Bipolar machines-a new class of homopolar motor/generator
First Claim
1. A homopolar motor configured to be driven by a current source comprising:
- at least one electrically conductive rotatable rotor configured to flow a current in a current path when the motor is driven by the current source;
a magnetic field source configured to apply a magnetic field penetrating the rotor and intersecting the current path when the motor is driven by the current source;
current channeling means through the thickness of said rotor provided so as to be parallel to said current path during rotation of said rotor;

Abstract
A novel homopolar machine, i.e. a device comprising at least one electrically conductive rotatable rotor configured to flow a current in a current path and a magnetic field source configured to apply a magnetic field penetrating the rotor and intersecting the current path when the rotor rotates, including the following inventive aspects:
The source of magnetization is one or more bar-type magnet(s) whose geometric and magnetic axes are parallel and normal to the rotation axis, respectively, so that the magnetic field penetrates the rotor in two separate zones with its direction pointing away from the axis in one zone and towards it in the other.
The current path runs along one of the zones and returns in the other, causing a Lorenz force that acts in the same rotational sense in both zones.
The current path is constrained by means of current channeling means in the rotor.
