ABSTRACT:
Homopolar generators are provided with a helical field coil disposed around a rotor, wound coaxially with the rotor, and connected in series with sliding electrical contacts on the rotor. The coil of a single rotor machine includes two sections wound so as to increase magnetic flux through the rotor when current is allowed to flow through an external circuit and through the coil and brushes. For a dual counterrotating rotor machine, a single section coil is used to perform the same function.
