DEFINITION

Classification: 242/433

On externally toothed core (e.g., motor armature):

(under subclass 430) Subject matter wherein the core on which material is wound includes an outer surface provided with at least one pair of elongated slots which define between them a projection (tooth or pole piece) and comprising a winding mechanism for winding material about the projection for more than 360 degrees.
