Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
212 words
An electric machine stator comprising: a ferromagnetic carrier of a preDetermined shape; a plurality of uniform ferromagnetic teeth affixed to one surface of said ferromagnetic carrier, spaced from one another, and lying in a predetermined pattern; a plurality of printed circuit conductors on first and second opposite surfaces of each of said uniform teeth, said conductors being substantially linear and substantially parallel to one another; a plurality of metallic conductive paths embedded in each of said uniform teeth extending from said first to said second opposite surface, with each conductive path electrically uniting one end of one printed circuit conductor on said first surface to one end of one printed circuit conductor on said second surface, said printed circuit conductors and said metallic conductive paths defining a continuous winding extending from one surface of each of said uniform teeth to an opposite surface thereof; first and second metallic terminals in each of said uniform teeth, connected to respective ends of the continuous winding, and extending out of one surface; connector means through which the respective terminals of each of said teeth extend; and printed circuit conductors on the surface of said connector means opposite from said uniform teeth, for connecting the respective terminals of said uniform teeth in a predetermined electrical pattern.
Claim 2
Dependent Claim
