Abstract

PURPOSE: To obtain a simple and yet a highly dimensionally accurate detector by disposing a detecting coil having a flexible winding bobbin facing against to magnetic poles for a revolving speed detection magnetized upon an external peripheral surface of a cylindrical shaped magnet.
CONSTITUTION: At an internal peripheral surface of a cylindrical shaped rotor magnet 1, n poles magnetic pole train to be utilized for a revolving torque generation acting with a stator 4 are magnetized and at an external peripheral surface, together with m poles magnetic pole train are magnetized as for a revolving speed detection, a detecting coil 5 of a ring form facing against to m poles magnetic pole train with constant spacings is disposed. This detecting coil 5 is constituted with a winding bobbin 8 providing projects for windings alternately upon an insulating body of a flexible belt shape and detecting windings wound on winding bobbins and is adhered to an internal peripheral surface of a supporter 6 made either from a non-magnetic material or from a magnetic material provided concentrically with a revolving shaft 3 to support the detecting coil 5 as a ring shape.
