Abstract
A rotating electric machine includes a rotor including a rotor core fixed to a shaft, respectively, an end plate provided between the rotor core and a front-side end plate for preventing scattering of a magnet, and an end plate formed in a bowl shape. A passage including a hole penetrating the rotor core and a hole connecting the shaft to the end plate and the bowl-shaped end plate is provided, liquid refrigerant is supplied through the passage, and the liquid refrigerant discharged from the passage is scattered by rotation along an inner peripheral surface of the bowl-shaped end plate so as to reach a space between a coil end surface of a stator and an end surface of an insulator supporting a coil of the stator.
