ABSTRACT:
A stator adapted for mounting adjacent the periphery of a moving machine gear, whereby the gear serves as a rotor in an electric alternator. A pair of elongated pole pieces are mounted in parallel adjacent the gear periphery. Dependent teeth are formed on each of the ends of each pole piece. The ends of the teeth of the pole pieces are separated from the gear tooth tips by a short air gap. The pole pieces are of length such that when the teeth at one end of a pole piece overlie gear tooth tips, the teeth at the opposite end of that pole piece overlie spaces between gear teeth. The pole pieces are displaced longitudinally relative to one another so that when the teeth at one end of one pole piece overlie gear tooth tips, the teeth at the like end of the other pole piece overlie spaces between gear teeth. Magnets are positioned between the pole pieces, one at each end. Gear motion induces electrical potentials in conductor coils wound on the pole pieces.
