MATHEMATICAL DRIVING MODEL OF THREE PHASE INDUCTION MOTORS IN STATIONARY COORDINATE FRAME

In this paper mathematical analysis for a design three-phase induction motor. Three phase AC induction motors is popular in manufacturing for many reasons. It is quite simple and minimum costs are favorable. It does not have brushes and requires minimum maintenance. In this paper a mathematical development to three-phase AC induction motor by using matrix form. The development applying on model of a real drive of 1.1 kW motor has been achieved. To analysis the axis, three-phase coordinate (A, B, C) to a two axis (β - α) as a (stationary part) representation. Through this drive conversion torque and speed can be controlled easily and control optimization induction motors. MATLAB/ SIMULINK is used to simulate the model of (IM) as tool and for study of characteristics of the motor.
