Abstract :
The homopolar generator used for speed measurement has no potential drop across the brushes. Consequently, the number of conductors and brushes can be increased so that the generated voltage is at a useful level. Since the homopolar generator is a real dc machine it has the great advantage of having no commutator ripple to limit accuracy.
