The project is designed to provide a soft and smooth start to a 3 phase induction motor. The three phase induction motor during the initial starting condition draws up much higher current than its capacity and the motor instantly reaches the full speed. This results in a mechanical jerk and high electrical stress on the windings of the motor.

Description

The project is designed to provide a soft and smooth start to a 3 phase induction motor. The three phase induction motor during the initial starting condition draws up much higher current than its capacity and the motor instantly reaches the full speed. This results in a mechanical jerk and high electrical stress on the windings of the motor. Sometimes the windings may get burnt. The induction motor should start smoothly and gradually catch up the speed for a safer operation. This project is designed to give a soft start to the induction motor based on the SCR firing triggered by heavily delayed firing angle during starting and then gradually reducing the delay till it reaches zero voltage triggering. This results in low voltage during start and then gradually to full voltage. Thus the motor starts slowly and then slowly picks up to full speed.

This project consists of a six anti-parallel SCRs, two for each phase, the output of which is connected to a set of lamps representing the coils of a 3 phase induction motor. The charging and discharging of capacitors is interfaced to comparators resulting in delayed firing pulses during start and then gradually reducing the delay till the motor runs at full speed. Output from the comparators is fed through opto-isolators to trigger the SCRs.

Further the project can be enhanced by using IGBTs in place of SCRs with PWM control to reduce harmonic distortions often encountered in SCR triggering mechanism.

SOFT START OF THREE PHASE INDUCTION MOTOR

Soft start of three phase induction motor is project of the last year engineering project, BE final year engineering project. This project is used for the BE last year engineering department students. This project is last year electrical and core electrical engineering department students.

This project is last year electrical engineering department students. This project is last year core electrical engineering department students.

Soft start of three phase induction motoris the project of a good price for the electrical engineering projects. It is a very comparative engineering project. It is a very good BE final year project. This project is three phase induction motor based project and idea for electrical projects.

The engineering projects give in the ELECTROSAL HI- TECH PVT.LTD. The best place for the degree and diploma final year engineering projects as well as for electrical students’ final year for the golden opportunity.

Soft start of three phase induction motoris an easy project and idea for the electrical degree and diploma base students and 100% output is done.
