Abstract
AbstractThis article presents the design studies of a multi‐layer interior permanent magnet synchronous motor (IPMSM) with a radially oriented arc‐shaped hot‐deformed magnet for automotive traction drives. Specifically, by using the IPMSM on a 2010 Prius as a benchmark, we designed an IPM rotor geometry that simultaneously achieves a 20% improvement in both the maximum power and constant output power line with high efficiency while maintaining maximum torque. A prototype of the designed three‐layer IPMSM was manufactured and evaluated. The results of the tests conducted on the prototype are reported and discussed in this article.
