Functional Test of Brush Motor

Re: Functional Test of Brush Motor

I guess your machine has a Timer/Module board fitted then rather than a seperate motor control module?

There is only one cirucit board that I can see so I would have to say, yes.

If that is the case then that Timer/module may well have an ‘out of balance’ detection system causing this fault or further bad contacts to it need checking out maybe?

I could understand something like this affecting the motor not spinning at all, but I don’t see how this would be a symptom of hearing the motor spinning but no movement.

Hearing the motor spinning……..???? :con:

…but not seeing then eh?

Have you not put the belt back on?

Yes. As I wrote earlier this only happens some of the time not always. It seems to spin fine when there is a smaller size load in the machine.

I know that the machine has a wash load capacity of 5 kilo. If the weight of the clothes and water in the machine is more than 5 kg could that cause the drum not to spin? (I realize that may sound like a silly question but I personally have US made appliances and am not that familiar with using European style machines)

Lack of motor action under load is a classic sign of armature failure.

Is it possible to replace the armature? It looks like the motor can be opened (the screw has an unusual head, like the inverse of a regular screw head).

Thanks

No!…new motor only (or good used one I guess?)

(I know you checked the motor with an Ohmmeter but did you not check it also with a 500volt ‘Insulation tester’ as well?)

500volt ‘Insulation tester’ as well?

Don’t own and they aren’t very cheap.

Simmy, you need to find out what the law is in your country regarding safety. Here in the UK we wouldn’t dream of starting up a business in this trade without a “megger”/insulation test meter. 😯 You presumably don’t have much money so why not look for a second hand one? E-bay might have something, although you’d need to get it insured for its transit to you – they’re fragile.
The Haynes manual will probably (my copy is 18 years old so I’m not sure about the new edition) explain why it is important and as it is written for DIY (do it yourself) it will probably give you a DIY way round it which you could use for now.

I took a government sponsored course to learn the trade (and to get a practical electricians license) and we learned about the megger but there was no mention of a requirement to have one. The instructor taught us about them and we used one but it wasn’t made out to be a must have. I’ll look on Ebay to see if I can find one.

Thanks!
