Abstract
An energy conversion system includes rotor, stator and shell components configurations for increasing power efficiency and improving replacement and repair efficiency. The system harvests environmental energy for lower power generation and accounts for non-mechanical sources of rotational resistance within the generator.
Claims15
An alternator comprising:
- a rotor having alternating magnetic and non-magnetic portions on an outward facing circumference thereof;
- a shell component surrounding the outward facing circumference of the rotor and having ferromagnetic portions located opposite the magnetic portions of the outward facing circumference of the rotor, wherein the rotor and the shell component are connected to a rotatable shaft;
- and
- one or more dielectric components wound with copper wire located between the rotor and the shell component;
- wherein the alternator generates power in a range of 2 to 20 watts when the rotatable shaft simultaneously rotates the rotor and the shell component at a rate as low as 1 rpm such that there is no relative motion therebetween.

An alternator comprising:
- a rotor having alternating magnetic and non-magnetic portions on an outward facing circumference thereof, wherein the spacing between the magnetic and non-magnetic portions is approximately equal;
- a shell component surrounding the outward facing circumference of the rotor and having ferromagnetic portions located opposite the magnetic portions of the outward facing circumference of the rotor, wherein the rotor and the shell component are connected to a single rotatable shaft;
- and
- a stator located between the rotor and the shell component, wherein the stator remains stationary while the rotor and shell component rotate simultaneously.
