Abstract:
In this electric drive module, a power conversion circuit (12) drives a motor (23-25). Coolant paths (13, 21) cause a refrigerant for cooling the motor and the power conversion circuit to circulate. A housing (40) integrally accommodates the motor and the power conversion circuit and comprises the coolant paths. An inlet (31) to the coolant paths for the refrigerant is provided so as to protrude from the housing. An outlet (32) from the coolant paths for the refrigerant is provided so as to protrude from the housing. A gear device (200) comprises: a speed-reducing unit (210) including a speed reducer connected to a rotating shaft (23) of the motor; and a differential unit (220) including a differential device connected to the output shaft of the speed reducer. The gear device (200) is fixed to the housing. The inlet and the outlet are provided to positions facing the gear device.
