This article presents a new design for setting up high speed synchronous reluctance motors (SynRM) in motor spindle applications for up to 30,000 rpm. The transversal laminated SynRM rotor package is supported by thin steel sheets and a shaft nut to exert a constant axial clamping force. Both, numerical and practical investigations are carried out using FEM-analysis and a test bench for centrifugal force load tests. The objective is to find out at which speed the elastic deformation changes into the plastic deformation. The beginning of plastic deformation is a failure criterion in electric motor construction.High speed machining; Synchronous reluctance drive; Motor spindle
