Abstract

The motor is supported by the panel (22) which can for example be the plate of a watch movement. The bushing (24) has an inner face and an outer face, both of which are cylindrical and coaxial. It is engaged in a hole in the plate (22) and carries the bearings (20) of the rotor (5). The stator pole pieces (3 and 4) have inner faces of cylindrical shape and are positioned by pressing against the outside surface (23) of the bushing (24). The rest position of the rotor is determined by housings made in the coaxial cylindrically arced faces (3a and 4a) of the pole pieces (3 and 4). <IMAGE>
