To improve the accuracy of magnetic circuit calculation of permanent magnet motor, 3 main coefficients analyzed three by 2D electromagnetic filed finite element method. Due to the different rotor position, proposed a new idea about the model of leakage flux coefficient calculation in the paper, and improved the calculating method of current references was improved. Given the equivalent pole arc coef-ficient curves of permanent magnet motor with eccentric poles based on a series of finite element calcula-tions. The results can be used directly in the engineering design.
