A NOVEL DESIGN AND ANALYSIS OF THREE PHASE INDUCTION MOTOR FROM THE PERSPECTIVE OF SMALL SCALE INDUSTIES TO WORK AS AN INDUCTION MOTOR & A WELDING TRANSFORMER SIMULTANEOUSLY

Abstract

AN induction motor, founds suitable for more than 85% of the industrial applications. The industries in this era of automation may not work very efficiently without the use of induction motors for various processes. The induction motors working on the electromagnetic induction and can also be considered as rotating transformer. Nowadays these motor are used as induction generators. The induction generators are available in the market. Authors have designed and developed and induction motor to work as a motor and the welding transformer. The small industries having lack of space and budget are the beneficiaries of this invention. A perfect balanced 3 phase, welding transforms is not available in market which is very essential to run on small 3 phase alternator (of same rating). Basically the welding transformer is a single phase machine. Only few welding transformers are three phase. The machine developed will work as induction motor and welding transformer simultaneously.
