A variable flux permanent magnet synchronous motor (VFPMSM) with mechanical device is proposed for field regulation. By introducing the concepts of VFPMSM and flux control with mechanical device, some typical topological structures of VFPMSM are presented, of which the magnetic circuit and operation principles are analyzed. Additionally, the comparisons of comprehensive characteristics of it are obtained. The results show that the displaced-rotors axial VFPMSM has some advantages such as the better flux-weakening ability, less magnetic flux -leakage, higher efficiency and simple manufacturing process comparing with other topologies.
