The magnetic circuit method was used with four different magnetic flux leakage paths of the permanent magnet motor taken into account to eliminate the inaccuracy due to the motor structure changes by determining the integral flux leakage region according to the motor structure size,with a small calculation amount. Simulation results with the magnetic circuit and the finite element methods show the accuracy of the proposed method with changing arc coefficient,air-gap length and magnet height. The method without complex finite element numerical calculation is convenient and suitable for the permanent magnet machine design and optimization.Read More
