Abstract
A direct current generator including a cylindrically shaped shell rotor having a multiplicity of longitudinally aligned conducting segments adapted to be displaced relative to permanent magnet pole pairs for the generation of electrical current. The permanent magnet pole pairs are comprised of magnetic members arranged to form an axial annular air gap. The longitudinally aligned conducting segments of the cylindrically shaped shell rotor are disposed within the axial air gap and are displaced relative to the permanent magnet pole pairs. The relative displacement of the conducting segments of the cylindrically shaped shell rotor in the magnetic flux created by the magnet pole pairs induces electrical current in the conducting segments, which current is communicated by means of commutators to electrical conductors.
