In order to research the operating characteristics of a novel claw pole machine with outer permanent magnet （PM） rotor and special structure, by means of finite element analysis （FEA） software, the simulation model of three-dimensional （3D） electromagnetic field analysis was built for this machine on the basis of analyzing it＇ s structure, material, characteristics and operating mechanism. With the help of two powerful system simulation software ANSYS and CASPOC, the system simulation characteristics was achieved under the conditions of generator and motor by the coupled analysis method of field and circuit. The simulation results show that this kind of machine has characteristics of high power density and torque density, and it has a good operation performance under the conditions of generator or motor.
