In this paper,a general and simple simulation model of induction motor is introduced based on its math model of α,β,0 coordinate system and Simulink function of Matlab software.At the same time,by using this simulation model,the analysis of the starting procedure of induction motor is presented to demonstrate its correctness and a series of merits such as shutcut,agility,convenience,intuitionisticness and so on.When using one only need to transfer it to workspace and input proper motor parameters.Therefore,a reliable and convenient simulation model of induction motor is offered for the simulation study in induction motor speed-adjusting and control systems.
