Abstract:
Induction motors do not run at synchronous speed; they are generally fixed
speed motors. In industries mechanical loads should not only be driven but should
also be driven at desired speed. Therefore, the need of speed control methods for
induction motor arises. There are various methods of speed control for an
induction motor. In this project reviews on different speed control methods and
their performance based on SPWM inverter, harmonics reduction and speedtorque
characteristics so as to analyse the most effective techniques among them
considering the presence of harmonics.
Thus due to the importance of speed control using VFD drive, that used
scalar V/F as most common technique, this method was studied and investigated
both in simulation and on the field of the industry (Green Food Processing
Industry).
