摘要：PROBLEM TO BE SOLVED: To reduce the number of man-hours and a number of parts used in assembling a brushless motor by simplifying the structure of mounting a printed wiring board mounted with rotational position detecting elements for detecting the rotational position of its rotor. SOLUTION: This entire motor, excepting the inner and outer circumferential surfaces of a stator core 15 on which stator winding 16 is wound, is provided with an insulator 17 formed of synthetic resin, superior in heat resistance and insulation, to insulate the stator core 15. This motor has a printed wiring board 32 provided with a plurality of rotational position detecting elements Hu, Hv, Hw for detecting the rotational positions of permanent magnets placed on the circumference of the rotor 21, and installed on the insulator 17 formed on the stator core 15 in proximity to the coil end portion of the stator winding 16 wound on the stator core 15, in such a manner that the printed wiring board 32 is installed freely detachably.
