A new theory of development of force and torque in variable reluctance stepping motors

Abstract

AImtrtet. This paper pre~nts a new theory of force and torque production in doubly slotted magnetic structures encountered in variable reluctance machines. This general theory is applicable to any point on the B-H curve of iron. It is calmbl© of explaining all known phenomena including those for which satisfactory explanations are not available in existing theories. It enables optimimtion of all dimensions defining tim rotor 8eometry to be carried out. It thus lays a sound theoretical basis for designing variable reluctance machines.
