Abstract
An electric current generation device includes a rotatable rotor including a magnet assembly establishing a magnetic field proximate the rotor. A stator includes at least one set of coils disposed with respect to the rotor so that rotation of the rotor moves the magnetic field with respect to the coils of the coil set to generate electric current flow in the coil set. The coil set includes an impedance component in communication with the electric current flow to limit the rate of increase of electric current flow generated by the coil set as the rotational speed of the rotor increases. The winding direction of at least one coil with respect to the magnetic field may be opposite the winding direction of the other coils with respect to the magnetic field. Two coil sets may be provided wherein the coils of a first coil set are wound so that the output of the first coil set is out of phase with respect of the output of a second coil set. A rectifier mechanism in operative communication with the first coil set and the second coil set rectifies and combines the output of the first coil set and the output of the second coil set.
