摘要： Provided is an electric motor having improved overall cooling efficiency by enabling a coolant to flow around a stator and around and through a rotor in parallel for the stator and the rotor to allow the stator and the rotor to be cooled in parallel. In the electric motor, after an automatic transmission fluid flowing into a first coolant inflow port (10) passes through a shaft internal flow path and rotor internal flow paths (27), the automatic transmission fluid passes through a coolant exhaust port (20) to flow out of a housing (18). After the automatic transmission fluid flowing into a second coolant inflow port (11) passes through a clearance (31) between the housing (18) and a stator (17) and around coil ends (29) of stator coils (16), the automatic transmission fluid passes through the coolant exhaust port (20) to flow out of the housing (18).
