Abstract
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.
