Abstract

An electrical generator is formed with at least one nonconductive cylinder mounted for rotation about an axis and containing four pairs of permanent magnets, longitudinally spaced within the cylinder and angularly offset from each other in a helical array. Each of the magnets in each pair is radially disposed in the cylinder opposite the other and separated from the other at the cylinder axis with like poles facing each other. An electrical secondary is provided within the magnetic field of the magnets in the cylinder. A ring magnet is oriented with an axis parallel to the cylinder axis and is relatively movable therealong. The magnetic fields acting between the ring magnet and the magnets in the cylinder rotates the cylinder to induce electrical current in the generator secondary.
