| 中文摘要 | 为了分析采用鼠笼实心转子特殊结构的十二相带整流负载高速异步发电机转子发热情况,需要准确求得电机转子中产生的损耗。采用有限元软件AN SY S对电机进行了二维谐波场及瞬态场的计算,将转子损耗分为定子基波电流产生的基波磁场引起的损耗、定子基波电流产生的齿谐波磁场引起的损耗和齿谐波磁导变化引起的损耗等3部分。仿真计算结果表明:基波磁场损耗较小,47、49次齿谐波磁场损耗较大,而齿谐波磁导变化引起的损耗最大。因此,在高速实心转子异步电机中,齿谐波磁场和齿谐波磁导变化在转子引起的损耗占转子损耗的主要部分。; The rotor losses in a high-speed asynchronous generator were calculated for a thermal analysis of a special rotor made of solid steel combined with a squirrel-cage.The ANSYS finite element software was used to accurately calculate the losses in the rotor through both harmonic and transient 2-D analysis,with the rotor losses divided into three parts as the losses produced by the fundamental mmf,the tooth harmonic mmf,and the tooth harmonic permeance.The simulation results show that the fundamental mmf losses are relatively low,while the tooth harmonic mmf losses are higher and the tooth harmonic permeance losses are the highest. |
