Rotor for rotary electric machine and rotary electric machine

A rotary electric machine, comprising:

• a rotor including:
• a rotor core;
• a shaft having therein a coolant flow passage and a coolant supply port, the coolant flow passage being configured to allow a coolant to flow, and the coolant supply port being configured to supply the coolant to the rotor core;
• and
• a magnet provided in the rotor core, the magnet extending along an axial direction of the rotor core;
• and
• a stator faced to the rotor with a gap,
• wherein the rotor core is fixedly mounted on the shaft, the rotor core is formed by laminating steel plates, the rotor core has a coolant flow path through which the coolant flows,
• the coolant flow path includes a first flow passage and a second flow passage,
• the first flow passage extends along the axial direction near the magnet,
• the second flow passage connects the coolant supply port of the shaft and the first flow passage,
• the first flow passage is formed to penetrate the rotor core by overlapping first slits formed in all of the respective steel plates that constitutes the rotor core,
• the second flow passage is formed by overlapping second slits formed in the steel plates that constitute an axially intermediate region of the rotor core,
• the second slits are different in position that are formed in the respective steel plates
• the first flow passage and the second flow passage join at the axially intermediate region of the rotor core,
• the second flow passage is bifurcated toward the first flow passage, and the second flow passage has a radially symmetrical shape.
