Abstract: A motor assembly includes a motor, an electric pump to supply oil to the motor, an inverter assembly connected to the motor, and a first wire harness and a second wire harness. The inverter assembly includes an inverter to convert a high-voltage direct current into an alternating current and supply the alternating current to the motor, and a controller to control the inverter and the electric pump. The first wire harness electrically connects an external power supply and the inverter assembly, and passes a low-voltage power supply line. The low-voltage power supply line is, at a branch point, branched into a controller power supply line to supply drive power to the controller and a pump power supply line to supply drive power to the electric pump.

Abstract: A motor unit includes a motor having a motor shaft extending along a first direction, an inverter that supplies electric power to the motor, a housing that supports the motor therein, an inverter case that is fixed to one side of the housing in a second direction orthogonal to the first direction and that houses the inverter, and a plurality of bolts that fasten the housing and the inverter case. The plurality of bolts include a first bolt extending along the first direction, a second bolt extending along the second direction, a third bolt extending along a third direction orthogonal to both the first direction and the second direction, and one or more fourth bolts extending in a fourth direction intersecting all of the first direction, the second direction and the third direction.

Abstract: A motor includes a rotor, a back cover, a housing, and a brush card assembly. The rotor includes a core fixed to a shaft, a coil that magnetizes a core, and a commutator connected to the coil. The back cover includes a back cover bottom surface portion, and a back cover cylindrical portion on an outer periphery of the back cover bottom surface portion to have a cylindrical shape. The brush card assembly includes a brush card bottom surface portion spaced apart from the back cover bottom surface portion in an axial direction through a first gap. The brush card bottom surface holds brushes and includes a nip portion nipped by the back cover and the housing, an outer peripheral wall spaced apart from the back cover cylindrical portion in a radial direction through a second gap, and contact portions contacting the back cover cylindrical portion.
