Abstract
Motion control using electromagnetic forces. The control of motion in unpowered apparatus and an apparatus driven by electric motors and/or other prime movers utilizes electromagnetic force/torque for control of motion. One objective is to extend the domain of electric motor speed control, traditionally characterized by electronic techniques, to small apparatus such as bubble vibration toys, paper dispensers, toothbrushes and other appliances.
Claims2
A mechanism, with at least one joint having a first link and a second link, with a first magnet coupled to said first link, and a second magnet coupled to said second link, such that the mechanism exhibits stable states corresponding to a position of zero net force between said first and second magnets, which is a Stephenson chain.
