LAVET MOTOR AND METHOD OF ASSEMBLY

摘要

A b s t r a c t The invention relates to an electric watch, wherein wheels of the watch movement and the rotor of a step motor are arranged between the facing inner sides of the metal frame and the plastic frame and are mounted in bearing holes of these frames or base plates. In accordance with the invention, the plastic frame has adjacent to the bearing hole of the rotor a substantially vertical web bent at an angle in the direction of the metal frame and penetrating the air gap between the rotor and the stator of the step motor, while the stator with the associated exciter coil is mounted on the outer side of the plastic frame. This construction enables assembly of the rotor without the occurrence of disturbing magnetic interaction between rotor and stator.
