Patent ID: 8110952

Claim:
A rotating electric machine, comprising: a cylindrical stator core; a case member placed on an external circumferential surface of the stator core; coils wound around a plurality of teeth projecting from an inner circumferential surface of the stator core and having coil end portions protruding beyond respective end portions in an axial direction of the stator core; a cooling part to cool the coils by dropping refrigerant onto the coil end portions, the cooling part including a refrigerant path and a guide member, the refrigerant path is defined between the stator core and the case member and causes refrigerant fed from outside into the case member to flow towards the respective coil end portions, the guide member includes substantially Y-shaped channels that split the refrigerant having flowed through the refrigerant path into a first refrigerant flow and a second refrigerant flow; and a temperature detecting element placed in contact with the coil end portion, for detecting coil temperature, wherein the temperature detecting element is placed on the coil end portion at a position corresponding to between the first refrigerant flow and the second refrigerant flow that drops from the guide member toward the coil end portion.
