Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/079719
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a rotating electric machine in which an increase in the pressure loss of a refrigerant flowing through a cooling flow path can be suppressed. A refrigerant flow path of the stator 3 of the rotating electric machine 1 of the present invention has: a first refrigerant flow path 11 through which a refrigerant flows in the circumferential direction; second refrigerant flow paths 12A, 12B through which the refrigerant flows in the axial direction; third refrigerant flow paths 13A, 13B through which the refrigerant flows in the circumferential direction; and a refrigerant supply flow path 10. The refrigerant supply flow path 10 first supplies the refrigerant to the first refrigerant flow path 11. The first refrigerant flow path 11, the second refrigerant flow path 12, and the third refrigerant flow path 13 are configured so that the refrigerant supplied to the first refrigerant flow path 11 flows from one second refrigerant flow path 12A to one third refrigerant flow path 13A and the refrigerant supplied to the first refrigerant flow path 11 flows from the other second refrigerant flow path 12B to the other third refrigerant flow path 13B.
