motor temperatures

[simonb]

could someone tell me as its been bugging me for a while now regarding motor temperatures, along side my repair business iv been refurbishing washers and always ensure each one is safe and sound, i always test with heavy load and if motor is red hot ill change it, what about quiet warm? the amount of times im doing away with motors that perform well under test but feel hotish always staying on side of caution, anyone know the correct working temperature of brush motors?

Re: motor temperatures

Most, if not all, of them have a self resetting toc buried in the coils. I’ve often noticed motors getting a bit hot (enough to make you take your hand away quick) but never worried overly as long as they’ve got a toc. Also the house rccb, where present, should act before it got critical.
Several times I’ve replaced toc’s which have gone open circuit presumably following sevral trip/self-reset cycles. You can get them as spares for some motors. Never had a subsequent call to say machine has caught fire! Hope I’m not inviting disaster.

Re: motor temperatures

I don’t think there’s much to worry about with motors running hot, the TOC will deal with any problems.
The acid test is to mesure the current being drawn, under a known load, if it’s high the motor will get hot, it depends on load. Make up a socket with a test meter in circuit to monitor the machine in the workshop if you really want to test it.

Or you could use one of the now easily available and cheap plug in energy monitors as mentioned on another thread.

Just to put a spanner in the works.

Current Reg`s stipulate that certain safety checks should be made to all appliances before and after any electrical work is carried out.

These include the installation and the appliance.

The appliance tests will test the insulation of the componants within the appliance as ensure they are within safe standards.

Motor temp TOC are accurate to lots of zero`s, so no concerns there.

Although a few “mates” around do tend to bypass the TOC to get the perfectly good motor to work. 😥

It`s amazing though how many motors fail and require repplacing when all you went for was a door seal replacement. 😆

Sometimes they just need taking off and giving a good clean to get the excess carbon dust out.

Re: motor temperatures

hi i was at a zanussi fj1454w machine which i had changed the carbons a couple of weeks ago and the otor seems to be very hot with a hot “burning smell coming off it but it is still working ok.
is this ok?

Re: motor temperatures

You have to be careful. Especially after what Lee8 said about some of his “mates”. 😉

Creo que es mejor trabajar dentro de mí mismo.

En Espana es mejor, la trabajadores son una pequeña molestia.

Ustedes han trabajado en Portugal ?

Re: motor temperatures

Trabalhei como um professor inglês em Portugal há muitos anos.
Você fez máquinas laváveis na Espanha?
O que é inconveniente sobre os funcionários espanhóis?

Not really.

I worked Spain for a few years and returned in 07.

Spent most of the time in Puerto Banus and Marbella servicing the Guiri`s.

Beyond Usted Cuel es la problema con la lavadora, senora, I need help.

Good experience in a strange culture. 😆
