Abstract
A motor control device controls a motor including winding groups of two systems. The motor control device includes a board and sensors provided on the board and configured to generate electric signals based on rotation of the motor. The board includes a first area and a second area defined across a boundary line. The first area and the second area include power circuit areas, control circuit areas, signal paths through which the electric signals are transmitted to the control circuit areas, and power paths through which electric power supplied from a power supply is transmitted to the power circuit areas, respectively. The signal paths are provided not to cross the power paths and the power circuit areas when viewed in an axial direction of the motor, respectively.
