PURPOSE:To increase the output of a frequency generator built-in motor without increasing the size by opposing a permanent magnet for a frequency generator and an armature coil end, and positioning a frequency generator detecting coil between the permanent magnet and the coil end. CONSTITUTION:A support 15 which has a flange 16 extending to a space A between a permanent magnet 13 for a frequency generator and the outer peripheral side coil end 6a of an armature coil 6 is provided at a stator 1. A detecting coil 17 for a frequency generator is provided at the flange 16. With this structure, the armature coil 6 can be extended to the peripheral edge of a printed circuit board 5, and the coil side 6a of the coil 6 effective to generator a torque can be increased in length. |
