摘要：
An exact analytical description of the magnetic field in idealized models of surface mounted permanent magnet motors is presented. An approximate dosed form solution is derived therefrom. As to the cogging torque results obtained from measurements, finite element calculations, exact and approximate analytical modeling are compared with each other. The mutual dependency of armature geometry and magnetization pattern as to their influence on the cogging torque is discussed.
