- Howdee fellow tinkerers :) ,
I wondered watt wood happen if I altered the windings on my Alter-Motor project from Star to Delta configuration.
Well, the results were well and truly worth the effort, as this arrangement offers greater torque and a wider RPM range for the same supply voltage and armature current.
In addition, it seems to be more power efficient, but I am yet to truly confirm that.
All of the systems I have recently seen on RUclips use the Star configuration, as that's how the alternators are made at the factory.
Since I had modified mine so heavily for the gasifier project, it was a simple matter to rewire it for Delta operation.
The benefits were immediate, and I am sure that I will be sticking with this arrangement as I develop this Ebike project during the course of this summer :) .
Now, if I can get it going along at 20 MPH, I will be all smiles, albeit toothless ones. 
Наука
LOL at the *BUTT HURT* flunts and religiots who are TRYING to dislike my videos.
Is that really the 'best' you dimwits can do?
Sucks to be you!
That's pretty cool to see that alternator wired up as a motor. You normally see people do it the other way around turning old washing machine motors into generators.
For sure. The majority of these spinny things are being harnessed as power generators, so it is nice to buck the trend now and then :) .
This thing goes like a rocket, so I am hoping it will push me and my bike along at a respectable rate of speed.
Now that summer is coming along, I can have me some good times out on the roads with this beastie, assuming it actually works.
Steve, I've never seen anyone have as much fun with electronics as you. So, you are going to mount that 10,000 RPM adulterated motor to a bike with an 18 speed transmission. Drop in for a coffee when you go by. ;)
Howdee Bill,
Yup, electronics and I go back hundreds of years. Well, OK, in my dreams ;) .
Warm up the coffee pot, as I will be aiming my front wheel in your general direction perty soon.
Ya know, this might be fast enough to outrun even the fastest of those pesky little neck nippin' woodgas bugs :) .
I love it! I am a Welder/Fabricator by trade now retired & been given the honor chief cook & bottle washer. I have been trying to wrangle enough info in order to turn my alternator into a motor to power a bicycle. I know "diddley" about electrical and anything with a battery. The alternator I have looks a lot like yours so I am hoping you may have a video that shows how this is done? Maybe? Don't hurt to ask I guess.If nothing else I get to say hello from North East Texas and a fellow tinkerer or stinker I'll have to ask my wife but thank you for the video. 9000+ miles per hour? Wonderful.
Howdee, my fellow maker of things - from other things :) .
I would like to retire, as you have done, but my boss has other ideas, as does my my employer, so I am yet to be promoted to chief cook and bottle washer status.
Once you get started on the alternator-to-motor project, you'll find that it is quite an easy process.
While I don't have any how to videos on this, I am sure that I can give you plenty of pointers on how to do it.
You'll find some videos here on YT about this, so these will also be helpful.
Please feel free to get back to me on this, once the dishes are done ;) .
Well I'm t least glad to see someone mounted their test in a vise instead of letting the motor simply lay on a table and go where ever unrestrained.
Yup. That's a common mistake, when playing with spinny things.
It is all good fun, until someone chips a fingernail ;) .
Can't wait to see what you do with this. It's a good thing you have hobbies for indoor activities when it rains. Otherwise you might start talking to yourself or your animals. You might even start hunting the imaginary wood gas bug. Thanks for sharing. Joe
Howdee Joe,
Ahhh, too late. I always talk to myself, and I win most of the resulting arguments too :) .
My animals answer me most of the time, until they fill their chops with carrots, that is.
Having lots of different hobbies is the spice of life, and it renders us essentially immune to the dictates of the weather.
That stated, I wood really have loved to have been outside all weekend, as I am an outdoors kinda dude at heart :) .
Steve, that is amazing. The 10K RPM is wild. And, you are going to put that on a bike........
Helmet and goggles will be in order as well as leathers..... Hope you have good insurance..
Very cool.
Howdee Mark,
If I gear it down, about a million to one, it ought to go nice and slow, so I can climb straight up the sides of buildings, for easy parking in the city.
Hmmm, I better add a parachute to my safety kit, just in case the wheels start to slip a little bit ;) .
And to slow you down should your speed controller go haywire to full throttle. Hang on man,,,,,
LOL. I am allergic to the effects of falling off at high speeds :) .
Perhaps I will add some sort of safety cutout switch, just in case.
Good stuff Steve !
Howdee Terry,
Nice to read from you again :) .
Here's hoping all is well at your end of the gasifier plumbing?
Ya got ur Skype on?
Yup, just started it now :) .
Very nice
Thanks kindly :) .
Well done! Interesting idea . Did you have any problems with the polarity of each winding?
Thanks kindly. This works like a charm, and I am now looking for other uses for this kind of motor :) .
Oddly, I don't seem to be having any problems with the relative phasing of each winding.
I really thought it would be an issue, but it seems to work, no matter how careless I am with this aspect of it.
It is possible that the controller carries out some tests before it begins working, so as to automatically resolve this issue, but that's just a guess :) .
CNCmachiningisfun. If you assume that the original tappings are U1 V1 W1 and the star point tails are U2 V2 W2 , then connect the phases L1 to U1V2 , L2 to V1U2, L3 to W1U2, the same as IF you were connecting up a standard 3 phase motor in Delta . I imagine that you have done it this way , otherwise you may have a nasty judder in the motor.
Keep up the good work.
+psob1
I did try a number of variations in the basic theme, to see if I could get the motor to fail, but I worked, no matter what I did - as long as I followed either the Delta or Star scheme.
To be sure, I would probably set the bare alternator up with an oscilloscope, energise the rotor coil, turn the rotor, and observe the classic 3 phase signature emerging from the designated outputs.
Upon getting these wrong, I am sure I would literally see the defects in that 3 phase signature :) .
Thanks for your good thoughts and ideas here.
CNCmachiningisfun. Thanks, that's interesting, mind those fingers though.
+psob1
Oops!
Too late on the fingers thing.
I am down to my last five digits per hand now ;) .
Ok thanks for your help 😎
Thanks for sharing this amazing project. How efficient is your Alternator Motor?
Thanks kindly for the positive review :) .
As for efficiency, when I compare the mileage per unit of power that I get from this Alter-Motor with that of standard EBikes, I find that it performs surprisingly well.
On average, it draws 15 watt hours per kilometer, which is better than a lot of the other ebikes that I have seen lately.
Perhaps it could be improved further, but I am not sure just where the limit truly is.
Seen this vt " understanding star-delta starter" now I understand it
could you explain in more detail what you mean about the star configuration and the other one, do you mean you took the alternator apart and redid the windings?
Howdee Sean,
When you take the rectifier stack off the rear of the alternator, it exposes 3 stator coil leadouts.
Each of these goes to one of the ends of the 3 coils that form the stator windings.
It you look a little deeper, you'll find the other 3 ends of those coils.
These are all twisted together, soldered up - and insulated.
I separated these 3 wires, and brought them out of the rear of the alternator case.
What I now have is 6 wires that lead to the 3 individual coils.
The original electrical setup of the alternator is referred to as Star configuration.
To make it into Delta, I simply joined the end of coil 1 to the end of coil 2, and the ends of coil 3 to the remaining ends of coils 1 and 2.
That might sound complicated, but you'll find that it is super easy when you give it a try :) .
@@CNCmachiningisfun I think what you made was a 6 phase motor. Great video, thanks for sharing.
@@jessemeanlt1
Thanks kindly :) .
It would be cool if I could make it a 6 phase motor, as I am sure that I would get it even more torque from it.
Alternators make good, and very tough, little motors :) .
Should be able to outrun the cops on that Steve!
LOL, yup.
Ain't no coppa gonna get me ;) .
Once I reach 88 miles per hour, I can throw flux capacitors at them, and send them back to the future.
CNCmachiningisfun . Actually Freds got one. He's not using it in his Delorean anymore since it caught fire at 20mph. Have you got room on that thing for that?
Hehehehe, yup, those self igniting Delorians can be a bit of an embarrassment at times ;) .
It it will fit in a shoe box, I reckon I will have room for it.
Those naughty coppas better watch out, as I will be able to travel in time, and really ruin their day.
I just pulled a couple from the scrap yard apart. One is a pig to get the rectifier, slip rings and regulator apart and has no rotor current. It is star configuration but there are 6 tails going into the star point junction and 2 for each phase so I'm thinking there are 6 coils. I wonder if you could separate them and run 2 escs?
The other is a 115A delta configuration with slight regulator damage from an accident. The rotor pulls 3.8A and looks to be a very good alternator. I was planning to use pwm to control the rotor but someone told me that will mess with the flux and give poor results so I've ordered a 50w 100 ohm trimpot. I'm really hoping that I will get 10000rpm following your example but doubtful because it was already delta.
I'm glad I found your video as it probably saved me a day of testing which is why I'm interested in your exact numbers. I need to get to 18000 rpm so I guess I'm going to need at least 24v
I'm in NZ by the way
6 wires at the star junction tends to suggest a bi-filar winding configuration for each of the 3 phases, so it is best to keep them paired up when you try out either the star or delta configs.
You will not be able to use two ESCs, as they will fight each other, and release the magic smoke!
ESC smoke smells nasty.
It is best to avoid PWM, as this will produce a pulsing effect in the stator windings, which will interfere with the timing of the sensing function in the ESC, and cause erratic operation.
There are ways around this, but your 100 ohm rheostat solution is the better one for now.
My exact figures will not mean very much, as your alternator will behave differently from mine under the same circumstances.
Experiments are in order, to see if you will get the required torque at the required RPM.
Torque falls away as RPM increases, for a given supply voltage.
18000 RPM is quite high, so yes, 24V seems like a likely working voltage for this :).
NZ is the best country in the world.
No bias, of course ;) .
Getting correct materials in the morning I was wondering is there a way to run two of these motors in series ???? as I'm new to this and I'm more used to the brushed setup that iv got on my quad conversion
That's great. Soon, you'll be ready to run :) .
Unfortunately, you'll not be able to run two or more of these motors in series or parallel.
The only way to run two or more of them is to put an ESC on each motor, and drive the ESCs off a single throttle controller.
Thanks for share. I'm starting a project similar to that, on my you tube channel.
You are welcome :) .
I look forward to seeing what you are building.
You will have a lot of fun with it, once you get it running.
Wow!
How many volts did you use in order to get to 10k rpm?
Think an alternator can hold 72v?
Or is 48v plenty?
Planing on making a go cart :)
I was running this on 14 volts when I did this video.
At that voltage, you can run it really fast, but there is hardly any torque in it.
Your alternator will handle 72V, but only if you are ready for the sheer grunt that you'll get from it :) .
48V is pretty safe, and it's gonna be pretty quick too.
Yer go cart will go like a rocket with an alternator as a motor :) .
Ok thanks and I have built it just needs motors the aircraft controller your using they do rc versions do thay still work even tho they smaller ??
My ESC is for RC aircraft, so it is very small and light.
It will make your cart go, but not too well, as these ESCs are not as powerful as the ones for EBikes.
How many Volts and Amper produce this alternator by factory data in alternator(generator)mode?Thanks
Iv got it apart now do I connect the 1s that beep iv got six sets of wires coming from the stator windings ??
Best to make a video, showing all those wires in the back of the alternator.
Ok thanks I'm ordering a speed controller aswell tomorrow what's the best type I will need it to test this moror ?
Any ESC that can handle 60 amps, and at least 4 Lipo cells will get the job done.
Also, you will need a servo tester, so you can send speed control signals to the ESC.
These will let you test your new motor :) .
ESC means, 4 lipo cells means, where can get servo tester
Thanks it needs 2 monster motors in it 😎😎
How put i in delta
First stage of delta wiring to the alternator
Good start :) .
Attach a fairly heavy wire to each of those copper pairs, so you can bring all 6 of them outside the alternator shell.
Attach smaller wires to the brush connections, so you can close up the alternator.
Thanks iv just realized what the difference in 2s - 6s lipo 😂 it's the power difference how many can they hold at once these esc 1 cell or more than 1 ??
Your ESC is rated for 2-4 Lipo cells, if I remember rightly.
Each Lipo cell is typically 3.6V, which means that your ESC operates on 7.2V to 14.4V.
My EBike runs on 14.4V, which is OK for such a light bike - going at 12MPH.
Your system will work, but its speed will be limited.
Gracias por compartir.. Que voltaje utilizas en las escobillas y en estátor?
You are welcome :) .
I use 5 to 12V on the brushes, and 14V on the stator.
@@CNCmachiningisfun are you still with this alternator?
@@foxxyytofficial
Yup, I am still using this alternator as a motor for my bike :) .
@@CNCmachiningisfun do you have a more recent video to show using it with 36v?
@@foxxyytofficial
Sorry no.
I tried to upgrade to 36V, but my new controllers simply weren't up to it, so I never got beyond the previous setup :( .
Iv bought maximum rated wire at 240 volts 38 amps 6mm or is it too thick or is it good ???
It's thicker than you really need, but it will be just fine, as long as it is not too stiff for you to work with.
sir wall job plz explained me this alternator wache car use and haw many ohms rester use plz answered me thank and I used 1500w controller good job haw many volt batteries use
Check this vt "converting a car alternator into a kart motor" a few mins in the vid he shows how to wire the delta configuration is this the same as yours ????? And when it's wired is it like it's being wired in series that's what picture I'm getting from watching it or am I wrong ????
Yup, that is a good video from Austiwawa.
If you follow that, you'll be most of the way there :) .
Good work. On my chanel alternator pushing the car 600+kg. Connection star. 57v 40a. Controller.

She's gonna be slow, certainly no faster than mine at about 12MPH.
This is good for testing, but not so good for traveling.
Thanks Least we will know if iv done it when wired up have you seen my new vts ??
Great vids. You are doing a good job on these carts :) .
Just remember that your ESC is limited to a battery voltage of about 14V.
Going higher than this will let the magic smoke out!
Some1 has a vt of a alternator conversation and it spins at 30 thousand rpm have you seen it ?
Nope, I don't think I have seen that video.
Bear in mind that a fast spinning alternator is likely to have less torque than a slow spinning one.
Mine will easily do 10,000 RPM. but I usually run it at no more than 2400 RPM for practical use on the bike.
Hello,
Do you know the resistance of the single coil by any chance?
Thanks,
The DC resistance of each field coil is VERY low.
It's about 0.3 of an Ohm.
The rotor coil is around 2.5 Ohms.
Thanks, Much appreciated.

That's gonna be a problem, as the maximum supply voltage will be about 14V.
It will work for low speeds, but it will quickly run out of puff at higher speeds.
For a fast and powerful cart, you will need something that can handle a battery voltage range of 48V to 72V.
This is where an EBike controller is your best choice.
RC ESC is good for testing.
Ebike controller is good for proper, powerful, road running.
I want to wire in delta format but can't find a video to copy it is there any where I could find it ???
It's very easy.
Take out the rectifiers, to expose the 3 wire ends.
When you are hunting around in there, you'll find 3 more wire ends that are soldered together.
These are the opposite ends of the wires you exposed when you pulled out the rectifiers.
Separate those 3 clumped wires, and attach new wires to them.
Do this with the 3 original wire ends, and most of the work will be done - in preparation for the next step in creating a Delta wiring scheme.
I'm working on something and wondered if I could email you something to show you
Can you make a YT video about it?
That would be the best way to go.
as Usual you tube like every other web source has made it harder to message. How did your project turn out? I tried the same setup as CNCMachiningisfun It is driving me crazy .I have the same controller does it have to be programmed or tuned. I used two Chevy 65-72 alternator bolted together with a 3/8 turn buckle. Im just working on the motor now soon to belt drive the other as a generator. Im a retired craftsman who had a stroke so you can imagine it takes me a week to do anything.
And a multi servo tester it looks bit like yours 😎
Yup, that will be good for these.
Just remember to use only ONE of the BEC leads, lest they interfere with each other.
BEC leads means
What kind of battery and voltage did you used for the rotor also for the stator ?
From battery how did you convert it into ac supplyed to the stator what did call that thing and why is it you apply risistor to the rotor before the battery?
I used a 4 cell, model RC LiPo battery for this. It delivers 14 volts to the system.
A resistor, about 5 Ohms, limits the rotor current to about 1.5 to 2 Amps.
The resistor allows the motor to go faster, while also allowing it to run a little cooler, but it reduces the torque.
You can run it without the resistor, but it runs slower and draws more power from the battery.
A 60 Amp RC aircraft ESC converts the DC to the AC used by the motor.
When you run at lowest rpm (6000rpm version) what is the rotor current and what resistance? Same for max rpm. And at 10000? How many amps is the alternator rated at?
The resistance I used for this ranged between 12 and 24 Ohms, which makes for a current that ranges between 1 amp and 0.5 amps.
Lower resistances translate to higher currents, which provide lower RPM and higher torque.
This alternator is rated at 100 amps.
CNCmachiningisfun r
Hello I've built a go kart and it needs a powerful motor like this is there ant Wat possible you could do a video in how to this this configuration in more detail please and you are brilliant 😎
Sorry for the spelling
These kinds of motors can deliver a couple of horse power, so that ought to get you moving quite nicely.
Mine is not very powerful, as I have used cheap parts to make it work, but it's good enough for a bike :) .
You might like to take a look at RUclipsrs: Austiawa and Tchangly21 for more powerful examples of alternator to motor conversion :) .
Ok thankyou for replying what I have actually done is converted a petrol quad to electric I have a 24 volt 500 watt motor the power source I have made is lead acid 6 6volt 12 ah batterys wired in series to create 36 volt I'm also using a 36 volt speed controller 800 watt with all this I seem to only gat a mile before it runs out of juice any advice for me please ????
Those kinds of batteries have a rather poor performance curve at high power levels, so they will tend to drop out pretty quickly when pushed hard.
You'll probably find that one or two of them run down much more quickly than the others, which will drag the whole lot down.
One thing you can try is two stings of 3 in series, wired in parallel for an 18 volt system - with twice the current handling ability.
It won't be as fast, but it will go a lot longer :) .
Thankyou for your time in replying I will try that configuration I also bought a denso alternator today iv just finished a quick bench test iv wired it correctly with an ignition bulb from b+ to feild and no light comes on is the alternator blown or a part inside it I'm a Newby
Do you use hall sensors ?
This is a sensorless system, but it seems that I could get better performance if I closed the control loop with a set of sensors.
can I replace servo tester instead of 10 k potentiometer
Sorry, but no.
You need to deliver a stream of carefully timed pulses to the ESC, which is what the servo tester does for you.
Do i need to rewind it or not?
No, you do not need to rewind the alternator.
So if the stator only has 3 wires coming out of it then it's a star configuration right?
That would be Delta configuration - where the 3 coils are all daisy chained together, with 3 wires connected to their junctions.
Star configuration has a wire, that goes to the end point of the 3 coils, and 3 more wires that come from the other end of the 3 coils.
I brought 6 wires out of my alternator, so I could experiment with the various wiring options.
The thing with my alternator is that is only has 3 wires and their every thick wires
@@lt.schlechtnacht9414
You might find that there are 6 wires in there, arranged as 3 sets of 2, that are very close together.
I wish I could show you what I mean the whole stator is like 3mm copper wire. It's very thick. And theb3 wires that come out are very thick as well. It's a 1986 delco alternator
@@lt.schlechtnacht9414
This is unusual.
Maybe those 3 wires are connected to the 6 wires, deeper inside the alternator?
Even as it is, you'll be able to use this as a motor, as it works in Delta *and* Star configurations.

Sounds great :) .
I look forward to seeing what you are building.
2500 watts per motor is certainly possible, if you go with a high enough voltage and current.
You may want to opt for EBike controllers instead of aircraft ESCs like I am using, as those will be more powerful.
Take a look as Tchangly21's videos for some inspiration on this, as he is really heavily involved in the making of speedy electric zoomers :) . .

Ok thankyou so I bring all 6 out all together I'm gunna have 8 wires out the back ???
Yes, that is correct.

Thanks do Any of the wires need to be marked or coloured at all any of the 6 I meen ??
Any old colour will do. I used purple for mine, as that was kinda handy at the time.
To group them, simply pass them through the various holes in the back of the alternator in pairs.

Sometimes, you have to make compromises, in order to get the project done.
As long as there is good airflow around those wires, they won't overheat.

I'm researching star vs delta and came across this. www.electricaltechnology.org/2012/02/star-delta-3-phase-motor-starting.html.As a bike is always starting / doesn't reach operating speed then maybe star is preferable.
A motor with windings in delta configuration gives low torque at low speed, but can give higher top speed.[citation needed] Wye configuration gives high torque at low speed, but not as high top speed.[citation needed]
Although efficiency is greatly affected by the motor's construction, the Wye winding is normally more efficient.[citation needed] In delta-connected windings, half voltage is applied across the windings adjacent to the driven lead (compared to the winding directly between the driven leads), increasing resistive losses.
So my observation about delta lacking torque during initial acceleration is supported.
I asked tchangly21 and he's using star in this video: m.ruclips.net/video/KNJkm6nVcfY/видео.html&feature=em-comments&lc=z22och0i1lfis32nzacdp433oqg32komznk4jycmnu5w03c010c.1511117675283782

There are differences in the performance of these arrangements that justify a good degree of experimentation, which is why I bought all 6 of the wires out of the alternator casing.
I have seen one video where the bike builder added a Star/Delta switch to the handle bars.
This allowed him to switch modes while in motion, and he reported that he was able to boost his top end speed that way :) .
One of these days, I will try this out, as it seems to be a good idea.
Can you remember which video? It emulates the star/delta motor starter, so makes sense, presumably once the motor is near to maximum speed in star mode.
I'm going to use star configuration and change the 12v SLA to a 3-phase rectifier and PWM, to energise the armature when I'm on throttle and to be able to vary the armature voltage. When I rash elta and had no torque, I increased the armature voltage to 48v (which got smelly real quick) but I'll notch it up from 12v and see if I get more torque and if so, where is the voltage of decreasing returns.
Do a video and show a step by step how to video of every you do and use and where to buy the stuff and make sure to show all the labels. There's a lot of us out here that want to do this stuff but don't know squat. I want to link up about 6 altinators to 1 motor to power my home and deep well water pump to totally self powered and off grid with no gas or city power use at all. The altinators need high amps to get the full ac voltage so need the dc motor to run at about 6,000-8,000 rpms with controller and amp & voltage meters on about a 3-4 12 volt car battery bank. Have the first altinator to keep the batteries charged and the others for the house. So 5, 250 high amp altinators altinators converted to ac output for the house current and one 250 high amp dc altinator for the batteries. How about doing a lot of us a favor and doing a video . Please.
There are videos likes that out there, and they are pretty easy to find.
What I did here was an experiment, as I had no idea if it would even work.
Needless to say, I was mighty pleased with the results :) .
It's no good I can't close it up going to have to get thinner wire and take all these off just my luck
Perhaps you can drill some holes in the back cover for those wires?
Some alternators have lots of holes already.
Maybe yours doesn't?
Check my youtube vt" home made alternator tester " all the wires get hot when running the motor to spin it
Nice!
That alternator seems to be working very well :) .
Youre just spinning the alternator with a different motor. Not at all what's going on in CNC's video.
From endless-sphere.com/forums/viewtopic.php?f=30&t=61343&p=917145:
"3.Re-terminate in wye (unless already is), don`t bother with delta, trust me."
I do tend to agree as I've said a few times.

Thanks for that link. It was very entertaining :) .
As for the Delta configuration, it seems to work better for me than the Wye method does.
That stated, I have not tried the Wye config on my bike, only on the test bench, so perhaps I should just check up on that.
CNCmachiningisfun When I first looked at how to wire my phase coils, I thought that Wye was wrong as the alternator ran rough on the bench with no load. I ended up putting it on the bike and was really underwhelmed considering the power input was around 2000w.
When that can switch arrives (usually 2-3 weeks), I'll wire it in and see whether the controller will a accept the two configurations without reprogramming. If it does then I'll changeover on the fly. My gut feel is that the loss of torque will require the bike to be geared much lower, to make maximum cruising speed correspond to maximum power in delta configuration. This will make the bike a wheelie machine in wye configuration.
You've got the test bed for this, as you have the intermediate reduction gearbox. I don't, as I have direct drive. Get a 16s to 20s pack and a 60 to 72v ebike controller and unleash the potential of your machine.

Experimentation is definitely in order for our bikes, as we are yet to get the best from them.
My next voltage step will be to a 36V Lithium Ion pack that I bought last week, but I need to fit my new ESC before I go up in voltage.
The New ESC is rated at 120A and 48V, so this ought to get my wheels spinning a wee bit faster :) .
I dunno if I have the courage to crank it all the way up to 60 or more volts, as I am allergic to high speed road rash scars on my skinny people wrapper!
Check this "world's fastest modded mobilty scooter go kart with glass floor "
That's pretty sweet.
There ought to be lotsa room for batteries and electronics on there :) .
How many Volts and Amper produce this alternator by factory data in alternator(generator)mode?Thanks
This was a 100 Amp, 14 Volt alternator.
Bigger ones may be better motors, but I don't really know for sure.
