Abstract: An axial field rotary energy device includes housing sections, each with a ferromagnetic core having teeth. A printed circuit board (PCB) stator assembly is mechanically and thermally coupled to each housing section and has stator windows through which the teeth protrude. An external circumferential channel directs a flow of a liquid coolant. A first lobe is aligned with an adjacent first lobe on an adjacent housing section. The first lobes form a manifold to distribute the liquid coolant to the housing sections. A second lobe is aligned with an adjacent second lobe on the adjacent housing section. The second lobes contain conductors for electrical connections of the PCB stator assemblies. The device also has an air gap between each facing pair of the ferromagnetic cores. A rotor with a rotor disk is axially positioned in a center of each respective air gap and has magnets.

Abstract: A system has an axial field rotary energy device with an axis, a printed circuit board (PCB) stator and a rotor with a rotor shaft and rotor disks having respective permanent magnets (PM). The rotor rotates about the axis relative to the PCB stator. A variable frequency drive (VFD) has VFD components coupled to the axial field rotary energy device. A device enclosure contains the axial field rotary energy device. A VFD enclosure contains the VFD, and the device and VFD enclosures are axially aligned and coupled to each other. A cooling system is integrated within the device and VFD enclosures and cools the axial field rotary energy device and the VFD. The cooling system has a cooling fan located axially outboard of the device and VFD enclosures. The cooling fan circulates an air flow radially and axially relative to the device and VFD enclosures.

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 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.
