Abstract:
An electric unit is provided with: a motor having a stator and a rotor; a control unit that controls the motor; and a cooling fan that generates cooling wind for cooling the motor and the control unit. The control unit is provided in the upstream of the stator in a cooling flow channel for circulating the cooling wind. The cooling fan is provided to be positioned in the downstream of the motor in the cooling flow channel, the cooling fan generating the cooling wind by drawing air.
