| Abstract: |
A permanent magnet armature is arranged to be moved initially in spaced proximity to an induction coil connected in an electric circuit including a source of electric potential and an electronic switch such that when the moving magnetic field of the magnet cuts the coil turns the resulting induced current operates the switch momentarily to connect the source of electric potential across the coil. The resulting current flow through the coil produces a magnetic field which is imposed upon the moving magnet such as to accelerate its movement. The magnet may take many forms, such as a spinning top, a motor rotor, a pendulum or other reciprocating member, and others.

First Claim:
Show all 14 claims |
Having now described my invention and the manner in which it may be used, I claim:
1. A novelty electric motor comprising
- a. a stator coil having a stationary magnetic metal core and an electric circuit,
- b. a magnet armature,
- c. means supporting the magnet armature in spaced proximity to and externally of the coil for movement relative to and externally of the coil,
- d. a source of electric potential in the electric circuit of the coil, and
- e. means in said electric circuit operable by coil current induced by movement of the magnet armature for releasably connecting the source of electric potential across the coil momentarily to impose a magnetic field on the magnet armature to accelerate the movement thereof.
