The uses of electric machines are vital today. These are major equipments for engineering, industries, and research scholars as well as in day to day life. In today’s technological advanced and computer based environment use of these machines are limited until they are not upgraded. Thus automation and up gradation are very much required. Here in this paper we are presenting a not much expensiv...
