1. A rotor for a rotary electric machine, a stator of the rotary electric machine being to be placed radially outside the rotor so as to be opposed to the rotor via a gap defined between the rotor and the stator, the rotary electric machine including a rotor shaft, the rotor shaft being fixed to an inner peripheral side of the rotor, the rotor shaft having a shaft refrigerant passage,
the rotor comprising: a rotor core having a plurality of core refrigerant passages, the core refrigerant passage each including:
an inlet passage configured such that a liquid refrigerant flows into the inlet passage from the shaft refrigerant passage;a magnet cooling passage configured such that the liquid refrigerant flows into the magnet cooling passage from the inlet passage, the magnet cooling passage extending in an axial direction; andan outlet passage configured to flow the liquid refrigerant from the magnet cooling passage to the gap, an axial position of the outlet passage in the rotor core being at one place at a central position in the axial direction; and magnets disposed in the rotor core along the axial direction. |
