Abstract
Integrated stator disk devices, systems, and methods for torque generation are provided. The resistive torque-generating device can include an integrated stator disk system including at least one metallic stator disk having a planar disk body, and at least one rotor disposed adjacent to the at least one metallic stator disk such that there are at least two shear areas formed by the at least one metallic stator disk and the at least one rotor; and magneto-rheological material disposed between portions of the at least one metallic stator disk and the at least one rotor. In some embodiments, the rotor(s) is/are a bent rotor(s), thereby providing for increased torque generation while fitting within tight space constraints.
