摘要
A rotating electrical machine includes a rotor and a stator. A first end plate includes a first refrigerant discharge hole which communicates with a second refrigerant flow path hole and supplies refrigerant to a first coil end and a first groove portion which supplies the refrigerant supplied from a refrigerant flow path to a first refrigerant flow path hole and does not supply the refrigerant to the first refrigerant discharge hole and the second refrigerant flow path hole. A second end plate includes a second refrigerant discharge hole which supplies the refrigerant to a second coil end and a second groove portion which supplies the refrigerant supplied from the first refrigerant flow path hole to the second refrigerant flow path hole and supplies the refrigerant to the second refrigerant discharge hole.
說明書
(4) The rotating electrical machine according to (3), in which
the rotor core further includes third refrigerant flow path holes (third refrigerant flow path hole 27) penetrating in the axial direction, and
the second refrigerant discharge holes are provided to overlap with the third refrigerant flow path holes in the circumferential direction.
According to (4), the second refrigerant discharge holes are provided to overlap with the third refrigerant flow path holes provided in the rotor core in the circumferential direction. Therefore, in the circumferential direction, the first to third refrigerant flow path holes can be arranged in a balanced manner inside the rotor core.
