Design And Analysis of Standard and Energy-Efficient Three-Phase Induction Motor

Abstract

The concept of green earth also requires lesser energy consumption levels in all walks of life.The Earth's resources are nite and as the world population and aspirations of the developing nations continue to increase, energy consumption in all its forms becomes an ever more important issue. Energy consumed during mining and produc- tion of raw materials together with energy consumed during manufacturing processes all adds to depletion of resources. The energy consumed in machine manufacture is a function of the amount and type of materials used and from this aspect small is beautiful.However, obtaining more output from less material requires a thorough understanding of the processes involved. Speci cally in relation to motors, it in- volves identifying losses and minimizing those which have particular in uence in a given applications.In industry, the major energy consumption is in various mechanical gadgets, which are driven by electric motors. To date the three-phase squirrel cage induction motor has remained an ideal prime mover. It is, therefore, imperative that the energy consumed by such motors be optimized. This m.tech project attempts at understanding/explaining the energy dissipated as "losses" by motors. Then it classi es the losses and indicates the strategies to control and minimize them. All these are done maintaining the sizes and the inter change- ability of energy e cient motors with the standard or existing ones. The justi cation for using higher initial cost energy-e cient motor, compared to standard motors, is the crucial parameter for promulgating energy e cient motors. Using advanced tech- niques, matlab program is developed for standard induction motor and optimized matlab program for energy e cient induction motor will developed by incorporating new design techniques.and and Analysis of above both motors(standard as well as energy e cient) & comparison of various performance parameters
