Comparison of the fractional power LSSR motor with cores made of various magnetic materials

Core optimization, realization of new core shapes and powering the motor at high frequency are some of the reasons to use new materials, those limit the core loss and/or have quasi-isotropic properties in any magnetization direction. In addition, commonly used punching of laminations, causes degradation of a core portions, impairing operating parameters of the motor. In this case, a very good solution may be the use of soft magnetic composite (SMC) materials. The authors deal with the impact of the SMC materials utilization on the motor parameters.
