PURPOSE:To miniaturize the size of the subject motor and improve operability by a method wherein a resilient printed circuit board having printed wirings to connect detecting element is fixedly attached to a cylinder of a stator's yoke and a protrusion for connecting supporting member is formed into a cylindrical shape. CONSTITUTION:A ring shape retainer member made of synthetic resin and the like is fixedly attached to a disk 8a of a stator's yoke 8, which supports each of a detecting element 10 at a plurality of positions located on the periphery thereof. A printed circuit board 12 for detecting element made of resilient and conductive material is wound in cylindrical form and fixedly attached along the inner surface of the circular periphery 8 of the yoke 8, while a pair of protrusions 12b for supporting and connecting element 10 is bent inwardly and orthogonally from the cylinder, and is formed in parallel with the disk 8a, being fixedly attached to the supporting member. To the board 12, connecting wires are extended in printed circuit form from each of the elements 11, while terminals 12a are led outside through a cutout 8c being provided on the cylinder 8b and a cutout 4c at the cylinder of a fixed frame 4. |
