Abstract
A rotating electric machine includes a rotating shaft, a rotor fixed on the rotating shaft, a stator, a housing, a liquid coolant and a flow direction regulating member. The stator is arranged so that a radially inner peripheral surface of the stator radially faces a radially outer peripheral surface of the rotor through an annular gap formed therebetween. The housing covers both axial ends of the stator and rotatably supports the rotating shaft. The liquid coolant is provided in an internal space formed in the housing to flow into at least part of the annular gap formed between the radially inner peripheral surface of the stator and the radially outer peripheral surface of the rotor. The flow direction regulating member axially faces an axial end face of the rotor through an axial gap formed therebetween and regulates the flow direction of the coolant by means of the axial gap.
