Abstract: This paper presents results of magnetic characteristic analysis of a magnetic flux concentration type surface magnet motor. Firstly influence of number of the rotor poles on the torque characteristics was examined for fixed stator construction and then some constructions of the permanent magnet array were tested to reduce the cogging torque. Their magnetic flux distributions and torque characteristics were calculated by using the finite element method.

Keywords: CSPMSM, FEM (Finite Element Method), permanent magnet, magnetic arrangement
