Increasing the electric motors efficiency in industrial applications

Abstract

Electric Motor Driven Systems (EMDS) account for around 65% of the electricity consumed by EU industry. Switching to energy efficient motor driven systems can save Europe 202TWh in annual electricity consumption. EMDSs are the single largest end-use of electrical energy, consuming more than twice as much as lighting, the next largest end-use. This excess energy consumption represents an unnecessary 79 million t/yr of CO2eq emissions. If CO2 emissions are reduced, it will help in today’s problems regarding climate change. By introducing several energy schemes, costs can be significantly reduced. The aim of this paper is that by conducting case studies on the Maltese manufacturing industry and carry out several experimental tests recommend certain measures to increase the electric motors’ efficiency in industrial applications.
