[OCCRA]: recomended PWM frequency for CIM motors?

[lonoty]

Hi, our team is trying to create a motor-controller with Mosfet transistors (its not FRC legal but its a nice off season project ). We are going to control the motor-controller with an arduino, but we read that if the frequency is too high the mosfets are going to waste energy switching, and if the frequency is too low the motor might shake and create a buzzing sound. What would be a good frequency to control the motor?
