Determination of slot leakage inductance for three-phase induction motor winding using an analytical method

摘要

The article introduced some expressions for self- and mutual slot leakage inductance of phase windings for the mathematical model of an induction machine in the natural phase coordinate system and for dqO model and in an arbitrary coordinate frame. Calculation of self- and mutual slot leakage inductance have been performed for three-phase double-layer, delta and delta-modified winding connections. Introduced expressions may be useful in the design of windings and in the analysis of dynamic states of AC electrical machines.
