ABSTRACT:
A solenoidal homopolar dynamoelectric machine is provided with inner and outer field coils positioned on opposite sides of a current collecting zone of a rotor which is mounted for rotation with respect to a stator structure. An additional field shaping coil or a tilted brush box current collector is used to conduct current in a circumferential direction near the current collection zone of the rotor to reduce the radial components of magnetic flux in the current collection zone. This reduces circulating currents in the brush assembly.
