Consideration of Space Harmonics in Complex Finite Elements Analysis of Induction Motors with an Air-gap Interface Coupling

摘要

A method for coupling the stator and rotor field in complex magneto dynamic finite element analysis of the induction machine (IM) with considering space harmonics is presented. The coupling scheme is derived from Fourier series of the magnetic potential vector at an air gap artificial interface. A transformation technique is used to introduce the coupling scheme in the saturated time harmonic finite elements model coupled to the electrical circuit equation of the stator. The results obtained are in good accordance with the experimental results.
