More Information
Summary:A rotating electric machine includes a shaft connected to a rotor, and a facing member fixed to the shaft and facing an end surface of the rotor via a space. The shaft includes an inner flow path through which a refrigerant flows, and a communication hole that allows the inner flow path to communicate with the space. The facing member includes first blade portions arranged along a circumferential direction. The first blade portion has a first inclined surface inclined with respect to a radial direction such that a distance to the end surface becomes shorter from the inner side in the radial direction toward the outer side in the radial direction. The first inclined surface comes into contact with a refrigerant sprayed from the inner flow path through the communication hole by rotation of the shaft, and sprays the refrigerant toward a coil end.
