Abstract
Provided is a motor apparatus in which an increase in its size in a radial direction of a rotation shaft of a motor can be suppressed while securing redundancy of control of driving of the motor. A motor apparatus includes a motor having a rotation shaft, a first control circuit board where a first power circuit and a first control circuit are mounted, and a second control circuit board where a second power circuit and a second control circuit are mounted. The control circuit boards are arranged with an overlapping portion when viewed along an axial direction on an extension line of an axis of the rotation shaft. The overlapping portion intersects the extension line of the rotation shaft of the motor.
