Abstract
The present disclosure provides an example motor system. The motor system includes a steering motor with a first rotor positioned within a first stator. The steering motor is configured to rotate the first rotor about a steering axis. The motor system also includes a traction motor including a second stator positioned within a second rotor. The second rotor includes a traction surface defining a wheel. The traction motor is configured to rotate the second rotor about a rolling axis, and the traction motor is positioned within an opening in the first rotor. The motor system also includes an axle positioned coaxial to the second rotor and coupled to the first rotor such that the traction motor rotates about the steering axis as the steering motor rotates the first rotor about the steering axis.
