Claim 10:
11. 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) having a plurality of PCB panels that are spaced apart in an axial direction, each PCB panel comprises 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, each PCB panel also 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.
