Simulation Study on a Novel Transverse Flux Permanent Magnet Motor
With the rapid development of new energy vehicles in China,higher power and torque density requirements for their drive motor technology have been put forward.Therefore,a new type of transverse flux permanent magnet motor is proposed in this article based on the analysis of existing transverse flux motors and stator permanent magnet motors.The permanent magnet and armature windings of the motor are both located on the stator,while the rotor is symmetrically composed of several simple C-shaped iron cores.Based on the structure of the motor,the operating principle of the motor is analyzed,and the relationship between motor power and main dimensions is derived.The expressions for power and torque density are obtained.As an example,the permanent magnet magnetic field distribution,magnetic flux variation law and back electromotive force waveform are simulated and analyzed through finite element method about the 1kW prototype.It has been showed that the windings flux is bipolar and the back electromotive force is approximately sinusoidal.The optimization design and actual prototype manufacturing will be done based on above in future.
