发明名称 Stepper motor for electric watch, method of manufacturing this motor and electric watch equipped with this motor.
摘要 The present invention relates to a stepper motor for an electric watch, comprising a rotor, a stator, a coil and an electrical circuit. This motor is characterised in that the core 14 of the coil 15 of the stator 10 includes a link ear 16 arranged to permit its mechanical fixing and its magnetic coupling to the pole piece 11, in that the coil holder 20 of the coil 15 is self-supporting, and in that the free end 21 of the core 14 is laid flat against the other pole piece 12 by means of a piece 22 made of synthetic material and a tightening screw 23. <IMAGE>
