Abstract
Aiming at the influence of eccentric faults on the performance of synchronous reluctance motor (SynRM), the distribution characteristics and change rules of dynamic electromagnetic stress before and after eccentric faults of SynRM were studied. A dynamic electromagnetic stress calculation model combining eccentric fault finite element method and Maxwell tensor method is established under the influence of magnetic saturation. The dynamic electromagnetic stress before and after the eccentric fault of the rotor surface, rotor magnetic ribs, and stator tooth wall are calculated, and the differences in the electromagnetic stress distribution are analyzed in detail. The analysis methods and results of electromagnetic stress provide a reference for the design and structure optimization of SynRM, and it also presents a theoretical guarantee for the smooth and orderly operation of SynRM.
