Modelling of the three-phase induction motor using SIMULINK

Abstract

This paper describes a generalized simulation model of the three-phase induction motor using the SIMULINK software package of MATLAB. The model is based on two-axis theory of revolving frame transformation. The model takes power source and load torque as inputs and gives speed and electromagnetic torque as outputs. Internal resistance of the power supply and magnetic saturation of the motor may also be accounted for.
