Mechanical design of 3 phase induction electric motor

Abstract

It is undeniable that the world's climate conditions are experiencing a significant quality decrease where the air around our homes, including Jakarta, are not feasible anymore where there are a lot of dangerous Particulate Matter 2.5 in the air that we breathe daily. Not only the air condition, the high demand for processed petroleum such as gasoline and diesel causes Indonesia to import where in 2018 there are 393,000 barrels per day. Of course, the budget spent to meet the fuel needs is not small, and will not decrease for the next few years, given that Indonesia's petroleum stock has also decreased. Based on these problems, Universitas Indonesia is committed to build an environmentally friendly transportation, called Electric Bus. This Electric Bus has prime mover in the form of a 3 phase induction motor. Author on this paper is doing the research to build an electric motor design used on The Bus, so that the motor can produce performance in accordance to the design specifications that is 100 kW, where three motors will be combined to produce 300 kW of power with 1200 Nm of torque. This research focuses on motor construction, as well as the selection of materials where the material used is from Indonesia so that all components of the motor are originally made in Indonesia, with the best quality and specifications. This design has been successfully made resulting a weight of 298 kg and dimensions of 630 mm x 470 mm. The results of this research are expected to be able to electrify The Yellow Buses at Universitas Indonesia.
