Abstract

PURPOSE: To provide a thin type setp motor of good conversion efficiency by so arraying the yokes sandwiching the flat thin type coil of the setp motor from both sides as to become mutually in V-type or U-type.
CONSTITUTION: The yokes 7, 8 forming the magnetic path of a rotor 11 and the yokes 6, 5 which are respectively fixed by means of adhesive agents or the like and sandwich both surfaces of a flat, thin type coil 4 are so arrayed as to become mutually V-type or U-type. This configuration prevents the leakage of the magnetic flux formed by the coil 4 between the yokes 5, 6 which do not mutually oppose. Hence, the step motor of thin type of good conversion efficiency may be provided and the reduction in the thickness of the watch achieved.
