Design And Construction Of A Single Phase Power Supply For A Three Phase Induction Motor

ABSTRACT

These 3 phase motor is supplied with 3 three-phase AC supply and is widely used in ships for heavier loads. This research is purposed to established a new method is simple and good to operate the three phase induction motor on single phase power by using capacitor. The object used in this research was three phase induction motor that has the standard of 2 HP, 440 volt, Wye connection, 2 Pole, 50 Hz, 3000 RPM, 3.08 Amp. The result of this research showed that the method could work well to control the motor to operate properly to load 85% of the full load. In general the motor has better performance when operating on single phase power system in all load cases (low at high load). The motor could operate with power factor close to unity, higher speed and better efficiency. The motor operated with higher current harmonic distortion with low loads but lower current harmonic distortion at high loads. There for it is very good to operate the motor at high load up to 85% of its full load.
