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.

A high current DC electrical pulse generator comprising: a stator member; a rotor concentrically positioned within said stator and mounted for relative rotation therewith; a main stator winding including two winding sections each being helically wound around said rotor and each being coaxial with said rotor, wherein adjacent ends of said winding sections are electrically connected to a common connection point; a pair of brushes disposed in sliding contact with said rotor, mounted on opposite side of said main stator winding in an axial direction, and electrically connected to opposite ends of said main stator winding; a third brush disposed in sliding contact with said rotor and mounted at an intermediate position on said rotor between said first pair of brushes; means for connecting an external load between said third brush and said common connection point between said winding section such that said load is connected across two branch circuits, each comprising the series connection of one of said winding sections and a portion of said rotor extending between one of said pair of brushes and said third brush; and means for rotating said rotor.
