Abstract
An axial field rotary energy system has a housing and rotors with an axis of rotation that are rotatably coupled to the housing. Each rotor includes a magnet. A stator assembly is located axially between the rotors and coupled to the housing. The stator assembly has a printed circuit board (PCB). The PCB includes a plurality of layers, and each layer has coils. A shaft is coupled to the rotors and the housing. The shaft can dispense a liquid coolant between the rotors and stator assembly. The housing can include a sump to collect the liquid coolant.
