Abstract: A rotary electric machine control device for controlling driving of a rotary electric machine including a plurality of winding sets, includes: a plurality of drive circuits; and a plurality of control units, each of which includes: an individual current limit value calculation unit; a current limit value calculation unit; and a control signal calculation unit. The current limit value calculation unit switches between a current limit value sharing mode and a current limit value non-sharing mode. An electric power steering device includes: the rotary electric machine control device; the rotary electric machine that outputs an assist torque for assisting a steering operation of a steering wheel by a driver; and a power transmission unit that transmits a driving force of the rotary electric machine to a drive target.
