Abstract: Aiming at the problem of motion control of motor stator winding, according to the motor stator frame structure and the threading method of winding way, a mathematical model was established which could be used to describe the enameled wire waist shape trajectory combining vertical movement of the guide needle and the rotation of the frame. The motion control strategy was presented for arc, ellipse, and minor ends of the waist shape trajectory. The virtual prototype of the motor stator winding machine was established by using the ADAMS software. The efficiency of winding and variation of acceleration under different chord of the both ends were identified through motion simulation. The Acceleration of prototype was tested and theoretical calculated under ellipse chord.  The results indicate that the motion simulation, theoretical calculation and test results are basically consistent. The mathematical model and motion control strategy could address the problem of automatic winding motion control of the motor stator.
