A motor unit and a vehicle equipped with the unit according to the invention includes a control unit that selects a switching frequency, that is, a carrier frequency, in accordance with a rotation speed of the motor and a torque required from a motor. When an inverter temperature becomes high, the control unit limits the torque of the motor to suppress further increase in the inverter temperature. A limit value used in restricted operation is determined in accordance with the temperature and the carrier frequency of the inverter.
