Introduction

I. INTRODUCTION

Three-phase induction motors are widely used in various applications. They operate on the principle of electromagnetic induction, where a rotating magnetic field is produced by the interaction of three alternating currents. [2] The rotating field induces currents in the rotor, generating torque and causing the motor to rotate. These motors are robust, reliable and efficient, making them the preferred choice are broadly utilized for changing  for powering many devices, from pumps and fans to conveyor system and manufacturing equipment.

They power a wide range of industrial machinery, from pumps and compressors to conveyor systems. Their versatility makes them essential in various applications. Three phase induction motors are highly efficient, converting electrical energy into mechanical energy with minimal energy loss. Three-phase induction motor’s are cost effective to manufacture and maintain, contributing to their widespread use for instance, copper as a choice rather in industrial and commercial setting.

Weather for small applications or large industrial machines, three phase induction motors comes in various sizes, making them scalable for different applications.

A. Three Phase Induction Motors

Three-phase induction motor’s relatively ease to control using various methods such as variable frequency drives (VFDs), enabling precise control of speed and torque in industrial processes. In summary, the three phase induction motor’s versatility, efficiency, reliability, cost effectiveness, powerful performance, stability and ease of control make it a cornerstone in the real world, powering a multitude of essential processes across various industries.

II. CONSTRUCTION OF THREE-PHASE INDUCTION MOTORS

A. Stator

The stator of three-phase induction motor is the stationary part of the induction motor and it is made up of silicon steel and it generates a rotating magnetic field. [1] It consist of three sets of windings spaced 120 degree apart, corresponding to the three phases of AC power supply When AC voltage is applied to these windings, it creates a magnetic field that rotate due to the phase difference between the windings. [1] In summary, the stator responsible producing the rotating magnetic field necessary for the operation of a three phase induction motor. [1]

B. Rotor

The rotor in a three phase induction motor is a crucial component responsible for converting electrical energy into mechanical energy. [1] There are two main types of rotors: squirrel cage and wound rotor. Wound rotor consists of laminated iron core with a three phase winding. The winding is connected to external resistors via slip rings. As the motor starts external resistors are initially in the circuit, providing high resistance and limiting the rotor current. [2] As the motor accelerate, the resistors are gradually short-circuited via the slip rings, reducing the rotor resistance and alloying for higher current and torque.

Conclusion

The implementation of a three-phase induction motor in simulink provides a comprehensive simulation platform to analyze its dynamic behavior, performance, and efficiency. Key insights can be gained into factor like torque characteristics, speed regulation, and response to varying loads. Further analysis may involve fine-tuning control parameters to optimize motor’s performance, making simulink a valuable tool for motor drive system design and evaluation. The accompanying end could be produced using is: 1) This type of programming gives great help to the ideal parameters estimations and calculations. 2) This programming also help to understand the structure procedure of electric motors. 3) Such kind of programming can likewise be utilized for structuring vitality effective machine as a future degree in industries. 4) This programming can likewise be utilized to compute the streamline parameters of electric machine
