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

["Teslalabor" <teslalabor@xxxxxxxxxxx>]

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
