Abstract

PURPOSE:To simplify a construction and assembly with the speed detection mechanism made into one unit with the drive coil. CONSTITUTION:A drive coil 17 is provided on a stator yoke 14, and a rotor yoke 10, with a magnet 12 provided thereon, is installed to a capstan shaft 1 which is supported by a bearing shaft 3. The drive coil 17 and speed detection coil 19 are provided in one unit on a coil base plate 16. Whereby a tolerance for eccentricity between the capstan shaft and the speed detection coil can be improved to a great extent with the work of assembly simply enabled.
