摘要
设计并试制了一台150kW/900r/min径向叠片磁障式转子双馈无刷电机。利用有限元法对原型电机的磁场分布、空载特性、负载时定子绕组感应电动势和电磁转矩特性等进行了分析计算,并对实验样机作为发电机运行时的几种运行模式进行了实验测试,结果显示制造的原型电机达到了设计的性能指标,在额定运行时电机本体的效率可达95%以上。
A doubly excited brushless machine (DEBM) with radially laminated magnetic barrier rotor (RLMB-rotor) rated at 150kW/900r/min was designed and built. The magnetic fields distribution, the no-load and loaded operation, the induced voltages of the windings and the electromagnetic torque characteristics of the prototype machine were investigated by using the 2D transient finite element analysis model. The results of the experiment validate the design results and all studies show that the prototype RLMB-rotor DEBM is a high-efficiency of 95% generator.
