摘要
在Ghosh和Bhadra所建立的电机键合图模型基础上,根据鼠笼式异步电动机原理和结构,应用功率键合图理论,建立了鼠笼式异步电动机的统一扩展键合图模型,使之物理意义更明确。特别是转子导条的键合图模型的建立更具有实际意义。并利用现有键合图仿真软件对Ghosh和Bhadra电机模型与鼠笼式异步电动机模型进行了仿真对比,同时对鼠笼式异步电动机的各种动态特性进行了仿真分析,为鼠笼式异步电动机的优化设计提供了一种新的方法和理论依据。
Based on the motor bond graph established by Ghosh and Bhadra,this article built up a unified expansion bond graph model of squirrel-cage induction motors according to the principle and structure of the motor as well as applied power bond graph theory.This model has brought an even definite physical significance,especially the establishment of bond graph model of the rotor inducing bar has got a great practical sense.A simulation,contrasted with Ghosh and Bhadra motor model and squirrel-cage induction motor model was conducted by taking advantage of existing bond graph simulation software.Meanwhile,simulation analyses for different dynamic characteristics of squirrel-cage induction motors were performed,serving as a new method and theory criteria for their optimal design.
