Abstract
High-speed permanent magnet synchronous machines (HSPMSM) are widely utilized in a variety of industrial applications, such as aerospace and flywheels. The key technical problems, which the development of HSPMSM to high power and high speed, are temperature rise and stress concentration of the rotor. In order to solve the key technical problems, the novel composite magnetic materials are proposed in this paper. The novel composite magnetic materials are composed of magnetic powder, epoxy and carbon fiber. In this paper, 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 HSPMSM are analyzed by finite element method. 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 HSPMSM is laid.
