Motor off-line inspection system

The utility model provides a motor offline inspection system, and belongs to the technical field of motors. The problems that a special detection system needs to be designed for detection in existing offline detection, the requirement for continuous repeated testing of a production line cannot be met, and universality is poor are solved. The motor off-line inspection system comprises a driving motor used for dragging a tested motor to rotate, a phase line connection port used for connecting a three-phase line of the tested motor, and an encoder connection port used for connecting an encoder of the tested motor. The oscilloscope is used for collecting three-phase counter electromotive force signals of the detected motor and electric signals of the encoder, the industrial personal computer is used for processing the signals collected by the oscilloscope and displaying a judgment result, and the phase line connecting port and the encoder connecting port are connected with corresponding detection ports of the osc
