文摘This paper presented a comparison of the designing and power loss for electric vehicle motors using various high-efficiency silicon steel sheets. Two types of cost-effective permanent magnet synchronous machines (PMSMs) using neodymium iron boron and new thin-gauge silicon steel sheets were developed. The frequency is a crucial factor impacting the characteristics of silicon steel sheets. The efficiency, torque-speed curve and other experimental results of PMSM motors were described and analyzed.
