Cool Components: Ultra High Speed Motors And Drives
Most motors I’ve seen spin at the leisurely rate of 6000 RPM or less (heck, many are limited to 3000 RPM).
My Emoteq BH02300’s can do 20,000 RPM.
I’ve drooled over the specs for motors from Emoteq, Pittman, and Maxon that can do 60,000->100,000 RPM.Â (Yes, I’d love to own one).
But a Swiss company, Celeroton, takes the cake: they have motors and controllers that can do 500,000 RPM!Â Those must be totally groovy.
Celeroton sells brushless motors, drives, and compressors that useÂ their motors and electronics.Â The drives have a minimum speed of 5000 RPM; some models can handle up to 1,000,000 RPM maximum speed.Â The drives (or inverters, as Celeroton calls them) are available in 400W to 3Kw models, and are sensorless (no hall effect, encoder, or other sensors required).
A friend is looking into using the Celeroton drives with a merely fast motor (~100,000 RPM).Â If I get any real world feedback from him, I’ll update this post.
