Nowadays, interior permanent magnet synchronous motors (IPMSMs), generally driven by PWM inverters, are mainly utilized as the traction motors of eco-friendly vehicles. As a result of the carrier harmonics of the input current by PWM inverters, harmonic losses of IPMSMs become higher than those of IPMSMs with ideal current input. This paper discusses the characteristics of the proposed double-layered IPMSM and the conventional single-layered IPMSM with current inputs where the PWM carrier frequencies were set to 5, 10, and 20 kHz, respectively, which reveals the influence of various carrier frequencies on the performance of IPMSMs.
