Raja Sekhar Reddy and Niharika 02 01 A polyphase induction motors starting current is five to eight times its rated current when it is started from rest with full voltage impressed Such a motors huge line current is undesirable since it may cause a sudden reduction in the supply circuits voltage and have an unfavorable effect on other connected loads or devices Therefore it is common practice to use auto transformers star delta starters and other devices to start such motors at a lower voltage This work presents a novel technique for starting polyphase induction motors without the need for a primary voltage compensator which lowers the inrush of the starting current The motors appropriately accelerated rotor is then driven in the designated direction of rotation using a crankdriven system After that the motor is tested with its rated voltage applied Through oscillographic recordings obtained from experiments where the results are contrasted with the various beginning approaches this is illustrated with a case study on a threephase fivehorsepower NGEF motor Copyright (c) Journal of Science Engineering Technology and Management Science.
