A proposed method to rotordynamic analysis of a high-speed permanent magnet synchronous machine by retention sleeve

In this paper, the authors present a novel analytical model for rotordynamic analysis of high-speed permanent magnet synchronous machine (HS-PMSM) with retention sleeve. The proposed has fast response, accurate results, and sample formulation, is validated finite-element method (FEM). obtained results show proper accuracy solution approach. significant are: formulation HS-PMSMs can accurately calculate displacement stress solid cylinder rotor at any high speeds temperature rises. Furthermore, concerning changes in ensures requirements rising rotational speeds.
