This paper proposes a novel flux switching claw pole machine (FSCPM) with soft magnetic composite (SMC) cores. The proposed FSCPM holds advantages of the conventional flux switching permanent magnet machine (FSPMM) and claw pole machine (CPM) with SMC cores. As permanent magnets are installed between the stator claw pole teeth, FSCPM has good flux concentrating ability, and the air gap flux density can be significantly improved. The torque coefficient of FSCPM is relatively high due to the applied claw pole teeth and global winding. FSCPM is mechanically robust because there are no windings or PMs on its rotor. Moreover, the core loss of FSCPM is relatively low for the SMC material has lower core loss at high frequency compared with silicon steels. The topology and operational principle of FSCPM are explained first. Several main dimensions of the machine are optimized to achieve better performance, based on 3D finite element method (FEM). Furthermore, the rotor skewing technology is adopted to reduce the cogging torque and torque ripple.

一种新型软磁复合磁芯磁通切换爪极电机

本文提出了一种具有软磁复合 (SMC) 磁芯的新型磁通切换爪极电机 (FSCPM)。所提出的 FSCPM 具有传统磁通开关永磁电机 (FSPMM) 和具有 SMC 磁芯的爪极电机 (CPM) 的优点。由于定子爪极齿之间装有永磁体，FSCPM具有良好的磁通集中能力，气隙磁通密度可显着提高。由于应用了爪极齿和全局绕组，FSCPM 的扭矩系数相对较高。FSCPM 在机械上很坚固，因为它的转子上没有绕组或 PM。此外，FSCPM 的磁芯损耗相对较低，因为与硅钢相比，SMC 材料在高频时具有更低的磁芯损耗。首先解释 FSCPM 的拓扑结构和工作原理。基于 3D 有限元方法 (FEM)，优化了机器的几个主要尺寸以实现更好的性能。此外，采用转子偏斜技术，减少齿槽转矩和转矩脉动。
