43885470, Jun 14, 1983

Filed:

Dec 15, 1980

Appl. No.:

6/216619

Inventors:

John R. Gruber - Cleveland OH

International Classification:

H02K 122

US Classification:

310266

Abstract:

A high current, low voltage generator is constructed of four pairs of rotatably mounted magnetic pole members. The pairs of magnetic pole members are disposed longitudinally along and at angular intervals around a cylindrical air gap region. The angular intervals between adjacent pairs of magnetic pole members alternates between 851/2. degree. and 941/2. degree. A plurality of non-ferrous, conductive segments of a cylindrical, stationary armature are disposed in the air gap region. Rotation of the magnetic pole members around the armature causes the conductive segments to cut the flux lines of the pole pairs inducing electric currents. An electrical circuit connects in series the four segments which are cutting the flux lines of the four pairs of magnetic pole members.

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.
