A magnetic spring includes a plurality of spaced-apart stationary circumferentially magnetized segments disposed along a circle about an axis to define a first plurality of spaced-apart gaps, and a plurality of spaced-apart moveable circumferentially magnetized segments disposed along the circle to define a second plurality of spaced-apart gaps. Each of the plurality of moveable magnetized segments is axially slidable within a respective one of the first plurality of gaps defined by the plurality of stationary magnetized segments. Significant applications of the magnetic spring in an actuator of a ventricle assist device (VAD) or a total artificial heart (TAH) in which stored energy in the magnetic spring is used to reduce motor power loses of an actuator during a power stroke of the VAD or TAH. |
