in other words to control motor speed & a rheostat to control exciter output to the motor field or armature of the second Kirby.
That sounds like fun
i hope you are not trying to make some free energy contraption
Can anyone tell me how much torque or hp this has in this set up please?
I enjoy playing around with electric motors as a little hobby and this is the first I’ve heard of this. I didn’t know this was even possible until now.
Great video! Liked and subscribed!
Do you got an answer to this question?
Probably so little that you could have stopped it with his bare hands
You made a comment on Mark Christopher about live life claim you are so right we need to have something more better to go about this live life claim..

Sir what will happen if 48 volt 16amp power given to this motor instead 12volt power?
More rpm
Weird. I just tossed out a dishwasher and decided to snag the motor out before scrapping it. I swear google is listening to me. I didn't look up anything online, but here is a video telling me what to do with that motor. This isn't something that comes up in most people's recommendations. Mine may work better because here in Murcia our motors run on 120 not 240. Although I think a potentiometer would get pretty hot if you run much power through it. Is there any reason it wouldn't work with a PWM controller? It looks like it should just be a series wound motor when you get done.
Wonderful. Only thing I wish was added was an actual diagram of the circuits in case the wires are not color coded. Just So I could do it I have lots of 6 and 9 wire motors that have only black wires.... and no labels
Thx. I'll use this for my computer fan
Would it not work better with a PWM controller? What kind of wattage are you dealing with under load especially
Hi it would be very big help if you could help me with the
following
I watched your video is very good but my motor got 7 pin connectors
and got a separate earth connection, I have eliminated the 2 wires coming from
the speed sensor, but I am confused because there are 6 wires coming from the
inside,
Red & Black together, Yellow & Green together and then
I got 2 thin blue wires could you please help me to connect this please
The 2 thin blue wires comes from the front of the motor and the
other comes from the back of the motor
Whete can i get this type of potentiometer
If this is an AC rated motor how is it functions under normal conditions. Are the field windings supplied with a rectified voltage or AC v?
It is a standard off the shelf single phase brushed AC motor.
can that motor be reversed by connecting same wires differently?.
Could I convert a small apartment size refrigerator from AC to DC? I want to do it for my camper. Will it work?
The quickest and easiest way would be to use a DC to AC inverter so it can be put back into your apartment when not used in the camper
@@DrivewayDudes Thank you. I know I can run it on an inverter. I want to be able to run it on 12 volt so the inverter doesn't have to be on all the time. I want to take the works out of a refrigerator and create a built-in refrigerated space in the back of my teardrop camper. I know I can buy 12 volt refrigerator components to do that, but they cost $800 to over $1000. If I could convert the works of an apartment size refrigerator, it would only be a couple hundred dollars.
@@propagantidote Caution. It would not be recommended that you disassemble a refrigerator unless you are a professional in that field. Refrigerators contain a gas called Freon which is quite toxic. A leak however minor and if inhaled can cause respiratory problems
@@DrivewayDudes Yes, I know about freon. I used to be an autobody technician. I've discharged and recharged many auto air conditioner systems. My question is just about the AC to DC conversion. Can it be done? If not, I'll do something else.
Not looked at refrigerator compressor motors so we'll get back to you on that
What's the value of the variable resistor? What's the wattage?
Dudes can you put up the circuit for better understanding. Thank good job!!
Please watch the video. We tried to show clearly and with explanation the wiring configuration.
The colours may vary for different makes and models and may also differ in other countries
How long does the battery power last? Can I make this way a boat crematorium?
What sort of running time per charge would you expect from a car 12v battery? I too am contemplating making a small electric boat motor from either washing macuine or Vacuum cleaner motor? Thanks for a clear and consise video.
That would depend on the Ah (Amp per hour) rating and load on the battery. The bigger the Ah rating the longer the battery will last between charges. You could also consider running a couple of large batteries or several smaller ones in parallel
WOW
try the motor off of a cordless drill...much smaller, more power
Good vedio sir it is use full for sevaral experments thank you
Where/what appliance can you find those high amp potentiometers?
Electronic parts stores - what he is using is a high power rheostat. He does not give the resistance value, but is probably in the 100 ohm range.
Its mean not necessay to convert into 12dc could we used 24volt battery also with same connection.? ?
Why does this work? Does it work on all AC motors? How many of those batteries do I need if I want it to run as fast and strong as AC?
Read a little bit about "universal motor motor" you will find some of your answers
Could a 24v or 32v 48v. Be used also
Yes. We've tested it using various DC voltages.
So is there a circuit board on the motor for it to run ac also
thank you for posting your interesting & well-presented video
👍
And how many amps using this motor from the battery???
The battery used was 4.5Ah. You could try pull more Amps under load but the battery would run down quite quickly
