DC electric rotating machine using hall effect material

An electric rotating machine, comprising a rotor mounted for rotation, said rotor adapted to create a rotor magnetic field;

• a plurality of slabs of material exhibiting a Hall effect positioned in side-by-side configuration within the rotor magnetic field, each slab having a width, a length, and a thickness, with opposing edge faces extending along the length of the slab defining the thickness thereof and opposing end faces extending along the width of the slab defining the thickness thereof, and wherein each of the slabs is curved along its length to extend circumferentially around at least a portion of the rotor;
• magnetic material, with a relative permeability greater than unity, extending circumferentially around the plurality of slabs to close a flux loop for the magnetic field created by the rotor;
• means electrically interconnecting the plurality of slabs so that current can flow from end to end in each of the slabs;
• a plurality of conductor means spaced along the length of and associated with each slab interconnecting respective opposing edge faces of that slab;
• and means for causing a primary current flow through the material exhibiting the Hall effect in a primary direction normal to the rotor magnetic field to cause the material exhibiting the Hall effect to generate a Hall effect current in the material exhibiting the Hall effect in a direction normal to the primary direction of said primary current flow and also normal to the rotor magnetic field.

An electric rotating machine, comprising a rotor mounted for rotation, said rotor adapted to create a rotor magnetic field;

• means to produce torque on the rotor;
• material exhibiting a Hall effect positioned within the rotor magnetic field;
• means for rotating the rotor to induce a primary current to flow through the material exhibiting the Hall effect in a primary direction normal to the rotor magnetic field;
• conductor means coupled to the material exhibiting the Hall effect, said conductor means, together with the Hall effect material to which it is coupled, forming a plurality of loops to carry primary current induced in the material exhibiting the Hall effect without said induced current passing through separate stator coils;
• and output means coupled to the material exhibiting a Hall effect to carry to an outside electrical load Hall effect current generated in the material exhibiting the Hal effect in a direction normal to the primary direction of primary current flow and also normal to the rotor magnetic field, wherein said induced primary flowing in the material exhibiting the Hall interacting with the rotor magnetic field is the means to produce torque on the rotor and the machine operates as the generator.
