Abstract

Induction motor slip ring-type technology has been widely used in industrial as one of crucial electrical components to convert energy mechanically. The construction of this motor is more complex than other standardized induction motors such as squirrel cage. The complexity lies on the connection between the rings and brushes which requires more maintenance. Meanwhile, Squirrel cage motor that is supported by a VSD system allows its user to start motor smoothly and adjusts the speed more efficiently. In this study, we exclusively investigate the possibility of the outdated technology replacement by using squirrel cage standardized induction motor based on its compatibility and the financial perspective as well. To prevent any coming up problems, the selections of new motor and VSD must fulfill the requirement of the existed system. Technical data were collected from customer-s SCADA and nameplates While the financial calculation was made based on payback period. In this case, the payback period is projected within two years that basically depends on operation patterns. According to our point of view, standardized squirrel cage motor potentially replaces the slip ring motor in which squirrel cage motor is not only for having simple operation but also less maintenance and energy cost.
