Rolling rotor motor balancing means

摘要

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.
