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.

Abstract: A system has an axial field rotary energy device with a housing, an axis and a rotor with a shaft, bearings, rotor disks and permanent magnets. A printed circuit board (PCB) stator is between the rotor disks to define an air gap on each side thereof. A variable frequency drive (VFD) assembly has a VFD housing and first pads coupled to inductors to facilitate heat removal from the inductors. A concave cradle is coupled to a ferromagnetic core and has a same contour as an outer surface of the ferromagnetic core. A second pad is coupled to a rectifier module. A third pad is coupled to switching devices and has pins to align the switching devices with the third pad. Standoffs are coupled to the VFD housing to support a first printed circuit board assembly (PCBA). A second PCBA is mounted to a shield plate above the first PCBA.

Abstract: A system can include an axial field rotary energy device with an axis of rotation and a rotor coaxial with the axis and having a shaft, bearings, rotor disks that are coaxial and permanent magnets on each rotor disk. A printed circuit board (PCB) stator is located between the rotor disks to define an air gap on each side of the PCB stator. An enclosure has two enclosure sections with an inspection port. Bearing caps and bearings are mounted to the rotor. A variable frequency drive (VFD) assembly is coupled to the axial field rotary energy device. The VFD has a flexible conduit that extends between the VFD housing and the axial field rotary energy device. The flexible conduit can adapt to different sizes of axial field rotary energy devices.

Abstract: A device has a housing and a rotor with an axis and a rotor disk with a magnet. A cooling plate is coupled to the housing. The cooling plate includes a channel connected to an inlet and an outlet to convey a liquid coolant. A stator is coaxial with the rotor and includes a printed circuit board with conductive layers laminated together with layers of an insulating material. Each conductive layer has coils that can carry electrical current when connected to an external voltage source. The stator is mechanically coupled to the housing, so the stator reacts to torque produced by the device. A ferromagnetic yoke is mechanically and thermally coupled to the stator and to the cooling plate to provide a path for magnetic flux produced by the magnet and a path to conduct heat generated by the stator from the stator to the cooling plate.
