Abstract
Abstract The center of gravity of the rotor of a rolling rotor motor and the center of gravity of the counterweights are located on diametrically opposite sides of the centerline of the stator. The rotor and counterweights are connected through a plurality of circumferentially spaced links which are pivotable about fixed axes. The rotor and counterweights are able to move radially to change their rotation arm but such movement is transmitted to the other member through the links resulting in a corresponding movement.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
134 words
A rolling rotor motor means comprising: housing means; stator means within said housing means and having an axis and a plurality of selectively activated windings; annular rotor means within said housing means and having a center of gravity and surrounding said stator means so as to coact therewith such that when some of said windings are activated said rotor means is in line contact with said stator means; counterweight means having a center of gravity and movably located within said housing means; and linkage means connecting said rotor means and said counterweight means such that said center of gravity of said rotor means and said center of gravity of said counterweight means are maintained 180 out of phase with respect to said axis of said stator means so as to provide a dynamic balance.
Claim 2
Dependent Claim
134 words
A rolling rotor motor means comprising: housing means; stator means within said housing means and having an axis and a plurality of selectively activated windings; annular rotor means within said housing means and having a center of gravity and surrounding said stator means so as to coact therewith such that when some of said windings are activated said rotor means is in line contact with said stator means; counterweight means having a center of gravity and movably located within said housing means; and linkage means connecting said rotor means and said counterweight means such that said center of gravity of said rotor means and said center of gravity of said counterweight means are maintained 180 out of phase with respect to said axis of said stator means so as to provide a dynamic balance.
