A high efficiency conductor bar is provided for use in a high flux density environment. The bar is made up of a number of subconductors, each of which consists of strands of small size, insulated copper wire wound into twisted bundles and cables so as to be completely transposed. The subconductors and a tube for coolant fluid are then assembled into a conventionally transposed conductor bar.

Conductor bar for dynamoelectric machines

A homopolar dynamoelectric machine is provided in which the magnetic fields are segmented circumferentially of the machine. Longitudinal field windings are placed in recesses in a cylindrical stator and energized so as to provide radial magnetic fields in polar regions between the field windings. Stator conductors are placed in slots in the polar regions. The rotor carries longitudinal conductors on its surface positioned to cut the radial magnetic fluxes, and current-collecting means are provided at both ends of the machine to make electrical contact with both ends of the rotor conductors. The current-collecting means are connected to the stator conductors to complete the electrical circuit of the machine.

Circumferentially-segmented magnet homopolar dynamoelectric machine

Two parallel magnetic flux paths are provided in a dynamoelectric machine having a superconductive field winding. A first, or main, magnetic flux path includes at least one area of nonferromagnetic or diamagnetic material. A second, or shunt, magnetic flux path prevents the relatively low frequency AC flux present during starting or asynchronous operation of the machine, when used as an AC motor, from penetrating the superconductive winding.
