Abstract

Abstract

For environments with high space utilization rate requirements such as high-speed motors and flywheel energy storage systems, a novel heteropolar radial hybrid magnetic bearing (HRHMB) was proposed. Firstly, the equivalent magnetic circuit model of the new magnetic bearing was established, and the current stiffness, displacement stiffness, and electromagnetic force were obtained by analyzing the magnetic field. The effectiveness was verified by finite element simulation. Then, the stiffness characteristics and space utilization rate of the magnetic bearing were analyzed by comparison with the traditional biased magnetic bearing under the same constraint conditions. Finally, the electromagnetic force coupling between two degrees of freedom in the radial direction of the novel magnetic bearing was studied by finite element simulation and compared with the traditional magnetic bearing. The results show that the volume of the novel magnetic bearing is only 0.87 times that of traditional magnetic bearing under the same bearing capacity and other constraints. At the same time, under the influence of control current and rotor displacement, the relative error value of the electromagnetic force for the novel magnetic bearing is 6.5%, while that for the traditional magnetic bearing is 13.6%. The radial two-degree-of-freedom electromagnetic force coupling of the new magnetic bearing is smaller than that of the traditional magnetic bearing, and the decoupling effect is good.
