Claim 17:
18. An axial field rotary energy device, comprising:
a rotor comprising an axis of rotation and a magnet;
a stator assembly coaxial with the rotor, the stator assembly comprising a printed circuit board (PCB) panel having a plurality of PCB layers, each PCB layer comprises coils, each coil comprises only two terminals for electrical connections, one of the two terminals of each coil is coupled to another coil on a different PCB layer with a via to define respective coil pairs, and the coils are coupled to each other only with vias;
the PCB panel consists of a single electrical phase;
the stator assembly comprises discrete, PCB radial segments that are coupled together to form the stator assembly, each PCB radial segment comprises a plurality of PCB panels, each PCB panel comprises pairs of PCB layers, each pair of PCB layers is connected to a selected electrical phase, and the pairs of PCB layers connected to different electrical phases are angularly phase shifted by (360 degrees)/n electrical degrees about the axis relative to each other, where n=a number of electrical phases of the device.
