Abstract
Abstract A microgeometric electric field machine includes arrays of conductors formed on or carried by a plurality of substrates. The conductors on a first group of substrates carry electrical charges, with alternate conductors being charged positively and the other conductors being charged negatively. A second group of substrates are interleaved with the first group in close proximity therewith. Also included is a voltage source for successively supplying alternate positive and negative electrical charges to the conductors of the second group of substrates. Effectively a pattern of alternate positively and negatively charged conductors is established for the second group of substrates and these patterns are caused to move, relative to the substrates, along the arrays of conductors to produce "moving" electric force fields which cause one group of substrates to move with respect to the other group. The substrates may be in the form of stacked discs with the conductors being radially positioned thereon, where one group of discs is caused to rotate with respect to another group. Alternatively, the substrates may be in the form of stacked planes with the conductors positioned in parallel thereon, where one group of planes is caused to move linearly with respect to the other group, and in a direction perpendicular to the conductors. The configuration of the substrates, positioning of the conductors, and interleaving of the substrates and conductors could take a variety of forms.
