Abstract: A motor control apparatus includes a motor, a motor controller, and a connection line. The motor is mounted to a vehicle and has a metal housing. The motor controller is separately provided with the motor, includes a housing and a circuit portion, is connected to the motor through a load line, and drives the motor by a drive current transmitted through the load line. A ground line of the circuit portion is connected to a body of the vehicle as a body earth. The connection line directly connects the metal housing of the motor and the circuit portion of the motor controller without through the housing of the motor controller.
