Abstract: A lightweight superconducting machine provides a coil support shell having a polygonal outer surface facilitating the use of flat electrical coils better adapted to superconducting temperatures. An improved mounting of spokes between the rotor and shell provides for a straight spoke extent reducing stress concentration facilitated by a ball joint termination of the spoke and in-line orientation of a tightening mechanism.

Abstract: A lightweight superconducting machine suitable for aerospace applications provides a wound-field rotor suspended from a driveshaft by insulating tensile spokes. The resultant reduction in heat transmission allows a cryocooler positioned centrally within the rotor to cool the machine coils through radially conducting straps.
Abstract: A slotless electric motor provides a ferromagnetic yoke that includes laminations of a ferromagnetic material interspersed with a high thermal conductivity nonferromagnetic material to greatly reduce the thermal resistance of this yoke. A thermally conductive coil form provides heat conduction paths on three sides of the coils to this yoke which may in turn attach to a heatsink providing fins that vary angularly along the axis and radius of the heatsink.
Abstract: A high-efficiency, high specific power electric motor/generator for aircraft use provides a cantilevered external rotor removed from load thrust and vibration by an isolator and hearing set between the rotor and stator reducing material demands and weight otherwise required for stiffness to preserve close rotor/stator proximity.
Abstract: A slotless electric motor provides a phase change material that may communicate thermally through the sides of coils directly attached to the outer circumference of the central stator. A control system modeling the motor allows effective operation for short durations.
