PURPOSE:To miniaturize the size of the subject motor without enlarging the thickness thereof and improve operability by a methoe wherein wiring of a detecting element is made by a printed circuit substrate, while the board is disposed on the yoke of a stator, and wirings are led to the outside through the cutout made on the cylinder of the yoke. CONSTITUTION:A ring type retainer 11 having resilient property is fixedly attached to the disk 8a of the yoke 8 of a stator, and is supporting each detecting element 10 at a plurality of positions located on the periphery of the disk respectively. On the inner peripheral side of the stator's yoke 8, a printed cricuit board 12 being fixed on the retainer 11 is disposed, while the printed wirings are used as connecting wires to lead the output from each detecting element 10. Wiring terminals 12a at the board 12 is so arranged that the lead wires are led toward outside through a cutout 8c, which is a part of the cylinder 8b of the yoke 8, and a outout 4a which is a part of a fixed frame 4. By this construction, miniaturization of the whole apparatus without enlarging the thickness of the motor can be obtained together with the improvement of the operability. |
