ABSTRACT:
A rolling rotor motor/compressor is provided with counterweights for mechanical balancing while permitting radial movement of the rotor/piston. This permits unloading of the compressor such as when there is a liquid slug. The rotor/piston and the counterweights are driven by diametrically opposed windings so that the rotor/piston does not drive the counterweights with attendant power/capacity reductions.
