Rotating Cylinder Planetary Gear Motor

This paper introduces a new electromechanical motor that incorporates free-spinning magnetized cylinders in the air gap. The motor has some of the features of a magnetic planetary gear in that it amplifies torque but it does so to a significantly higher degree than a conventional planetary gear with passive ferromagnetic elements in the air gap (79% higher). The cylinder motor offers the additional advantage that it eliminates cogging torque. The resulting machine constitutes a new class electromechanical device with the introduction of a freely rotating source of magnetomotive force (MMF) in the air gap that both couples and boosts the torque interaction of the rotor and the stator.
