Hi there. Wondering if anybody successfully used Arduino PWM control to run these kind of motors with built-in drives: 36D Long life brushless DC geared motor, 24V 90RPM - RobotShop. The spec for the motor advises PWM frequency of 15 to 25kHz but Arduino Due (in my case) frequency is 1kHz (analogWrite() - Arduino Reference).
Regards,
Andrey
