In this paper, a harmonics analysis of the windings for alternating current machines is made,the general electromagnetic vibration algorithm for the induction motor is studied,and a program also given. Calculation examples are presented,and the results are very close to the measurement. This program will be helpful to the analysis and control of the electromagnetic vibration. The proportional relation between the number of stator slots and that of rotor slots is analyzed in order to reduce the main electromagnetic vibration,and the corresponding calculation method of the number of rotor slots can be used in the motor design.
