Pure homopolar generator
A pure homopolar generator
is an electric generator not requiring brushes or electronics or semiconductor parts to convert torque into direct current. In other words, this homopolar generator only requires theoretical homogeneous or actual homogenized magnetic field to be able to produce direct current. The theory of PHG is explained using Maxwell's equations. This term unifies all devices that work in line with this definition. PHG can be represented by patents, which should also work the other way round: US5977684, PV2011-293 application number 2011-293, AU5801890.
