Abstract :
This paper investigates the core losses of an interior permanent magnet synchronous motor (IPMSM) under no-load condition. Two experimental tests have been carried out to observe the impact of the pulse-width modulation (PWM) inverter voltage supply on the core losses. The results show that the high frequency harmonic of the voltage supply is responsible for about 22% of the total core losses.
