Really? Hmm, I would've thought otherwise. Make the motor large enough and do some electronic trickery to reduce the current X number of seconds after each step coil is energized, or something like that.

Stepping through the rocks would be hard, while smooth rolling would be great. Stepper's are good when you need holding torque, but they are not efficient as you can see. While at mid-to-high RPM you can stall them at unexpected load.

Brian,

Think about a brushless motor as a stepper motor with magnets and a synchronous controller. :)
