Abstract: A frame of an electric motor opens in one end. A heat sink, to which a control substrate is connected, closes an opening of the frame. A stator is positioned on an inner circumferential surface of the frame to be movable in an axis of rotation direction. A fastening bolt penetrates through the heat sink and a motor cover to fasten to the frame, thereby holding the stator between a pressing portion formed on the heat sink and a stepped portion formed on the inner circumferential surface to fix the stator to the frame. A disc spring is interposed between a front bearing that retains a rotor shaft and a spring retainer formed in the heat sink, and the rotor shaft is biased in the axis of rotation direction by a biasing force from the disc spring.

Abstract: A control device for controlling a multi-phase AC motor generating a steering assist torque in an electric power steering device of a vehicle, includes: first and second inverters in first and second systems that output first and second alternating current voltages to first and second multi-phase winding wire sets, respectively; and a control unit that controls a phase difference between the first and second alternating current voltages. The first and second multi-phase winding wire sets provide a stator of the motor, and generate a rotating magnetic field in a rotor. The control unit sets a control range including a reference phase difference, which reduces a specified-order harmonic component, and changes the phase difference within the control range according to a characteristic required of the motor, or so as to cause a fluctuation in the energization of the motor.

Abstract: A housing and a rotary shaft of a motor are formed of non-magnetic material. A soft magnetic member is provided between a first axial end surface of a fixed core and a bearing. The soft magnetic member is provided on the fixed core side relative to the first bearing thereby to suppress magnetic flux leaking to a vicinity of one end part of the rotary shaft by leading the magnetic flux, which is generated from a rotor, to the rotor core through the fixed core and a casing. A magnetic angular position sensor fixed to one end part of the rotary shaft can detect a magnetic angular position of the rotor accurately without being affected by external magnetic field. As a result, noise generated by vibration of the motor can be suppressed.

Abstract: A control unit controls driving of a motor by controlling a first inverter unit and a second inverter unit, specifically by controlling on/off operations of FETs. The control unit functions as an abnormality detection device. The control unit detects a short-circuit abnormality between a first winding set and a second winding set or between the first inverter unit and the second inverter unit, before starting to control driving of the motor, based on phase current values detected by current detectors when a high-side FET of the first inverter unit and a low-side FET of the second inverter unit are turned on.
