Abstract
An end-leakage flux approximation for turns of coils of a stator winding including at least two poles is developed for an electric motor having a stator with a predetermined number of stator slots within which the turns of the stator winding are distributed according to a predetermined distribution. The approximation is derived by developing a first indication representing a pole-to-pole permeance based on an approximated leakage flux path linking two poles and a second indication representing an individual pole permeance based on an approximated leakage flux path linking one pole and combining the first and second indications to produce an end-turn leakage flux approximation. At least one of the first and second indications is developed in accordance with a discrete representation of the predetermined distribution of the turns of the stator winding. The end-leakage flux approximation may advantageously be developed using a computer-based system.
