In case you have not heard how a motor spinning 1500 times a second sounds like, here it is! A fearless support engineer recorded a follow-up demo using a Servosila SC-120R servo drive. This time no payload is attached to the motor to preserve the sound.

In this demo, a little 6-pole motor spins 1500 times a second, which is 90,000RPM, which is 4,500 electrical Hz, which is 270,000eRPM. This is achieved under Sensorless Field Oriented Control (FOC).

The rotor accumulates so much kinetic energy, that it then charges the servo drive's mighty DC-link capacitors from 10V to nearly 70V, while decelerating to a stop.

The clean 1500Hz tone produced by the spinning motor reminds of the video games from 90's.

Wishing you an exciting and prosperous 2026!

Happy New Year!
