Abstract
An adjustable coupler has a rotary magnet rotor with magnet modules gaps from electroconductive elements on an electroconductive rotor. The magnet modules each have two side-by-side permanent magnets with their respective poles reversed and have a neutral plane between the magnets. The magnet modules can be turned for torque adjustment between a maximum torque position in which the neutral planes intersect at the rotary axis of the coupler, and a minimum torque position at which the magnet modules are turned 90 degrees from the maximum torque position.
