Abstract:

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.
