US 2026/0055883 A1 · Ring Wheel Generator

Abstract

A modular ring wheel generator designed to convert rotational energy into electrical energy or electrical energy into rotational motion. The invention features a novel three-ring coaxial assembly comprising an outer coil ring, an intermediate magnet ring, and an inner bracket ring. The outer coil ring includes a serpentine coil winding supported by radially aligned spacers, while the magnet ring rotates freely within a ball-bearing raceway housed in the bracket ring. This unique configuration enables efficient electromagnetic induction without direct contact between moving parts. The generator supports dual functionality: in one mode, it powers LED lights mounted on a wheel rim using the wheel's rotation; in another mode, it acts as a motor by converting electrical input into rotational motion. The system is compact, durable, and designed for easy integration into existing wheel assemblies, offering both aesthetic and functional enhancements through its use of persistence of vision lighting effects.

Dependent claims

A ring wheel generator comprising;

a bracket ring configured to fit around a wheel hub on a motor vehicle, said inner bracket ring includes a circular raceway with ball bearings;
a magnet ring coaxially aligned with said inner bracket ring, and configured to fit inside and rotate freely inside said circular raceway in said bracket ring, said magnet ring includes a plurality of disc magnets aligned radially, said disc magnets being aligned with their poles in opposite directions;
a coil ring coaxially aligned with said inner ring and said magnet ring, said coil ring include an inside surface, an outside surface, and an outer perimeter edge, said coil ring includes a continuous, circular coil winding configured to form a continuous serpentine coil winding that extends over and between said magnets on said magnet ring when said magnet ring is positioned in said coil ring;
at least one bracket attached to said bracket ring, said bracket configured to hold said bracket ring in a fixed position between said bracket ring and said coil ring;
and
at least one connector that connects said coil ring to said wheel hub so that said coil ring rotates with said wheel hub;
and,
whereby when said wheel hub is rotated, said coil ring rotates around the magnet ring thereby producing an electric current in the coil winding.
