Patent ID: 11418071

Abstract:
A rotating electrical machine includes a rotor, a stator core, coils, and insulating sheets. A discharge port that discharges coolant is provided on an outer circumferential face of the rotor. The stator core includes an annular or cylindrical yoke, and teeth disposed on an inner circumferential face of the yoke in a circumferential direction with spaces. The stator core is disposed encompassing an outer circumference of the rotor. A slot-wall-face channel is provided on a wall face of the stator core defining a slot, and configured to open as to the slot for the coolant to flow through. The coils are wound on the teeth. The insulating sheet is disposed in the slot and interposed between the stator core and the coil, and is configured with at least part of the slot-wall-face channel open as to the coil.
