摘要： Two inverters (10) provided at respective both ends of open-end windings (8) are appropriately controlled. As control regions (R) of a rotating electrical machine (80), a first speed region (VR1) and a second speed region (VR2) in which the rotational speed of the rotating electrical machine (80) is higher than in the first speed region (VR1) for the same torque are set, and in the second speed region (VR2), a rotating electrical machine control device (1) controls both inverters (10), a first inverter (11) and a second inverter (12), by mixed pulse width modulation control in which control is performed such that a plurality of pulses with different patterns are outputted during a first period (T1) which is a half cycle of electrical angle, and an inactive state continues during a second period (T2) which is the other half cycle.

摘要： A rotor for a rotary electric machine is disclosed. The rotor includes: a rotor core 32 provided with a first magnet hole 321 on an outer side in a radial direction and a second magnet hole 322 on an inner side in the radial direction for each of the magnetic poles; and a plurality of permanent magnets 61, 62 provided in the first magnet hole and the second magnet hole and forming the magnetic poles. The rotor core includes a first section 3211 provided radially outside of the first magnet hole, a second section 3212 extending between the first magnet hole and the second magnet hole and having opposite ends in the circumferential direction that extend to an outer peripheral surface of the rotor core, a third section 3213 extending radially inside of the second magnet hole and having opposite ends in the circumferential direction that extend to the outer peripheral surface of the rotor core, a first bridge portion 41 that connects the second section and the first section and forms a part of the outer peripheral surface of the rotor core, and a second bridge portion 42 that connects the third section and the second section and forms a part of the outer peripheral surface of the rotor core. The first bridge portion is disposed radially inside of the second bridge portion.
