Patent ID: 10218235

Abstract:
A rotor includes a rotor core and a permanent magnet. A core refrigerant passage is configured to guide refrigerant supplied from a shaft refrigerant passage to an outer peripheral end of the rotor core. The first refrigerant passage extends from an inner peripheral end of the rotor core to a position inside the permanent magnet. The first refrigerant passage is placed at a position deviating from a q-axis of the rotary electric machine in a circumferential direction. The second refrigerant passage is provided on the q-axis. The second refrigerant passage extends from the outer peripheral end of the rotor core toward an inner peripheral side in the rotor core. The third refrigerant passage configured to provide communication between the first refrigerant passage and the second refrigerant passage, the third refrigerant passage being placed at a position deviating from the second refrigerant passage in a rotor axis direction.
