ABSTRACT:
A pair of proximally spaced parallel rotors, the proximal area between the rotors defining a center position containing a center line extending through both rotary axes of the rotors, a plurality of circumferentially spaced magnets of alternating polarity around each rotor and a shielded electromagnet having a pole tip in the center position intercepting the center line, and means for alternating the polarity of the electromagnet as each pair of opposed magnets of like polarity on opposite rotors move through the center position, in order to magnetically draw the magnets approaching the center position and repel the magnets leaving the center position.
