摘要:
?针对普通发电机轴承磨损严重的问题,提出一种无轴承永磁同步发电机。首先分析了无轴承永磁同步发电机的悬浮原理和发电原理; 其次,推导了感应电压表达式,利用麦克斯韦张量法建立悬浮力和电磁转矩的数学模型并验证其正确性; 再次,运用参数化分析法设计并优化了发电机结构,仿真结果验证了发电机具有良好的悬浮力和电磁性能; 另外,将设计的样机进行试验,验证了该发电机具有良好的动态性能; 最后针对发电机常见的变速、变负载的问题,基于有限元仿真分析了其对发电机运行性能的影响。仿真结果说明该发电机在特殊工况下具有良好的悬浮性能。研究表明提出的新型发电机具有良好的动静态性能可以稳定运行。
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
