Motor stator identification and comparison method and system

The invention discloses a motor stator identification and comparison method, which relates to the field of motor stator shrinkage fit, and comprises the following steps: an RFID reader-writer on a conveying track reads and writes an RFID electronic tag, and sends acquired target stator information to be conveyed to a shrinkage fit subsystem and a main cabinet PLC; the shrinkage fit subsystem selects a corresponding target stator according to the target stator information and places the target stator on the AGV; the stator shape detection subsystem acquires actual size information of the targetstator and sends the actual size information to the main cabinet PLC; the shrinkage fit subsystem sends a stator standard library of the standard stator to the main cabinet PLC; the main cabinet PLCcompares the actual size information with a standard stator in a stator standard library, and when the error is smaller than a preset value, the standard stator characteristic parameter with the minimum error is used as target
