Abstract
An improved homopolar machine in which a solid sliding current collector, or brush, is provided for contact with a flat, annular contact surface of a rotor. The flat plane of the contact surface is orthogonal to the rotor's axis of rotation. A plurality of such contact surfaces with corresponding brushes may be employed. Also, several means for actuating the brush into contact with the rotor contact surface are provided.
