Study on Novel Claw Pole Automobile Generator with Outer PM Rotor

This paper introduces a novel permanent magnet claw pole generator (PMCPG) with outside rotor. Its structure and operation principle are described. The magnetic field distribution and induction EMF of the PMCPG are calculated by ANSYS software. The calculation formula of inductance parameter has been also given in this paper. By means of two powerful simulation tools, the ANSYS and CASPOC software, the operation characteristic of the PMCPG with and without load is simulated on the basis of coupling of magnetic field and electric circuit. The simulation result shows that the PMCPG has well operation performance and is suitable to be used in vehicle.
