PEMANFAATAN GENERATOR SINKRON AFWR SEBAGAI MOTOR SINKRON AFWR
Abstract
Generator sinkron Axial Flux Wound Rotor (AFWR) tiga fasa yang telah selesai dirancang bangun dilakukan pengujiannya. Generator ini perlu juga dilakukan pengujian bila dioperasikan sebagai motor sinkron AFWR. Hal ini dilakukan agar dapat dilihat performanya baik sebagai generator maupun sebagai motor. Dengan demikian mesin ini dapat digunakan baik sebagai pembangkit listrik maupun sebagai penggerak mekanik. Pada mesin sinkron ini dilakukan pengujian berbeban. Untuk generator setelah diputar oleh penggerak mula dan diberikan beban listrik kemudian diperoleh hasil pengukurannya. Begitu pula, untuk motor setelah dihubungkan dengan suplai listrik dan diberikan beban mekanik kemudian diperoleh hasil pengukurannya. Pengujian dilakukan pada besaran nominal. Efisiensi generator sinkron AFWR dari hasil pengujian pada celah udara 0,5 mm diperoleh 61,61 % pada beban penuh dengan tegangan eksitasi 10,85 V. Sedangkan efisiensi motor sinkron AFWR dari hasil pengujian pada tegangan terminal 380 V dan tegangan eksitasi 9,53 V diperoleh 73,58 %.
