Abstract
This study presents Simulink implementation and mathematical model of squirrel cage induction motor. Induction motor models are generally available in form of d-q model in literature for Simulink simulations. But in this study the model include rotor bars and end-ring near the stator windings. So, the rotor bars and end-ring data (currents, voltages etc.) are accessible and can be investigated. And the rotor bars and end-ring parameters are verification and made optimization. In the solution the number of rotor bars determines the dimension of inductance matrix in the motor model. Because simulated motor has 18 rotor bars, dimension of this matrix is 22x22. Each component of the matrix changes according to motor position. Calculating of inverse of the matrix is necessary for every time period. This process is very difficult in Simulink by using function blocks. In the present study m-file block is used instead of function block. So, solution of mathematical model of squirrel-cage induction motor is implemented by Simulink. The simulation results are given with the model used in start-up condition. The results show that the proposed method is used simulation of the induction motor with squirrel-cage.
