PURPOSE:To miniaturize the size of the subject motor and improve its operability by a method wherein a wiring board connecting a drive coil is fixedly attached between a yoke and a drive coil, while the wiring board which connects detecting element is installed inside the inner peripheral side of the yoke in two stages toward the first board plate and an axial direction. CONSTITUTION:A ring shaped printed circuit board 16, thin in thickness, is fixedly attached on the inner surface of a disk 8a of a stator's yoke 8 and is pinched between the former and a driving coil 9, and its wiring terminal 16a is led outside through the cutouts 8c, 4a. A ring shaped second printed circuit board 12 for detecting elements is installed in two stages together with the first board 16 to the axial direction along the inner periphery of the yoke 8, fixedly attached to the retainer 11. Lead wires in printed circuit form lead the output side from each element 10, with its lead termianl 12a being protruded outward. Through this configuration, the motor can be miniaturized in size, and workability for wiring works can be improved. |
