ABSTRACT:
A switched reluctance machine has a stator or rotor lamination with pole arcs that are wider than necessary to fulfill the starting requirement of producing torque in the required direction at every rotor angle. On this lamination, preferably the rotor lamination, the surface is continuously graded over the entire pole pitch so that the first derivative of air gap length with angle is continuous. This allows control of the harmonics in the torque/angle curve and enables the production of smooth torque as the rotor rotates.
