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: 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 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.

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.
