Patent ID: 7109625

Claim:
An axial field rotary energy device having positive and negative polarity, multi-phase electric current terminals comprising: a rotor having a plurality of permanent magnet poles; and a stator having: a plurality of circuit board working conductor layers having at least one working conductor layer for each phase of the electric current, each of said working conductor layers including a pattern of a plurality of radial conductors running between an inner through-hole and an outer through-hole, said inner through-holes being located at an inner diameter of said working conductor layer and said outer through-holes being located at an outer diameter of said working conductor layer; each working layer further having a pair of outer conductors for electrically connecting the positive and negative terminals of one phase of the electric current to selected outer through-holes and a plurality of inner conductors for electrically connecting selected inner through-holes together; a plurality of circuit board connecting conductor layers, at least one of which is associated with each working conductor layer, and each one including a pattern of a plurality of radial conductors running between an inner through-hole and an outer through-hole, said inner through-holes being located at an inner diameter of said connecting conductor layer and said outer through-holes being located at an outer diameter of said connecting conductor layer; each connecting layer further having a plurality of outer conductors for electrically connecting selected outer through-holes together and a plurality of inner connectors for electrically connecting selected inner through-holes together; and a plurality of via conductors, positioned within selected inner and outer through-holes of the working conductor layer and connecting layers, for electrically connecting selected ones of the radial connectors of the connecting conductor layer to selected ones of the radial connectors of the working conductor layer.
