The key detection items of servo motor and common problems in servo motor detection

1).Servo motor detection -- cogging torque: Cogging torque is an inherent phenomenon of permanent magnet motor, which can make the motor torque fluctuate and produce vibration and noise. We measure the change of motor torque in a rotation cycle on a special test bench and analyze the distribution of cogging torque.
