Abstract
A disclosed electrical generator includes a housing, an actuator, a rotatable member, a stator, a rotor, an electrical circuit, and a current controller. The actuator is movable relative to the housing and the rotatable member is also rotatable relative to the housing. The rotatable member cooperates with the actuator such that movement of the actuator causes rotation of the rotatable member. The stator is fixed relative to the housing and the rotor receives rotational kinetic energy from the rotatable member. Movement of the rotor relative to the stator generates electromagnetic induction in the rotor and/or the stator which produces a three-phase alternating current. The electrical circuit includes a rectifier that converts the alternating current to a direct current. The current controller regulates the direct current to thereby generate a fixed constant direct current.
