Abstract
A homopolar machine which exhibits reduced wear and prolonged brush life. Current collectors or brushes are mounted so as to maintain substantially constant contact pressure and so that all of them are polarized negative. Brush holders are provided which facilitate the application of precise and constant contact pressure in a region of very high magnetic forces.
