Abstract

Induction Motors are the most widely used electric motor, due to its reliability, robust nature and low cost. They are mostly used in household and in the industries. Their industrial application is due to their high torque to volume ratio, ruggedness and low maintenance characteristic which they possess. Induction motor draws a high starting current during starting period which effect on electromagnetic torque, speed and current are greater. The traditional methods of starting includes, Direct On-line(DOL), Star Delta(SD) and Auto-transformer(AT) starting, which control these parameters up to certain limits. This research work is about comparing the starting methods of three phase squirrel cage induction motor using Direct On-Line, Star Delta and Auto-Transformer starter. Squirrel cage induction motor has a peculiar problem which is a problem associated with its initial inrush of current. The method used in this study was “Experimental Method” were experiment was conducted in the laboratory on the various starting methods which was earlier mentioned and Direct On-Line(DOL), Star Delta(SD) and Auto-Transformer (AT)starters was used as the material and MATLAB Simulink was used to observed their output behavior. Results was obtained and presented on tables and on bar-charts were various parameters on the respective machine was compared and the values of “voltage, current, speed and torque were observed and presented on bar-chart. Finally, the study carried out shows that induction motors has a high initial starting current, and over coming this problem, a starting controller has been introduced in phase with the stator of the motor at the point of start to reduce that initial inrush of current.
