Design and Strength Optimization of the Carbon Fiber Sleeve of High-Power High-Speed PMSM with Flat Structure
摘要
Abstract
For the design of carbon fiber sleeve of the high-speed permanent magnet synchronous motor with segmented permanent magnets and flat structure, parametric model was proposed to achieve the rapid design of the sleeve. Influences of interference value between sleeve and magnets, radial compressive stress of magnets, and diameter of rotor on the design of sleeve were analyzed. A 3-D finite element model was built to verify the analytical results. In addition, with the temperature rise results of the rotor, it was used to investigate the problem of bending stress of the sleeve caused by pole spacers under different temperature which may result in destruction of the sleeve. The influences of different pole spacer materials on the bending stress of the sleeve were compared. As a result, the bending stress of the sleeve could be greatly decreased by titanium alloy pole spacers and the strength was optimized. A prototype was manufactured and the test was provided.关键词
