Design and Analysis of Flux-concentrated Transverse Flux Permanent Magnet Motor Using 1J22

Due to the decoupling of electromagnetic loads, transverse flux permanent magnet motors have a higher torque density than traditional permanent magnet motors. Materials such as silicon lamination with low saturation magnetization have been unable to provide full performance of transverse flux permanent magnet motors. The ferromagnetic material 1J22 has a saturation magnetization of 2.4T. In order to improve the performance of the motor, the ferromagnetic material 1J22 is used to replace the original silicon lamination. This paper proposes a U-shaped flux-concentrated transverse flux permanent magnet motor (FCTFPM) topology. First, the topology and working principle of the motor are introduced, and The equivalent magnetic circuit model of the motor is established by the magnetic circuit method, and the electromagnetic design formula is derived according to the size equation and empirical formula. Then the no-load characteristics and load characteristics of FCTFPM using ferromagnetic material 1J22 and silicon steel sheet M330-50A are analyzed by finite element method. Finally, a prototype was developed and the no-load characteristic test was carried out. The results show that the theoretical analysis is basically consistent with the test.
