Abstract
A rotary electric machine including a rotor including a rotor core; permanent magnets to be embedded in the rotor core; and a one end-side end plate configured to support one end side of the rotor core. The rotor core has rotor refrigerant passages through which refrigerant for cooling the permanent magnets flows in an axial direction of the shaft. The one end-side end plate has an end plate refrigerant passage communicating with the rotor refrigerant passages. The end plate refrigerant passage has refrigerant reservoirs, each projecting to an outer side in a radial direction of the shaft.
