Perancangan Kapasitor Jalan Untuk Mengoperasikan Motor Induksi 3-Fasa Pada Sistem Tenaga 1-Fasa

The method in operation three- phase induction motor on one-phase power supply by using capacitor had developed in success. This method has good response to rotation, less inrush current and increase power factor correction. The characteristic of the motor usually depend on the place and amplitude of the run capacitor used to the motor. Because of that, the purpose of this research is to give us a new method to place and choice the capacitance of run capacitor in operating three-phase induction motor on one phase power supply. The induction motor used was 1,5 kW, 220/380V; /Y; 50 Hz; 6,2/3,6A; 1400 rpm; B class, 0.84 lag. The result show that, the motor can be operated by using of run capacitor 25,9 F on 95,14% of load rating, 1400 rpm, 0.99 leading power factor, and less current harmonic distortion
