Homopolar machine which acts as a direct current (DC) high voltage generator or motor

A homopolar machine for producing high voltage, direct current comprising:

• stator means for supporting the homopolar machine;
• two excitation coils disposed within the stator means for producing magnetic flux so that the homopolar machine can produce direct current when in operation;
• rotor means rotationally disposed within the excitation coils which rotates through the magnetic flux when the homopolar machine is in operation for producing direct current, wherein the rotor means further comprises a disk having a center, a thickness and a periphery;
• and
• a single length, continuous conductor element wrapped repeatedly around the disk radially from the center to the periphery on a first side of the disk, radially from the periphery to the center on a second side of the disk, again radially from the center to the periphery on the first side of the disk, forming a toroidal coil around the disk, each portion of said conductor element extending radially from the center to the periphery on the first side of the disk and radially from the periphery to the center on the second side of the disk forming a conductor segment, such that a plurality of conductor segments are formed wherein successive ones of said plurality of conductor segments are serially electrically connected such that an induced voltage and direct current are produced in the continuous conductor element when the rotor means and conductor segments traverse through the magnetic flux during homopolar machine operation, further comprising an air gap between the rotor means and the two excitation coils, the air gap having a width, and wherein a ratio of a total length of the conductor segments to the width of the air gap is between about 1,000,000 and about 100,000,000.
