中小型电机定子侧结构件对损耗影响的时步有限元分析及降耗措施
Time-stepping Finite Element Analysis of Influence of Stator Structural Components on Losses of Small and Middle Motors and Loss Reduction
摘要
Abstract
In order to study the influence of stator structural components on motor losses, such as cramp slot, cramp, press ring and motor base, the completed time-stepping finite element model （T-S FEM）, considering the above components, was established for AC motors. Meanwhile, for cast aluminum motor base, the manual outer boundary was determined based on the steady state FEM and truncation method. Then, the following contents was studied systematically by means of this model： 1） influence of cramp slot on losses of motor with different poles; 2） influence of cramp and press rings with different resistivity on motor losses; 3） influence of different motor base on losses, namely, cast iron, cast aluminum and cast steel. Further, aiming at stator structural components, some loss reducing measures were presented, as well as, taking an Y132S-4, 5.5 kW asynchronous motor as an example, the losses with the measures are computed and compared with the former ones, it is shown that the total no-load loss is reduced about 16W, which is 0.3% of rated power. The achievement in this paper can provide theory and technical supports for loss reducing in stator structural components during premium motor development.关键词
