Abstract
The M31D-ZA motor’s method was a method used for operating the 3-phase induction motor (for delta connection standard) on single phase supply that presented by Anthony [1]. This method was very simple and has good characteristics during operation. This research was purposed to make the equivalent circuit model for the M31D-ZA motor’s method, including its formula model. Case studies were focused to calculate the current and power factor of the motor when operating on single phase supply. The research was conducted at the Laboratory of the Electrical Engineering of Institut Teknologi Padang. The object used in this research was the 3-phase induction motor of 1.5 HP, 220V, Δ, 2.75A, 4 poles, 50 Hz, 1400 RPM. The results showed that the equivalent circuit and the formulas given have good accuracy, that is greater than 91% of the current and close to 100% for power factor of the motor if it is compared with the results of experiments in the laboratory.
