Abstract
The novel rare earth variable flux permanent magnet synchronous motor (PMSM) for electric vehicles is proposed. The structure and magnetic field regulation characteristics are analyzed, the variation of magnetic density, no-load back electromagnetic force and output torque with speed was studied through finite element simulation. The weak magnetic field expansion speed performance of the novel PMSM has been verified through experimental equipment. The adjustable electromagnetic field with running speed on the rare earth PMSM increases the high-speed operation range of vehicle.
期刊介绍：
An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering.
