The stator 52 includes a stator core 91 and a coil 92 wound around a plurality of slots formed in the stator core 91. The coil 92 includes a first coil end 98a which protrudes in the axial direction from one end surface 91a side of the stator core 91 and a second coil end 98b which protrudes in the axial direction from the other end surface 91b side of the stator core 91. The first coil end 98a is located on the radially outer side of the first end plate 40a and the second coil end 98b is located on the radially outer side of the second end plate 40b. Therefore, the refrigerant discharged from the first refrigerant discharge hole 42a of the first end plate 40a is supplied to the first coil end 98a and the refrigerant discharged from the second refrigerant discharge hole 42b of the second end plate 40b is supplied to the second coil end 98b.
[Cooling Action]
Next, the cooling action of the rotating electrical machine 50 will be described.
In the rotating electrical machine 50 of the embodiment, the refrigerant pumped by a refrigerant pump (not illustrated) is supplied to the rotor shaft 10 through a circulation path. The refrigerant supplied to the refrigerant flow path 11 is supplied to the refrigerant flow path 12 which passes through the rotor shaft 10 in the radial direction.
