摘要:
There is provided a rotating electric machine capable of preventing a coolant from being retained at an outer surface of a rotor. This rotating electric machine includes a rotation shaft provided so as to be rotatable, a core body secured to the rotation shaft, a permanent magnet embedded in the core body, and an end plate provided so as to be opposed to an axial end surface of the core body. A first coolant channel is formed in the rotation shaft to allow a coolant to flow therethrough. A second coolant channel is formed between the end plate and the axial end surface of the core body to communicate with the first coolant channel. A partition wall that partitions the second coolant channel in a circumferential direction and a path wall that guides the coolant in the second coolant channel toward an outer peripheral edge region of the axial end surface where the permanent magnet is placed are formed inside the second coolant channel.
