Easy Conversion of AC Washer Motor to 12VDC
HTML-код
- Опубликовано: 27 июл 2024
- No tools needed.
Driveway Dudes Paul shows you how you can convert a 230VAC washer motor to operate by using just a 12VDC battery without having to modify, breakdown, dismantle or rewire it.
The rpm can be controlled by the use of a potentiometer/rheostat.
Simply by using just 3 wires as jumpers it is easily done and if you wish, by removing those 3 wires it can again be used as a 230VAC motor.
There are many old motors still about that may have stopped working and all they may require is just a good clean and new set of carbon brushes.
The applications can be whatever you want. You could increase the voltage from DC 12V to 24V, 48V, 60V, 72V, etc and in series or parallel.
You could go off grid and/or use the motor AC with a suitable power inverter

I was so surprised when I tried it out myself that it actually worked
i have several of these motors, in my stash. suddenly they now have some potential. Thanks for sharing
Thanks for posting as most people would not thank this could be done.
well done video

Universal motor
Wow extremely works. I used an old lap top charger for power source. I am building a BBQ Rotisserie and i had an old copying machine motor and a washing machine motor to chose from. I was afraid the coping machine motor would not have enough power to turn Miss Piggy but i wasnt sure how to get the washing machine motor to run with out the coil power source as when i wired the brushes + and - to the laptop charger it had no power. I did just as you said in this video and the washing machine motor was turning. So great video and now i will weld the washing machine belt bucket wheel pully to the metal rod that will go through the body of miss pigy. We will feast in your honor Sir
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.
So do you suggest that it's connected directly to the battery using an inverter??
@@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.
I used to boost vacuums by fitting a bridge rectifier to give DC to the brushed motor as they are basically a DC motor to start with!
PERFECT !!!!
THANKS SO MUCH
i search so long for this informationds. Thx alot.
Thank you, now I understand how to do it by myself
I have learnt something I didn't know and I'm ready to start my project.
Thanks for the video
I have a dishwasher motor to try this. Keep posting sir.
Thank you for sharing your knowledge, very well presented and explained.
Great. Thank you. I been looking for this for long time.
Good, clear and easy to understand video. Thanks, it's very interesting.
👍
Muito bom, parabéns!
Good vedio sir it is use full for sevaral experments thank you
This has been incredibly helpful. Thank You!
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
🚤 👍
In combination with an AC to DC regulated 220-240 converter this works fine.
Nice work!
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)
@@Good-Enuff-Garage ok, thank's.
@@Good-Enuff-Garage what if connect 3 battery in series it will increase voltage to 36v, mean current can be reduced, comparrd to run same rpm from 12v battery?
Super video brother. (Thanks)
👍
@@DrivewayDudes plzzz reply that will it give high torque
Very clear explanation. Thank you
Thanks for the comment. 👍
Thanks for sharing. Very cool
Great video, was wondering about the torque but some of the other comments have cleared that up,
Thanks for putting this up!
All the best,
Cliff
👍
i'm also interested to know about a way that i can reduce rpm without loosing torque. any idea?
👀
@@Man-in-da-shed lol people always get me when they put the eyes I don't know why either but its so funny to me
@@thebrokeway9838 can’t vouch for anyone else but i use to to show I’ve spotted someone I know in the comments generally in a new channel I’ve visited
As in. “ I see you”
Thanks for the nice video Paul. I enjoyed watching it.
Brilliant explanation perfect thanks my friend from uk 🇬🇧👌🏼 liked & subbed
I'm saving this for when I'm on a longer study break, but I'm sure I'll be thanking you so I'll do it now.
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.
Thanks for the comment Rick.
Watch this space as we will have a video up soon which will use an inverter
Very well explained. Also noticed how you don't erm or omm or tut like a lot of people making videos with speech. Could listen to you all day. Thank you for excellent video.
👍
I'm sure those who don't speak as well really appreciate your opinion. Why does someone else have to be bad in order to complement someone who is good, you (censored).
Thx. I'll use this for my computer fan
Thanks a lot for that, time to start tinkering.
Great! Thank You!
OBRIGADO PELA EXPLICAÇÃO
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
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...
Sounds like fun. 👍
Would appreciate a video or a blog...
Thank you very much kind Sir !
👍
Excellent video
It is a good video sir. Keep it up
I took one of these out a few days ago, hooked it up to the mains 😂 works on a drill battery fine, no where near as good tho
@Driveway Dudes Nice work indeed . But does it have enough tork so I'm thinking to make lawn mower from it ? Thanks .
I have a 12v D.C. motor from power bench van seat. I want to add another set of wires to it so I can power it with battery @ 1 end and power something else from the other set of wires ?
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.
thank you for posting your interesting & well-presented video
👍
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?
watch the motor details it's a DC Motor?
also if you wire the brushes and the stater in parallel it will go half as fast but with twice the torque (depending on the resistance of the coils of coarse)
Thanks to youtube i keep power tools and jumper cables in the truck.. never know when theyll cone in handy
The second Kirby motor would need field or armature excitation to function as a generator,otherwise without an exciter,or any excitation voltage,it would not output any current.
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!
So simple wow
Wuauuu very interesting
Ebike components , and the logic of ebike components functions(wired an alternator then realized (a 3 phase pwm was required,,,, think potentiometer can be ‘found’ am glad of this data
Would it not work better with a PWM controller? What kind of wattage are you dealing with under load especially
Awesome!
Good job
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
Excelente 🇩🇴🇩🇴🇩🇴🇩🇴🌎
A question I have is, how long can the motor run on that battery at full charge, full speed???
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
thanks
Thanks for this. Any idea on an estimate of torque . Thanks
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! !!!😦😦😦😦😧😧😢😳😳😳😳
nice to know how much power the motor has in AD then DC
Very interesting, thanks for the vid, you could share a bitmap link showing wiring ?
Nice
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.
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 ?
That is NOT an AC motor it is a UNIVERSAL motor, AC motors are not able to run on a battery, universal motors however are designed to run on both AC and DC.
yes battery wont run an induction ac motor which is widely used in my part of the world on washing machines...i do have a vaccuum cleaner ac motor which is a universal motor but 12volts doesnt provide the thrust it needs
@@fidelcatsro6948 it is possible to use the mains power in combination with a bridge rectifier to get the correct DC voltage you need
a rectifier only make the mains alternating ac to dc at the same voltage of the outlet
@@fidelcatsro6948 that's correct I assumed that the motor worked on mains voltage however you can always try using a pwm dimer
@@jakevangeersom3289 universal motor can also run on AC amigo...because the motor has no magnets, it relies on ac pulses for stator magnetization and rotor for reactive thrust...motors are a variety of plenty animal breeds must see and check properly
I have a question can i connect the washing machine motor to my dc power supply using the alligator clips.the dc supply output voltage is 0 to 30v and 5 amps.
Yes. A motor would not know the difference between a power supply or a battery.
Thank you!
I got it working thank you so much!!!
Thank you ❤
can i run a 90 watt ac motor of refrigerator with this method with 50 amps battery or is better i use a inverter ?
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.
How will it run under a load?
How much work is it capable of doing?
yes with this way you can run every universal motors in your home, like drill, grinder, vacuum cleaner and...
with low turning.
just put 12 v on the power plug.
mccann smoke for what?
no smoke come out.
test it.
a dc ac motor, run at 1/20 of power
good job
👍
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 video, you please do a video of a brushless ac motor using DC power? Thanks
they need motor controller.
esc brushless controller.
without that they can't run.
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
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)
I have a project using a washing machine motor and finding this information is priceless ther are others out there who have channels on this subject but run you about you go right to the point
Nicely done now about the project I am constructing out of such motor for my dingy I intend to make an out board motor the motor is 3\4 hp not sure if that can still be intended for 12\24 volts
As it was a 110 or 120 machine I like what have said a will like to hear more if you do have any suggestion on my project pleas by all means give input I am open to new ideas
That would depend on the size of the battery/batteries you are using. The bigger the better.
You could also consider using a 12/24V DC to 110/120V AC inverter to run the motor from the battery/batteries
To adjust the speed and reverse you could an electric drill or similar with a variable speed trigger that would have a reverse action feature.
Be safe and have fun. Let us know how you get on with the project.
@@DrivewayDudes @David Steinfeld AC in a boat?

@@DrivewayDudes better still .......have all passengers on the boat Fused....Earthed......Watered....Drenched.....Dried.....Whatever ??!! Lol.
How long does the battery power last? Can I make this way a boat crematorium?
Hi Paul. What value was the potentiometer?
Could you run it off a 48v dc supply without screwing up the electronics?
Good job sir
In battery how many hours will be run full charge
IT WORKS!
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?
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
What is the maximum volt dc it can handle? And if they work for a long time, they get hot
Nice video, but how could i wire an ac generator head motor to produce dc 36v or 48vdc ?
So is there a circuit board on the motor for it to run ac also
Ive been researching using one of these for a rail cart experiment. You think it has enough torque to push a cart on track?😊
Hello! It will change torque? Thanks!
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
Hi.Nice video.can it be used as a driveway gate motor
Is it a must that the neutral must come out of the armature winding
this is a universal motor with the coil in series with the armature? - hence the brushes
the level of torque will be very small running it like this, surely?
also a simple diagram would have helped the explanation of what you were doing - a picture paints a thousand words an all that
Thanks for the video btw
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.
Thank you kind sir, That's very helpful.
Is it possible to acquire 30 nm of torque from this motor.
not a chance,maybe 1 nm
can you explain about white wires please that are coming out from motor //and how to use this motor on Ac volts on low speed but high torque ..thank you very much...
Use speed regulator module with ic tda1085c by motorolla or ONSEMI search on google,there is some circuit diagrams or products related to it,torques are the same every different rpm
Wow! A sealed lead acid gel battery from the time shrouded mists of the 80's!!!
