Abstract
An axial field rotary energy device can include rotors having magnets and an axis of rotation. A stator assembly can be located axially between the rotors. The stator assembly can include PCB panels. Each PCB panel can have layers. Each layer can include coils. Each coil can have radial traces relative to the axis. The radial traces can include non-linear radial traces coupled by arch traces that are transverse to the non-linear radial traces.
