Abstract: A rotary electric device control device controls driving of a rotary electric device including a plurality of winding sets. The rotary electric device control device includes: a plurality of drive circuits; and a plurality of control units. The control units include signal output units for outputting control signals to the drive circuits corresponding to the control units, respectively, and communicate with each other. The control units include: one master control unit; and at least one slave control unit. An electric power steering device includes: a rotary electric device control device; the rotary electric device 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 device to a drive target.

Abstract: A rotary electric device control device for controlling driving of a rotary electric device including a plurality of winding sets, includes: a plurality of drive circuits; and a plurality of control units that include signal output units for outputting control signals to the drive circuits corresponding to the control units, respectively. The one of the control units generates a control signal according to a command value calculated by each system, a host system detection value relating to a detection value of a host system, and another system detection value relating to another detection value of another system. An electric power steering device includes: the rotary electric device control device; the rotary electric device 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 device to a drive target.

Abstract: In a rotation detecting apparatus, each of first and second sensor elements measures rotation of a detection target. A circuit module includes first and second rotational angle calculators each calculating, based on a corresponding one of a first measurement value of the first sensor element and a second measurement value of the second sensor element, a rotational angle of the detection target. The circuit module includes first and second rotation number calculators each calculating, based on the corresponding one of the first measurement value and the second measurement value, a rotation number of the detection target. The circuit module includes first and second communicators each outputting, to a controller, a rotational angle signal based on the rotational angle and a rotation number signal based on the rotation number. A package packages the first and second sensor elements, and is mounted to a circuit board separately from the controller.
