Abstract
A motor control device includes a board that is provided at an end of a motor including winding groups of two systems and controls supply of electric power to the winding group independently for each system. The board includes two areas that are partitioned by a boundary line passing through the center of the motor when viewed in an axial direction of the motor. A power supply terminal connector, an inverter circuit, and a motor terminal connector are sequentially arranged along the boundary line when viewed in the axial direction of the motor. The motor terminal connector is provided such that a straight line perpendicular to a direction in which motor terminals are arranged and the boundary line form an acute angle.
