Abstract
A stator includes a bracket having a shaft bearing portion at a center, a stator base including a flexible printed wiring board outwardly attached to the shaft bearing portion, single-phase air-armature coils disposed on the stator base, and a drive circuit member disposed on the stator base so as not to overlap with the single-phase air-core armature coils. The bracket has a through hole at the section corresponding to the bottom of the drive circuit member. The stator base is embedded at least partly in the thickness direction in the through hole and fixed using a resin, and a detent torque generation member is contained in, and is no thicker than, the stator base.
