Methods of manufacturing a stator core

摘要

A method of manufacturing a stator core including stacking a plurality of teeth into a plurality of stacks, said teeth are obtained from a jigsaw pattern of said teeth, said teeth are substantially identical to each other in size, each said tooth is substantially T-shaped via two arms protruding sideways from a leg, said teeth substantially aligning with each other in each said stack; winding said stacks with a plurality of windings; placing said stacks along a perimeter of a polygonal inner surface of a ferromagnetic tube, said inner surface defining an inner space within said tube, each side of said polygonal inner surface corresponding to each said stack and contacting the bases of said legs of each said stack; inserting a shaft into said inner space, the top surfaces of said arms facing said shaft; vacuum encapsulating said inner space in an epoxy resin; removing said shaft.

1. A method of manufacturing a stator core, said method comprising:
stacking a plurality of teeth into a plurality of stacks, said teeth are obtained from a jigsaw pattern of said teeth, said teeth are substantially identical to each other in size, each said tooth is substantially T-shaped via two arms protruding sideways from a leg, said teeth substantially aligning with each other in each said stack; winding said stacks with a plurality of windings; placing said stacks along a perimeter of a polygonal inner surface of a ferromagnetic tube, said inner surface defining an inner space within said tube, each side of said polygonal inner surface corresponding to each said stack and contacting the bases of said legs of each said stack; inserting a shaft into said inner space, the top surfaces of said arms facing said shaft; vacuum encapsulating said inner space in an epoxy resin; and removing said shaft.
