Abstract In this paper, the air gap reluctance in the traditional generalized magnetic circuit method is modified by introducing the complex air gap relative permeance in the calculation. The improved generalized magnetic circuit method can be applied to analyze the no-load air gap magnetic field of the surface-mounted permanent magnet motor, which can consider the influence of magnetic circuit saturation, ferromagnetic material nonlinearity and stator slotting at the same time. The analytical calculation method proposed in this paper is consistent with the finite element simulation results. Experimental tests further verify the effectiveness and accuracy of the improved generalized magnetic circuit method.

Key words： Generalized magnetic circuit method magnetic circuit saturation non-linearity complex relative permeance slotting effect
