Abstract

In this study, a 2.2 kW super-premium (IE4) class 4-pole three-phase induction motor was designed and developed. We compared this prototype motor with the industrial induction motors sold by leading international companies. We designed and fabricated a stator, an Al rotor, housing, bearing front and rear covers made of Al 6061, a shaft, and a cooling fan. The cooling fan produced with 3D printing technology was assembled on the unload shaft. Following motor assembly, its mechanical performance, such as noise, vibration, wind speed, and efficiency, was analyzed. Compared with the considered international-standard motors, our proposed motor showed superior performance in terms of noise, vibration, and efficiency but not in terms of air gap and wind speed.

Keywords:

Induction motor, Vibration, Noise, Cu rotor, Al rotor
