A DC electric motor system includes a rotor portion having a commutator and a coil winding mounted radially about a shaft, and a stator portion including two rows of spaced permanent magnets about either side of the rotor coil winding. Pick-up coils are mounted about the circumference of the electric motor to pick up energy produced by the change in magnetic flux about the edges of the rotor coil winding. The pick-up coils transfer the collected energy as current for use in charging a battery within an electric vehicle, or the like.
