Abstract

The voltage source inverter fed interior permanent magnet synchronous motors (IPMSM) have received increasing attention in high performance industrial drive applications. This paper investigates the major design factors which affect the performance of IPMSM used in wide-speed-range constant-power operation. An optimizing design procedure is proposed to improve the torque-speed characteristics and flux-weakening capability. Simulation results from the finite element analysis on the optimized IPMSM structure and experimental results from a 2.2 kW laboratory IPMSM are presented to evaluate the optimizing approach.
