MODLING AND SIMULATION OF THREE PHASE INDUCTION MOTOR USING MATLAB

Abstract

The three-phase induction motor, also called an asynchronous motor, is the most commonly used
type of motor in industrial applications. In particular, the squirrel- cage design is the most widely used
electric motor in industrial applications. Electrical engineers and design engineers use normalized values for
the variables. This paper presents dynamic modeling and simulation of 3-phase induction motor using dq
axis transformation of normalized stator and rotor variables in the synchronous reference frame assisted by
matlab/simulink. In this paper a new performances is presented of the three phase induction motor which is
fed from a rectifier inverter system. Steady-state and dynamic performance analysis of the drive is done with
the help of dc and ac mathematical models. MATLAB simulation of this drive is done using equivalent
circuit model of the wound rotor induction motor. This drive is developed in the laboratory for a woundrotor induction motor. Theoretical and experimental performances and simulation results are found as
expected.
