Washing Machine Motor Wiring and Control
Вставка
- Опубліковано 9 вер 2024
- I have a couple of the universal type of washing machine motor. Here I wire one up, showing you how it is done, and also wire it up via a control circuit.
Note, mains is dangerous so handle with caution. I was wearing glove when the mains was on.
The control circuit needs a case because it is live, but you can buy it here:
www.amazon.co....
Though at time of publication they are currently unavailable. They are also available on eBay.
I disassemble the washing machine 2 years ago...i bought the motor controller 1 year ago.. this year I'm going to make a bench grinder 😄
Good luck! On my bench grinders one side has a left handed thread so that the grinding wheel on that side does not end to undo.

Thanks Ben, I've got at least one of those lying about and this wee speed controller could be just the solution. Cheers mate.
Quite useful speed controller. Needs careful mounting as it is all at mains voltage.
Many thanks for watching.
Thanks Ben, good stuff, very informative.
I have a motor the same as this one but the wiring in the 7 pin connector was slightly different: the two tacho wires wer connected to pins 4 and 5 rather than 6 and 7. It took a bit of trial and error (and a few replacement 13A fuses) but I got it spinning in the end. I'm thinking I may build a wood lathe with this.
They are quite powerful so could do that if geared down. You could do with speed control.

Thanks for this Ben I didn't know it would be that easy to control these 👍😊
I had a design and I found these whilst looking for some of the components. It is easy though.
Many thanks for watching.
Handy bit of kit for a tenner for 5 of them. 👍
They are. First practical use will probably be with the sewing machine motor though I will have to work it into a foot pedal.
Thanks for watching!
Very useful vid, cheers mate
No worries. Hopefully you clicked the like... 😉
Really interesting video Ben... Thank you...
No worries.
Quick question... Where did you buy your Dore Westbury mill from, roughly?
@@BensWorkshop It was an eBay purchase and was part of the estate of a gentleman in Plymouth.
Interesting. I was around someone's house collecting a donation to my model engineering club (hand tools, boring heads etc) and he had one he sod a few months back, thought I'd check if that was you, but yours was the other direction.
Wonderful
Many thanks, and thank you for watching!

Hi Ben, sorry I was without broadband for a couple of weeks and only just beginning to catch up on my viewing!!! That was all nice and simple - now I just need to find a project that needs a washing machine motor! Washing machines are a great source of cheap used motors, and that motor controller was a bit of a bargain too.
Hope all is now well with the broadband. Yes, the motor controller is cheap though currently unavailable on Amazon. I can but those motors for a pound a kilo at my local scrapyard though the one on test was free, as someone replacing theirs asked if I wanted it so I removed it myself.
Many thanks for watching!
PS, you may have missed the videos on the London to Brghton veteran car run, and me making a tool to overcome excessiveky tightnuts...
@@BensWorkshop Yep, those are on my "to watch" list - I'll get to see them eventually.....
Thanks Ben, That Video is very easy to understand.
Can you tell me how to identify the wire connections on my motor using a multimeter please?
I have similar 7 wires goinf to a universal 7 pin connector and It is easy to trace 3 of these ,
2 yellow (Pins 7 & 4)= Tacho
1 Green (Pin 5) = Brush.
The other white Brush wire goes inside the motor housing and another white wire reappears and goes to Pin 6
There are 3 wires from the windings Turquoise, Orange and Brown which go to Pins 3 2 & 1 Respectively.
I do not know why the white wire goes inside the motor - I can only guess it passes through a winding.
Is it possible to use a multimeter to verify where the 4 wires go inside the motor without taking it apart and therefore which would be best to use for the best (Strongest) output. I am more interested in strength not speed.
I have a speed controller which uses the tacho connections to control the speed, but I have already blown up one by using the wrong winding/brush wires so would like to be more thorough when wiring the next one.
Thanks
There should be a wiring diagram in the video, finding and viewing it may help.
If you have identified the tacho wires (2 wires) ignore them for now.
You then have a pair of connections to the brushes which should have a resistence to them of between 6 and 10 ohms. You should have infinite resistence to all other pins.
You then should have 3 wires left, these are the stator/field coils, with two of the 3 wires being either end of the pair and one in the middle. In theory if you connect across both you should have twice the resistence of one but in practice there is contact resistence of 1 to 3 ohms. Each coil should be between 3 and 5 ohms. So if one pair of the 3 tests at that range, and the next double that less an ohm or two you should be able to tell. You will want to wire the stator coils so that you are across both at the same time with two wires.
Also none of the stator coils should have less than infinite resistence to any of the other 4 wires.
Hope that helps, many thanks for watching, please like, share and if you like the channel, subscribe!
Hmmm gives me an idea for a project I'm working on
They can be useful.... Just watch out for the mains voltage.
Many thanks for watching.
you dont tell us what cables your ohm testing and what difference is,3 field coils but why 3 ?
If you look at the diagram I drew, there are 2 field coils, with 3 connections, as they are wired in series. So you have one connection at one end of the pair, one in the middle and one at the other end. Hope that helps. If not, by all means ask further questions.

@@BensWorkshop Thank you, All good
You are welcome!
Like #15 Ben
Many thanks, I will be seeing you later.
Please how about a 5 wire motor
I don't have one to test and check and have not personally seen one. What does yours look like?

The wiring is not clear. A picture diagram would of helped much better
Many thanks for watching. There is a picture/diagram of the wiring of that motor in that video.

Five for a tenner, wonder how many of the extra ones go in a drawer never to be seen again 🤔😎
Well, I have two washing machine motors and a sewing machine motor, so 2. :)
Many thanks for watching.
hi ben
Great.
ive always wondered if washing machine motors are useful for anything,
might be simple to you but for us non electrical minded not so.
I wasn't sure from the video were you were attaching the mains to on the motor. Also what sort of h/power are they, can they power small lathes and eg my new little shaper,.
cheers
Kev
When you say you were not sure where to attach the mains to, do you mean on the controller or the actual motor?
Also, you this one seems to be around 1KW, though being universal rather than induction motor they are less efficient. You could power something like a shaper, though I would be more inclined to use an induction motor. I was thinking this sort of motor would be useful for some types of sander.
@@BensWorkshop cheers ben
both motor and controller.
kev
I was hoping the motor part was clear.... Obviously not. The controllers might vary, but perhaps I should do a longer video.
@@BensWorkshop Cheers Ben , sorry don't want to put you to any trouble, but for someone who has not much electrical knowledge , i like to belt and brace things before i commit to pumping electric through it.
take care
Kev
No worries.
Ok, so I have a 5 wire set up. Tacho = 2 brown wires. Then I have a heavier white, red, black. So this appears to be brushless. Does this mean I can't low volt it? E.g. 12v .. the motor states ACC type 20585.123 195v 310hz ac-el 17500 rpm .. can you help?
Does it look like this one?
appliancespareparts.mysimplestore.com/products/hotpoint-indesit-washing-machine-motor-type-20585123-028267f814-16002275900-20585123-028267f814-16002275900-20585123-028267f814-16002275900-fully-tested20585123-028267f814-16002275900
If so, I suspect that the brushes are hidden inside the motor housing. To drive a brushless motor at that speed and power would require an extra cost.
Also from the pictures I have seen, it looks like a standard washing machine connector.
However the stator coils might be wired together with no centre tap and the rotor brushes might already be in series.
Have you tried checking with a multimeter?
@@BensWorkshop that's the very motor. It was pulled from a working but buggered machine, it wasn't a motor failure, it was moisture on PCB from what I recall. So the motor works. Or at least worked. I'm just wondering what I would try Vs a direct 240v here in UK. I was hoping to make a lathe or something from it.
I forgot to add, please like, share and if you like the channel, subscribe! (You will see lathes here as well)
Have you looked at this video where I replace brushes:
ua-cam.com/video/2pNQQqsed78/v-deo.html
Can you see anything like that in the motor. From the pictures it seems they might be burried.
Also check this video out on reversing and speed control:
ua-cam.com/video/8uYmBJt8_Us/v-deo.html
Your motor looks mostly like a standard brushed motor. The brushless ones on washing machines are pancake motors.
How are you getting on with the wiring on your motor?
What power was you using 110 or 220 volts
In the United Kingdom we use 240V for single phase mains. However motors made for the North American market may well be made for 110V.
