Application of VFD For Three Phase Induction Motor

This paper is about the various applications of Variable frequency drive (VFD) on a three-phase induction motor. In this, we carry out different on load and no-load test on a three-phase induction motor. Variable Frequency Drive (VFD) is an electronic device that is used to change utility power source to variable frequency. Variable Frequency Drive (VFD) can be used to control the speed of a three-phase induction motor. A load of an Induction Motor is not constant it varies according to the load requirement. So, speed must be changed as per increasing or decreasing the load. The main aim of the project is to control the speed of a three-phase induction motor with energy-saving. Hence to maintain the speed supply voltage and frequency must be varied accordingly. There are several ways to define Variable Frequency Drive (VFD). This paper is intended to provide a basic understanding of Variable Frequency Drive (VFD) terms, Variable Frequency Drive (VFD) Operation.
