In a vehicle power steering device, a motor is turned on to rotate in one direction whether a steering wheel is turned clockwise or counterclockwise. A switching mechanism is interposed between a motor armature shaft and an output shaft to change directions of the output shaft rotation relative to the armature shaft rotation in response to turning direction of the steering. The switching mechanism may include electrically controlled coupling/releasing members or mechanically controlled rotation reversing and coupling mechanisms.

Motor for power steering and power steering device using the same

An electric power steering device includes an output shaft connected to a steering mechanism of a steering system for power assisting the steering operation. The EPS includes a motor and a control circuit accommodated in a common motor housing. The motor housing comprises an end frame and a cup-shaped motor case hermetically covering the motor and the control circuit. The end frame is secured to a rack housing accommodating the steering mechanism, so that heat generated by the motor and the control circuit is transmitted to the rack housing.
