Abstract In this paper, an analytical model was developed for calculating magnetic field of surface mounted permanent magnet machines (SMPM) with segmented pole. The segmented poles magnetization expression was deduced and the air gap flux density was calculated. Then the cogging torque and back-EMF were calculated. This model can be applied to SMPM with arbitrary pole segment number. Its accuracy was proved by the finite element results. With the analytical model, influences on electromagnetic performance of segment parameters were analyzed to provide a new idea for the design and optimization of SMPM with segmented pole.

Key words： Segmented pole analytical model cogging torque back-EMF harmonic
