Abstract

A system to generate electricity is disclosed. In a particular embodiment, the system includes a sleeve configured to be secured to an inside of a wheel rim, where the sleeve rotates with a rotation of the wheel rim. A plurality of permanent magnets are mounted to an inside surface of the sleeve, where a polarity of each magnet is opposite to an adjacent magnet. The system also includes an annular core configured to slide into the sleeve and be secured to a portion of a vehicle, where the core is stationary relative to the rotation of the sleeve. Coils are mounted about an outer surface of the annular core in proximity to the plurality of permanent magnets. Accordingly, electrical output is generated as the permanent magnets provide a magnetic flux to the plurality of coils as the sleeve rotates.

Claims
