A new cooling approach to increase efficiency for the induction motor: Vortex tube

Abstract

With the rising demand for energy, concepts such as energy efficiency, energy-efficient devices, and efficiency have grown in importance in recent years. It is well known that a substantial amount of energy produced around the world is consumed in industry, with electric motors accounting for the majority of this consumption. As a result, it is critical to conduct research to improve the efficiency of newly manufactured electric motors in the high efficiency class, as well as electric motors that are still in use because they have not reached the end of their economic lives. The advantages of the proposed system over the conventional fan-cooled system were investigated in this study, which proposed a vortex tube-supported cooling system for cooling the squirrel-caged asynchronous electric motor of the IE3 efficiency class. In this context, an Ansys motor-CAD model of the test engine was created, and a vortex tube-supported experimental setup was built based on the data. As a result of the simulation and experimental studies, the experimental motor's stator winding temperature improved by 68.64%, and its efficiency improved by 1.79% according to the motor nameplate value. The proposed method increased efficiency without requiring any structural changes to the existing electric motor.
