Dear sir,
We are doing a pjt on the speed control of IM using pwm techniques. We have used speed encoder to detect the speed of the IM. the speed encoder we are using is MoC7811. we have searched the net for its details but went in vain. Also we would like to know details of pwm inverter which uses IGBT as its switches. The following is the details of the project.
This project deals with the innovative method of speed control of induction motor using sinusoidal PWM technique using PC. The basic idea behind this project is to compare the speed of the motor with the speed of the reference voltage and if any change, can be corrected by the generation of PWM pulses corresponding to the desired speed. These PWM pulses are then fed to an pulse modulated inverter whose AC output given to the motor controls the speed and runs the motor at the desired speed. The unique feature of this project is the implementation of closed loop system. The advantage of this method is the reduction of harmonics, high starting torque and smooth speed control. Hence this technique can be used for industrial drives and variable speed drives.
Hope u could help us out.
With regards, nimi
