Abstract
A system for providing torque includes a stator, a rotor, an axle, an endcap, an endbell, and a compliant member. The stator has a first end and a second end opposite the first end with a chamber therein. The rotor is at least partially positioned in the chamber and rotatable relative to the stator about a longitudinal axis. The axle has a first end, a second end opposite the first end, and supports the rotor. The endcap is located at a first end of the stator and adjacent to the first end of the axle, and the endbell is located at the second end of the stator and adjacent to the second end of the axle. The compliant member is positioned relative to the axle between a portion of the rotor and one of the endbell and the endcap.
