High speed pm motor
High speed pm motor
(OP)
Dear All
I plan to design and construct an experimental setup with ball bearings which are capable of running to very high speeds as 150 000 -200 000 rpm with a rotor radius of 3-7.5 mm. I need the details of the electric motors that can be used for these range.
I would be thankful to you if you can provide a link for such kind of electric motors and/or producers.
I observed from some papers that PM synchronous electric motors can be used. (brushless).
Thank you very much in advance.Regards.

You might also consider small air turbines such as the "high speed drill" at the dentist, that runs in this rpm range.

Benta do you now such kind of commercial air turbines?
I would be grateful if you can provide a link about such air turbines or high speed drill.

Click "Product Information" then "Air Bearing"
200,000 RPM Air Bearing Spindle with an induction motor drive. I use a 160,000 RPM version of this spindle.
