Influência da temperatura ambiente no rendimento dos motores de indução trifásicos

Abstract

The search for improvement in the use of energy sources has shown itself, more and more, to be a necessity for the sustainability of life on the planet. Its rational use, sometimes simply called energy efficiency, is an activity that seeks to improve energy use. In this context, the option for more efficient equipment (those that perform the same work, but with less energy consumption) has been the target of constant efforts in research and development around the world. Electric induction motors are responsible for consuming the largest amount of electric energy in industries, given the strong demand for motive power and due to the versatility, simplicity and efficiency of this type of motor. Among the causes that lead to energy losses in the transformation processes present in the industry, the undesirable production of heat is one of the most present. Thus, this work seeks to investigate the influence of ambient temperature on the efficiency of electric induction motors.
