Abstract
A torus motor system includes a hollow stator and a rotor which is driven along a rotor path formed within the hollow stator by a magnet system. The rotor operates as a piston within the rotor path to intake and discharge fluid therefrom. The forces on the rotor all tend to center the rotor within the rotor path. The rotor is accelerated away from the inlet port on the magnet system and decelerated as the rotor approaches the discharge port.
