1. A rotary motor apparatus, said apparatus comprising:

  • energy source means for powering said apparatus;

    at least one electromagnet means electrically coupled and responsive to said energy source means for producing controlled magnetic fields; and

    at least one rotatable permanent magnet means having a mechanically coupled shaft for producing rotation of said shaft and converting energy from said energy source means to work, said rotatable permanent magnet means being mechanically disposed proximate said electromagnet means for being magnetically coupled by said controlled magnetic fields for producing said rotation, said electromagnet means comprising a coil member and a fixedly and centrally located magnetic core member with respect to said coil member,said energy source means comprises a first energy source circuit for producing a first magnetic field on said core member and a second energy source circuit for producing a second magnetic field on said core member, said first magnetic field and said second magnetic field coacting to produce a composite magnetic field that effects rotationally cranking said shaft,said first magnetic field comprising a magnetic field that polarizes an end of said core member at a first polarity that is the same as a permanent polarity on a plurality of permanent magnet members of said at least one rotatable permanent magnet means, andsaid second magnetic field comprises a controlled on/off neutralizing magnetic field that neutralizes said first magnetic field during on-states of said second energy source circuit such that said composite magnetic field has no magnetic effect on said at least one rotatable permanent magnet means and that during an off-state facilitates said composite magnetic field having a rotational driving magnetic effect on said at least one rotatable permanent means such that repeated rotational urging of said at least one rotatable permanent magnet means effects said cranking of said crank shaft.
