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 molding or 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 at least about 5 degrees to at least about 15 degrees.

Abstract: An axial field rotary energy device can include a housing and a rotor coupled to the housing. The rotor can include an axis of rotation and a rotor disk having a magnet. The device can include a stator that is coaxial with the rotor. The stator can include a printed circuit board having 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 coaxial with the rotor and stator. The ferromagnetic yoke can be mechanically and thermally coupled to the stator and the housing 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 housing.

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 molding 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: An axial field rotary energy device or system includes an axis, a PCB stator and rotors having respective permanent magnets. The rotors rotate about the axis relative to the PCB stator. A variable frequency drive (VFD) having VFD components are coupled to the axial field rotary energy device. An enclosure contains the axial field rotary energy device and the VFD, such that the axial field rotary device and the VFD are integrated together within the enclosure. In addition, a cooling system is integrated with the enclosure to cool the axial field rotary energy device and the VFD.
