Abstract:
In terms of the serious abrasion of the normal generator bearing,the bearingless permanent magnet synchronous generator (BPMSG) was proposed. Suspension principle and the electric-generation principle of the bearingless permanent magnet synchronous generator were described. Secondly,the formula of the magnetic field energy storage was deduced. Then the mathematical model of the levitation force and electromagnetic torque were established on the basis of the Maxwell Tensor methods. Thirdly, structure of the machine was designed and optimized using parametric analysis mothed,and the correctness of the mathematical model was verified by simulation. Finally,aiming at the common problems of the ordinary permanent magnet synchronous generator under the variable speed and variable load conditions,the suspension forces and the electronic-generation performance were analyzed based on the finite element analysis (FEA). Simulation results show the BPMSM has good feasibility and suspension under the variable speed and variable load conditions. The research results show that the proposed BPMSG can operate steadily and has good static and dynamic performance
