Abstract:In this paper, the distribution regularity of harmonic waves is investigated. On the basis of it, an universal approach for calculating differential leakage of AC electric machines, regardless of winding types, single-phase or three-phase, regular or non-regular, integral-slot or fractional-slot, symmetrical or asymmetrical, is attained after corresponding mathematical reasoning. The novel approach distinguishes itself in exact result, universal property, and high calculation speed. In the end of this paper, examples are taken to illustrate the correctness and practicability of the novel approach. Besides, the error of conventional approaches is specified by contrast.
Keywords:AC machines  harmonic analysis  differential leakage
