Abstract
Moteur pas-à-pas du type comportant deux pièces de stator séparées par une fente. Selon l'invention, ce moteur est caractérisé en ce que lesdites pièces de stator sont rendues solidaires d'une plaque de base en étant maintenues écartées de façon fixe, le rotor étant supporté de façon à pouvoir tourner librement entre une plaque de base inférieure et une plaque de base supérieure, en résine, chacune comportant les différents trous de palier pour les rouages d'une horloge, tandis que le stator est pourvu d'une bobine d'excitation montée sur la plaque de base de laquelle lesdites pièces de stator sont solidaires. Montres à quartz.Stepper motor of the type having two stator pieces separated by a slot. According to the invention, this motor is characterized in that said stator parts are made integral with a base plate while being held apart in a fixed manner, the rotor being supported so as to be able to rotate freely between a lower base plate and an upper base plate, made of resin, each having the different bearing holes for the cogs of a clock, while the stator is provided with an excitation coil mounted on the base plate of which said stator parts are united. Quartz watches.
