Description
Summary:In this paper, coupled problems including structural analysis are studied with respect to permanent magnet assistant-synchronous reluctance motor (PMa-SynRM) for railway traction. The PMa-SynRM is one of alternative motor types considering coasting operation in high speed with back electromotive force induced excessively. The mechanical stress variations are investigated according to material of barrier considering each physical properties including mass density, Young's modulus and Poisson's ratio, and the variation tendency according to properties is presented. The effect of stress in electromagnetic performance and rotor iron loss are also analyzed at each operating point and speed. Finally, the proper option for PMa-SynRM is proposed as a solution of coupled problem.
