  • The servo motor has a rotating sound but does not turn how is it?

Cause: The gear of the reduction gear inside the servo motor is broken, and the servo output shaft will never reach the required position of the potentiometer, so the motor will always make a buzzing sound. The reason may be that the servo motor was impacted by an external force.

 Method: Change a servo motor. If the servo motor is expensive or you want to repair it, turn the servo motor on and replace the broken gear.
