DEFINITION

Classification: 242/432

On internally toothed core (e.g., motor stator):

(under subclass 430) Subject matter wherein the core on which material is wound is provided with a central opening into which at least one projection extends to define a tooth or pole piece and comprising a winding mechanism by which the elongated material is wound about the projection for more than 360 degrees.
