when the motor to be tested rotates along with the rotating shaft of the motor to be tested, the encoder detects the operating parameters of the motor to be tested during operation and sends the operating parameters to the control equipment;
and when the control equipment receives the operation parameters sent by the encoder, judging whether the operation parameters meet preset conditions, and when the operation parameters do not meet the preset conditions, confirming that the motor to be detected is abnormal and generating an alarm signal.
