Abstract

Scheda was a person who published a method for operating the 3-phase induction motor on singlephase supply in 1985. The method installs a capacitor circuit on the terminal of the motor. So the motor operated like a single phase induction motor. This method only creates some formulas for calculating the capacitor that suitable for operating the 3-phase induction motor on single phase supply. The formulas could not be used for predicting characteristics of the motor in variation speed conditions. Therefore, this research is proposed to create a steady-state equivalent circuit includes its formulas for analyzing the motor on varying speed conditions, especially for power output and efficiency of the motor. The 3-phase induction motor used in this research was the motor of 1.5 HP, 380/220V, Y/?, 2.75/4.7A, 4 poles, 50Hz, 1400 RPM. For validating the formulas, the motor also tested in a laboratory. The results showed that the formulas and equivalent circuit was given had good accuracy when they compared with the results of experiments in the laboratory.
