Technical and Economic Analysis of Replacement Slip Ring Motor Into Standard Squirrel Cage Induction Motor and VSD Hapsari Dewi, Chairul Hudaya Universitas Indonesia Jalan Kampus UI, Kukusan, Beji, Kukusan, Beji, Kota Depok, Jawa Barat 16424 chairul.hudaya[at]gmail.com hapsamarwa[at]gmail.com 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 In this study, we exclusively investigate the possibility of the outdated technology replacement by using squirrel cage standardized induction motor based on its compatibility and the financial perspective as well.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.

This research was conducted to obtain high efficiency absorption power on various wind speed. The VAWT mechanical design is based on systematic calculations with a height of 150cm and a diameter of 120cm. NACA0015 airfoil with calculations in the NACA airfoil database obtained blade length of 15.892cm and width of 1.905cm. The electronic control on this system, Arduino mega controller, has input from an anemometer sensor, and rotary encoder sensor. While, the output is servo motors for 3 blade. A microprocessor control unit is programmed to control the adjustment of blade angle of attack. The angle of attack is defined by wind speed, angular speed of VAWT, and a defined TSR (Tip Speed Ratio). The angle of attack control method is PID (Proportional-Integral-Derivative) algorithm. By setting the TSR value constantly at 3.5-4, the angle of attack will be adapted even on any various wind speed. As a result, the maximum power absorption will be obtained on various wind speed. This system can increase power efficiency of VAWT up to 35-40%.
