A rotor related to the present invention is for a rotary electric machine. The rotor includes a rotor core and magnets. The rotor core has a plurality of core refrigerant passages. The core refrigerant passage each includes an inlet passage, a magnet cooling passage and an outlet passage. The inlet passage is configured such that a liquid refrigerant flows into the inlet passage from a shaft refrigerant passage. The magnet cooling passage is configured such that the liquid refrigerant flows into the magnet cooling passage from the inlet passage. The magnet cooling passage extends in an axial direction. The outlet passage is configured to flow the liquid refrigerant from the magnet cooling passage to a gap. An axial position of the outlet passage in the rotor core is at one place at a central position in the axial direction.
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,
