Abstract
An exercise apparatus is mechanically engaged with an electrical current producer so that exercise by a person using the apparatus produces output power which is used at the time of exercising or saved for later use. A motor provides additional drive force by rotating a rotor engaged with the apparatus, the rotor operating by magnetic attraction and repulsion depending on relative positions of permanent magnets on the rotor and electromagnets on a stator. The apparatus is light in weight, low cost to produce and highly durable.
Claims18
An exercise system for generating electrical energy, the system comprising:
- a human exercise apparatus having a mechanical drive engaged directly with a motor mechanically engaged with electricity producers for generating electricity when the exercise apparatus is operated;
- the motor has a pair of stators and a rotor, the rotor positioned between the pair of stators, the rotor having permanent magnets arranged in a pattern within apertures on the rotor, the stators each having electromagnets thereon, the electromagnets arranged in the same pattern as the permanent magnets and are positioned so that magnetic fields of the permanent magnets and the electromagnets interact;
- and
- a switching circuit engaged with the rotor, the circuit providing a sinusoidal output electrical current conducted to the electromagnets, the current switching polarity of the electromagnets corresponding with rotational motion of the rotor and relative positions of the permanent magnets and electromagnets to produce attraction and repulsion forces between the magnets, said forces tending to drive the rotor in a selected direction.
