要約(英語): This paper reports that the core loss of a nanocrystalline motor composed of a nanocrystalline magnetic material increases due to a ringing phenomenon, i.e., a damping oscillation in the motor current waveform. The core losses of a nanocrystalline motor is evaluated, when it is driven by an Si-IGBT and by a GaN-FET inverters. The result is compared with that of an NO motor composed of non-oriented electrical steel sheets, which is also driven by the two types of inverters. The core losses of the NO motor decrease with an increase in the carrier frequency. While the core loss of the nanocrystalline motor driven by an Si-IGBT inverter is almost constant, that driven by a GaN-FET inverter significantly increases at higher carrier frequencies. The increase is caused by a ringing in the output current waveform of GaN-FET inverter.
