PROBLEM TO BE SOLVED: To provide a brushless motor used for disk drive in an apparatus for recording and replaying information contained in a CD-ROM(R/RW), a DVD±(R/RW) and the like, particularly, a motor having stable high-speed performance, by solving problems such as increases in current consumption and variation at high-speed operation. SOLUTION: A through hole is formed penetrating a bracket 4 and a printed circuit board 7 at a position corresponding to the front end of the salient pole between two salient poles 8a adjacent to each other of a stator core 8. Moreover, a relative position between the stator core 8 and a hall element 20 is set so as to be adjustable in a motor operative state through the hole. COPYRIGHT: (C)2006,JPO&NCIPI
