Abstract

PURPOSE:To keep the feature of flat disk type while obtaining accurate revolution-speed signals by compactly incorporating the principal section of a revolution-speed detecting means, CONSTITUTION:With the disk type brushless motor M-1, a main body is formed by pressing in and fixing a discoid soft steel plate 2 to the opening end of the lower surface of a flat cuppy box body 1, and a shaft 5 is axially supported rotatably at the central section by bearings 3, 4. A discoid yoke 9 made of a magnetic substance is hung and mounted to the shaft 5, and a field magnet 6 is fixed to one surface of the yoke 9. A frame-shaped armature coil 7 and a generating coil 10 are flatly wound and formed, and a positional detecting element 8 such as a Hall element is arranged at the frame-shaped armature coil 7 side.
