Abstract :

Each two years 4 basic IEEE sections in the field of Power Engineering make an open call for Competition for all of the Universities throughout the world expecting the students to develop new energy solutions through their work and innovation, but to be aware of manufacturability and practical use of what they bring as a final prototype. Students World Contest: Future Energy Challenge (http://www.energychallenge.org) is organized in order to bring innovations in the field of Energy Science and to attract more and more students to think on the way of saving the energy. Energy saving is a modern trend in electrical engineering, experiencing a great boom in last decades. Reasons are constant rise of energy prices and awareness of limited energy resources on Earth. Saving electrical energy is of outmost importance since it is the purest form of energy that can be easily converted to any other form. According to some data, electrical drives in the developed world consume between 60% and 70% of all the electric energy produced in these countries. Electric motors impact almost every aspect of modern living. Refrigerators, vacuum cleaners, air conditioners, fans, computer hard drives, automatic car windows, and multitudes of other appliances and devices all use electric motors to convert electrical energy into useful mechanical energy. In addition to running the common place appliances that we use every day, electric motors are also responsible for a very large portion of industrial processes. Electric motors are used at some point in the manufacturing process of nearly every conceivable product that is produced in modern factories. Because of the unlimited number of applications for electric motors, it is not hard to imagine that there are over 700 million motors of various sizes in operation across the world. This enormous number of motors and motor drives has a significant impact on the world because of the amount of power they consume.
