Abstract

A motor apparatus for a vehicle includes a motor unit (20), an inverter unit (30), a case (40), and a pump (50). The case (40) has a motor space (61) accommodating the motor unit (20), two or more inverter spaces (62, 63) each accommodating the inverter unit (30), and a cooling passage (70). The inverter spaces (62, 63) are provided adjacent to the motor space (61) via respective walls (41a, 41b), and each accommodating at least one of the capacitor (32), the power converter (31), and the control circuit (33). The cooling passage (70) includes a first cooling part (71) configured to cool the power converter (31) and a second cooling part (72) configured to cool the capacitor (32). A length (L1) of the cooling passage (70) from a discharging part (51) of the pump (50) to the first cooling part (71) is made shorter than a length (L2) of the cooling passage (70) from the discharging part (51) to the second cooling part (72).
