ABSTRACT:
A stator has a stator base including a printed circuit board provided on a nonmagnetic or weakly magnetic bracket having a shaft support section disposed in the center thereof, a single-phase connected air-cored armature coil provided on the stator base, and a drive circuit member provided on the stator base so as not to overlap the air-cored armature coil. The stator base has a groove hole extending outwardly from a central through hole. A detent torque section extending radially from the center of a detent torque generating member composed of a magnetic body and provided around the shaft support section is accommodated in the groove hole so as to be confined in the stator base in the thickness direction thereof.
