Abstract

High-speed brushless permanent magnet machines are good for compressor and aerospace applications, etc. since they are conductive to high efficiency, high power density, small size and low weight. This paper presents 3-phase permanent magnet brushless AC Motor designed for the high-speed drives. Especially, we predicted the inverter high frequency pulse width modulation (PWM) switching caused eddy current losses in a permanent magnet brushless dc motor.
