N2 - High-speed permanent magnet synchronous machines (HSPMSMs) are widely utilized in a variety of industrial applications, such as aerospace and flywheels. The key technical problems, that is, the development of HSPMSMs to high power and high speed, are temperature rise and stress concentration of the rotor. In order to solve the key technical problems, novel composite magnetic materials are proposed in this article. Novel composite magnetic materials are composed of magnetic powder, epoxy, and carbon fiber. In this article, the preparation and molding process of novel composite magnetic materials are proposed. Considering the thermal expansion of epoxy, the analytical model on magnetic properties of novel composite magnetic materials is established. The simulation model of novel composite magnetic materials is determined, and the magnetic properties of magnetic materials with the variation of parameters are analyzed. And the rotor stress and eddy current loss of HSPMSMs are analyzed by the finite-element method (FEM). Finally, the accuracy of the analytical model is verified by the experimental results. The theoretical foundation for the popularization and application of novel composite magnetic materials in HSPMSMs is laid.
