Abstract
A system and method with a torque response linearly proportional to angular displacement between inner and outer rotors having magnets, forming magnetic poles, to provide a linear magnetic torsional spring with a wide operating region. Multiple rotor sections of magnetic poles in at least one of the inner and outer rotors are provided wherein at least one rotor section of magnets is circumferentially offset by an offset angle from at least one other rotor section of magnets. The magnetic torsional spring can produce linear torque T, where T=+/−k θ, k is the angular spring constant, and θ is the angular displacement. The torque responses from each rotor section can cause a combined torque response to function as the linear magnetic torsional spring. The extended linear portion can provide a useful radial angle of rotation for a linear torque to counteract a spring force applied to the rotor.
