Project Title
Closed loop speed control of induction motor using variable frequency drive system.
Project Area of Specialization
Project Summary
A Variable Frequnecy Drive (VFD) is an adjustable device used in electromechanical drive system to control AC motor speed and torque by varying the motor input frequency and voltage. When the mechanical load is applied to induction motor the speed of the motor reduces so as to maintain the constant RPM of the rotor closed loop speed control method is implemented in this project. The variable frequency drive changes the input frequency and hence the speed on varying load.
Project Objectives
Following are the obkectives of this project :
To maintain the constant RPM of the motor on varying load.
To design and implement closed feedback loop.
To control the speed of the motor.
To control the torque of the motor.
To analyze the speed torque variation by designing the model on MATLAB/SIMULINK.
Project Implementation Method
This project uses the variable frequency drive method which changes the input frequency to control the motor speed.
This method is implemented in closed loop so the continuous feedback is taken of the motor speed to maintain constant RPM on variable load.
Benefits of the Project
Can be used in modern electric vehicles.
Higher production throgh tighter process control.
Full control over the machinery.
It can be used in the industries where constant speed is required e.g. textile,cement,sugar industries.
Technical Details of Final Deliverable
Power factor improvemnt of induction motor.
Limiting high starting inrush current.
Lower power consumption and reduced electricity bill.
Better efficiency of the system.
Reduction in harmonics.
Constant RPM irrespective of varying load.
