High power density dual-rotor device

摘要

A torsional motor, comprising: a plurality of segments in the shape of a tube comprising an electroactive material with a poling along the length dimension with adjacent segments arranged with their respective polings in opposed directions; a plurality of conductors between the adjacent segments; a first one-way clutch; a second one-way clutch; a first rotor positioned relative to the first one-way clutch such that the angular displacement of the tube in one direction is transmitted by the first one-way clutch to the first rotor; and a second rotor positioned relative to the second one-way clutch such that the angular displacement of the tube in one direction is transmitted by the second one-way clutch to the second rotor.
