Abstract: A motor includes a stator and a rotor having an axis of rotation and a magnet. The stator includes a PCB having PCB panels. Each PCB panel is assigned to one electrical phase. Each PCB panel has a pair of PCB layers. Each PCB layer includes coils, and each coil in each PCB layer of a PCB panel is circumferentially aligned with a corresponding coil in another PCB layer. One coil in one PCB layer is coupled to a corresponding coil in another PCB layer with a via. A number of turns in each coil is a multiple of a number of electrical phases configured for the PCB stator. In addition, the vias that connect two coils in a pair of PCB layers that belong to a same electrical phase do not intersect coils in PCB layers that belong to other electrical phases of the PCB stator.

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.

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.
