Abstract
A wheel rim generator is provided, including: a wheel rim having a rim, a disc, and an axis of rotation; a bearing having an outer race and an inner race, said inner race is disposed around said rim within the rim width; a rotor configured to rotate with said outer race, has at least one permanent magnet, and a center of gravity being displaced from said axis of rotation; and a stator configured to rotate with said rim, form at least one magnetic circuit with said rotor, and generate electromotive force with one of constant and changing magnetic flux in said at least one magnetic circuit as said wheel rim rotates.

A wheel rim generator, including:
- a wheel rim having a tire bearing rim, a disc, and an axis of rotation;
- a bearing having an outer ring-shaped raceway and an inner ring-shaped raceway, a diameter of said outer ring-shaped raceway being larger than a diameter of said inner ring-shaped raceway, said inner ring-shaped raceway is disposed around and fixed to said tire bearing rim within the rim width, and said outer ring-shaped raceway is configured to rotate relative to said inner ring-shaped raceway without any direct contact in between;
- a rotor configured to rotate with said outer ring-shaped raceway, said rotor has at least one permanent magnet and a center of gravity being displaced from said axis of rotation;
- and
- a stator configured to rotate with said tire bearing rim,
- said stator forms at least one magnetic circuit with said rotor, and generates electromotive force with one of constant and changing magnetic flux in said at least one magnetic circuit as said wheel rim rotates.
