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