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 printed circuit board (PCB) has a tridimensional (3D) dielectric substrate having opposite sides and made of fiber-reinforced polymer. Each side comprises channels and pockets formed by machining a dielectric laminate, and the channels and pockets define a layout for conductive traces and pads of the PCB. The channels and pockets in a same side of the 3D dielectric substrate have a uniform depth. Side walls of the channels and pockets have a draft angle in a range of greater than 0 degrees to about 5 degrees. The conductive traces and pads are formed into the channels and pockets by electrolytic metallization. In addition, the outer surface of conductive traces and pads are flush with the sides of the 3D dielectric substrate.

Abstract: A device has a housing, stators and a rotor with an axis and rotor disks with magnets. Each stator has 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 stators are mechanically coupled to the housing, so the stators react to torque produced by the device. The housing has two end sections and mid-sections where the end sections are mechanically coupled a stator and a ferromagnetic yoke. The mid-sections are mechanically coupled to one or two stators and ferromagnetic yokes. The ferromagnetic yokes are coupled to the stators and to the housing to provide a path for magnetic flux produced by the magnets and a path to conduct heat generated by the stators from the stators to the housing.

Abstract: A device has a housing and rotors rotatably coupled to the housing. Each rotor has a magnet on at least one side of the rotor. Printed circuit board (PCB) stators are located axially between the rotors and coupled to the housing. The PCB stators have layers, and each layer has coils. The number of rotors disks is equal to the number of stators plus one. The stators are interleaved with the rotors. A shaft is coupled to the rotors and the housing. The shaft has a hollow section coupled to a source of a liquid coolant through a rotary connector and to radial channels in the shaft that dispense a liquid coolant between the rotors and PCB stators. The shaft has flanges with different diameters configured to receive the rotors disks with respective matching bore diameters. In addition, the housing has a sump to collect the liquid coolant.
