ROTATING MACHINE DRIVE CONTROL DEVICE AND VEHICLE

摘要

An AC motor drive control device is mounted on a hybrid vehicle (200). The drive control device includes an inverter (14) which drives an AC motor (M1); and a control device (30) which controls the inverter (14) by switching its mode between a first mode and a second mode which can suppress a higher harmonic component of the output current of the inverter more than in the first mode. The control device (30) controls the inverter (14) in the first mode if the magnet temperature of a permanent magnet is lower than a first threshold temperature and controls the inverter (14) in the second mode if the magnet temperature is above the first threshold temperature.
