Abstract: Modal analysis is a technology for vibration characteristic research. It is the foundation for structural dynamics analysis. Natural frequency is a very important performance in dynamics analysis. Modal characteristics of the Permanent Magnet Linear Synchronous Motor (PMLSM) for ropeless elevator were investigated by finite element method (FEM). FEM models for modal analysis were built for the primary winding, iron core, fixed block, secondary back iron and permanent block by appropriate structure simplificati… Show more

“…When the rotor rotates, the radius deformation of the rotor base is smaller than that of carbon fiber sleeve, excitation windings are separated from the rotor base and fixed by the sleeve to overcome the centrifugal force [15]. Therefore, it makes sense to assume the rotor has no effect on the sleeve, then the carbon fiber sleeve is subjected to itself centrifugal force and stress generated by exciting windings, simultaneously.…”
