ROTARY ELECTRIC MACHINE

WIPO Patent Application WO/2023/074705

A1

Disclosed is a rotary electric machine which is equipped with: a stator which has a teeth section and has a coil wound around the teeth section; a rotor provided coaxially to the stator with a gap interposed therebetween in the radial direction, and having a hollow shaft and a core member which is secured so as to be coaxial to the shaft and around which a field winding is wound; and a coolant channel structure which is connected to a pump for transporting a liquid coolant. Therein, the field winding includes a coil turn section positioned in the axial-direction end section of the rotor, the coolant channel structure includes a first coolant channel which is connected to the interior of the shaft, the first coolant channel extends from the shaft so as to pass more through the inside in the axial direction than through the coil turn section toward the outside in the radial direction, and the first coolant channel has a discharge port which faces the stator in the radial direction and is located in the radially outside end section.
