Abstract: An axial field rotary energy device can include a housing having an axis with an axial direction. A stator assembly can include a plurality of stator panels that are discrete panels from each other. The stators panels can be mechanically and stationarily coupled to the housing. Each stator panel can include a printed circuit board (PCB) having coils that are electrically conductive, each stator panel consists of a single electrical phase. In addition, rotors can be rotatably mounted within the housing on opposite axial ends of the stator assembly. The rotors can be mechanically coupled together with a rotor spacer. Each rotor can include magnets. In addition, in one version, no rotor is disposed between axially adjacent ones of the stator panels.

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 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 method for making a printed circuit board (PCB) with 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.
