Variable Frequency Drive for Three Phase Induction Motor

Abstract

Motor vehicle installations for many years have been considered as backbone for industrial applications. If the induction motor is directly connected to for example main supply it will operate at its limit speed at which it can. On the other side, a lot of applications requires performance at variable parameters. Our main and foremost aim is to increase energy saving by introducing this project. To achieve this ability a variable speed control drive is used along with the load to get variable parameters for example in cars. Indeed it results in the best performance and most efficient delivery of the imported car.[1] Controlling the variable speed frequency provides an easy and efficient way to control the open-loop speed of the motor phase induction. This we applied is known as V/F control. In this paper system the functionality of the V / f drive is summarized. Our strength depends on the square wave produced by the controller and after passing through the circuit to drive the switch using the motor. This paper incorporates Voltage, current and speed test results at different frequencies which show that the driving speed varies depending on the frequency and at the same time the power transmission is controlled to keep the V / f ratio constant.
