Abstract

The varying industrial requisites demand meticulous control of outcomes of the drives. Induction motors are the most extensively used motors for industrial control and automation. The open loop V/Hz control method is most popular speed control method because of its simplicity. This paper presents a closed loop constant V/Hz control in order to overcome the limitations above and to improve the performance of the drive. This closed loop constant V/Hz control method presents the analysis of speed and torque at different load conditions of a three phase squirrel cage induction motor drive fed with inverter using IGBTS at the power stage with constant volts per hertz control Using PI controller. A 7.5HP, 3-phase, 415v, 50Hz squirrel cage induction is used as a load for inverter. Simulation results of the proposed work are shown in this paper.

Keywords
