Sculpting Electric Machines for Unidirectional Motion

The objective of this research is to study the improvement in electric machine operation when unidirectional motion is taken into account, since the vast majority of generators and motors rotate in a single direction. The approach is to precisely sculpt the stator and rotor surfaces, thus affecting the electromagnetic field in the air gap so that the production of electromechanical torque is increased. The transformative value of this approach rests in its generality, being applicable to rotating machines of any power rating, material, or type.
