ABSTRACT:
A stator for an electric rotating-field induction generator that is much simpler to produce, especially regarding its windings, includes main and auxiliary poles projecting inward pressed or otherwise disposed radially onto the inner side of a yoke and positioned alternately about the circumference, of which the auxiliary poles are not wound, and the main poles are each surrounded by a coil. Each of the wound poles has a groove in the direction of the longitudinal side parallel to the axis along its longitudinal sides to accept coil sections, and these grooves include a trapezoidal cross-section and are enclosed by the non-wound auxiliary poles at the longitudinal-side groove opening. The auxiliary poles are incorporated with the yoke, and the poles are formed as separately-wound laminations that possess force-fit elements parallel to the axis on its joint sides extending toward the yoke whose force-fit elements parallel to the axis correspond to the distance to the division of the wound poles on the inner side of the yoke. The individual coils are easier to wind, and particularly may be wound directly onto the poles to be wound. The non-wound auxiliary poles isolate the coils on the wound poles from one another, and the winding heads do not come into contact with one another because the coils do not cross in the frontal area on both sides of the stator.
