A novel homopolar machine with at least one electrically conductive rotatable rotor having at least one predetermined current path, a plurality of current channel insulation layers, and a magnetic field source configured to apply a magnetic field penetrating the rotor and intersecting the current channels when the rotor rotates. The current channel insulation layers are configured for anisotropic current flow both to inhibit eddy currents and to channel current flow between predetermined correlated brush pairs. Two particular configurations are proposed, wherein the source of magnetization generates in the rotor two separate zones with magnetic flux in opposite directions, while the current channel insulation layers guide the current consecutively through these so as to generate the same rotation-sense of Lorentz force. |
