Abstract
An adjustable coupler has a group of magnet rotors with permanent magnets separated by air gaps from non-ferrous conductor rotors presented by a group of conductor rotors. One of the rotors is mounted to its shaft via a slidable hub. The hub and the rotor attached thereto rotate with the shaft, but are movable lengthwise along the shaft. The air gaps are adjusted by axial movement of the hub and one of the groups relative to the other to vary the slip of the coupler and control the load speed under varying load conditions.
