Re: [TCML] How To Turn A Vacuum Cleaner Motor Into A Synchronous Motor



Hi John,
not for cooling, more for lubrication purposes. The permanent-magnet rotor runs in a plastic cylinder which isolates it from the coils and ironcore, and this cylinder is flooded with the water when spinning. Sure it runs even dry but I think it will not last very long. Okay maybe it would be possible to fill the cylinder with some grease.

Why do these motors need water?  Is it for cooling?  Maybe a powerful fan
or air blast would be able to cool it sufficiently? I wonder why the manufacturer
would need to use a synchronous motor for a washing machine?

That was a fun video of the over-volted burning motor.... LOL.

Cheers,
John

Here is a link of the motors I will use for modification (please excuse

this stupid video where I kill such a motor with overvoltage):

Here in Germany nearly all washing machines use this type of motor, maybe

in USA there are brushless induction motors arround?
