ABSTRACT:
A controlled electric drive (CED) device comprises a pair of rectangular magnetic poles of different polarity arranged adjacent, parallel, and congruent to each other with a relatively narrow gap therebetween, providing an essentially uniform magnetic field between the pole faces. The device further comprises a driver conductor arranged to move freely between the magnetic pole faces in such a manner that an electric current running through the driver conductor will tend to move the conductor out of the magnetic field at right angles to the conductor and to the direction of the magnetic lines of force defining the magnetic field. The device further comprises a controller conductor wound in a flat, essentially rectangular spiral fixed adjacent to, and insulated from, the driver conductor. The controller conductor is so arranged that its longitudinal direction is parallel to the driver conductor, and has first and second portions, with direct current flowing in opposite directions in each of the portions. Further, there is provided a multiplicity of controllers comprising single conductors, multiple conductors, rectangular magnets, shaped magnets, and shaped magnetic gaps. Finally, a plurality of such CED devices can be arranged in various arrays so as to provide for the tracing of complex patterns.
