PROBLEM TO BE SOLVED: To raise the reliability by materializing the positional constitution of an IC for detecting the position of a rotor, and a driver for supplying each coil of a stator with drive power by simple constitution. SOLUTION: For this driver, hole IC's (H1-H6), which detect the position of a permanent magnet 11 by grasping the magnetic flux of the permanent magnet 12, are supported outside in the direction of rotation axis against the coil 9 wound on the salient pole 3c of a stator 3, and also six pieces of IC's are arranged by 60 deg. in electric angle at the center in circumferential direction of specified salient poles (3cu, 3cv, and 3cw), and the signal output of the hole IC's (H1-H6) is reflected directly on the switching of the polarity of the drive current to be applied to the coil 9. |
