Abstract
A motor apparatus for a vehicle includes a motor unit, an inverter unit, a case, and a pump. The case has a motor space, an inverter space, and a cooling passage, the motor space accommodating the motor unit, the inverter space accommodating the inverter unit, the cooling passage being configured to let cooling medium flow through the cooling passage to cool the motor unit and the inverter unit. The pump is configured to forward the cooling medium to the cooling passage, and is disposed in a surrounding space within the motor space, the surrounding space being at a periphery of a rotation angle sensor fixed to a shaft of the motor unit.
