SPECIFICATION [0001] This application claims the benefit of provisional application Ser. No. 60/445,884, filed Feb. 7, 2003. BACKGROUND OF THE INVENTION [0002] The present invention relates to an optimized axial field rotary energy device which can be either used as a motor for converting electrical energy to motion or a generator for converting rotary motion to electrical energy. This invention includes a stator formed by stacking a plurality of printed circuit boards wherein the electrical components are arranged for maximum power and efficiency. [0003] Axial air gap brushless motors with layered disk stators are known, such as U.S. Pat. No. 5,789,841 to Wang. The stator winding in Wang utilizes wires interconnected in a wave or lap configuration. These motors were of relatively large size and difficult to manufacture. [0004] Further, axial field electric machines utilizing printed circuit board stators are also known such as shown in U.S. Pat. No. 6,411,002 to Smith et al. [0005] The present invention provides a rotary energy device for operating with multi-phase electrical power. The device is generally flat and relatively thin and provides a motor which can be used with many tools and appliances in use today, such as electric drills, power saws, weed eaters, electric bicycles, washers and dryers. The device according to the present invention is designed to minimize electrical resistance and to minimize eddy and loop current. The electromagnetic inductance is enhanced by minimizing the gap between the rotor magnets and the stator circuits and further since the motor is constructed of printed circuit boards, the manufacturing costs are substantially minimized. SUMMARY OF INVENTION [0006] The present invention provides an axial rotary energy device which is arranged in a multi-phase electric current configuration. The device includes a rotor having a plurality of permanent magnet poles secured thereto and further includes a stator formed by stacking a plurality of printed circuit board working conductor layers together with a plurality of printed circuit board connecting layers. The stator having at least one working conductor layer for each phase of the electric current and at least one connecting conductor layer associated with one working conductor layer. The working conductor layer and the connecting conductor layer each having radial conductors extending from an inner diameter through-hole to an outer diameter through-hole. A plurality of via conductors are provided 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 layers through the through-holes.
