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.

The actual displacement of the screw compressor is affected by those factors

1) Leakage. There is no contact between the rotors and between the rotor and the housing during operation, and a certain gap is maintained, so gas leakage will occur. When the pressure increased gas leaks to the suction pipe and the sucking groove through the gap, the exhaust volume will be reduced.
