ABSTRACT:
A plurality of magnetic pole bodies, provided on a stator of a steering motor, are divided into two electrically independent groups. Each group includes i) six magnetic pole bodies that are arranged in succession and ii) a corresponding number of magnetic pole bodies arranged opposing those six magnetic pole bodies. The two groups vibrate only slightly when operating normally. However, if one of the groups fails, vibration of the stator from elastic deformation in an undulating manner in the circumferential direction will increase, thereby alerting the driver of an abnormality in the steering motor. This increases the likelihood of measures being taken promptly to fix the abnormality in the steering motor, thus improving fail-safe performance.
