The minimum RPM speed for Sensoless BLDCM.

Mike P

Hello.

I'm wondering which minimum RPM is available when using Insta-Spin and the Piccolo controllers.

It's about the sensorless 250 and 1000W engines.
Absolutely accurate value is not needed. Is it possible to achieve 20-30 RPM? Under what conditions is this possible?

Thanks.
Mike.

This depends on motor specification, hardware and working condition, like rated speed, rated voltage of motor, phase voltage sensing circuit. For most motor, it's difficult to run smoothly below 1Hz (electric frequency) using sensorless FOC.

Thanks Yanming .
What evaluation boars and software you recommend for experiment with sensorless and which for censored motors?

Have any specification of the motor? Rated voltage, frequency, power, current?
