发明名称 Electric rotary stepping motor
摘要 An electric rotary stepping motor intended for use in watch movements comprises a stator including a coil support coaxial with the rotor, two compact coils having flat turns, and a field-closing yoke capable of magnetically blocking the rotor in a position enabling it to start up in the desired direction. The motor is made more compact, and its manufacture and assembly are simplified, by designing the coil support with two diametrically opposed arms and the coils as self-supporting elements in which the turns of the windings are joined to one another.
