Abstract: A control unit includes a drive control unit that controls the on and off operation of the switching elements, and an abnormality determination unit that performs abnormality determination on energization paths to the motor windings. The abnormality determination unit identifies a faulted phase, based on voltage detection values when the switching elements of all the phases are turned off, and identifies a permanent energization fault of the faulted phase, based on at least one of a current detection value when one of the switching elements corresponding to the identified faulted phase is turned on, and a rotational position detection value when one or more of the switching elements corresponding to one or more of normal phases are turned on.

Abstract: An output shaft includes a shaft hole with which a shaft is fittable, rotates by torque output from a motor, and outputs torque to the shaft. A magnet holder includes a holder hole with which the shaft is fittable and is rotatable together with the shaft. A magnet is disposed on the magnet holder. An angle sensor is capable of detecting magnetic flux from the magnet and outputs a signal corresponding to a rotation angle of the magnet holder. A play amount between the shaft and the shaft hole is set to a first predetermined value or larger. A play amount between the shaft and the holder hole is set to a second predetermined value or smaller.

Abstract: A rotary actuator has a connecting member for electrically connecting a terminal to a fixing land. The connecting member is composed of a base portion, a pair of leg portions, a pair of deformation suppressing portions and a pair of holding portions. The terminal is inserted through the base portion. Each of the leg portions extends from the base portion in a radial outward direction. The leg portion is fixed to the land portion by soldering. Each of the deformation suppressing portions extends from an outer-side end of the leg portion toward the terminal. Each of the holding portions extends from an inner-side end toward a forward end of the terminal. The holding portions elastically hold the terminal between them.
