Abstract
Motor induksi tiga fasa merupakan motor yang telah banyak digunakan di pabrik-pabrik besar pada umumnya, selain efisien dari segi harga, perawatannyapun tidak begitu sulit. Namun tidak menutup kemungkinan saat berada di lapangan, motor induksi tersebut mengalami kerusakan, salah satunya yaitu terjadinya ketidak-seimbangan pada air gap atau celah udara. Sehingga dapat menyebabkan kondisi jarak celah udara antara rotor dan stator tidak seragam atau serempak dimana kondisi ini disebut eccentricity. Untuk mencegah terjadinya kerusakan yang berkelanjutan, penilitian ini dilakukan agar dapat mendeteksi kesalahan atau kerusakan secara dini. Sehingga Peneliti mencoba menganalisis efek pembebanan dan tegangan tidak seimbang dengan melihat spektrum arus stator pada motor induksi tiga fasa dengan kondisi ketidak-seimbangan air gap dan difokuskan pada kondisi static eccentricity. Hasil dari data ini akan diolah dengan menggunakan metode yang ada yaitu Fast Fourier Transform (FFT). Untuk curret signature dilihat pada saat kondisi steady state. Hasil dari percobaan menunjukkan bahwa dengan adanya efek pembebanan tingkat persentase keberhasilan deteksi sebesar 67%. Sedangkan untuk tegangan tidak seimbang dan efek pembebanan turun menjadi 13,4%.

Three-phase induction motor is a motor that has been widely used in large factory in general, in addition to efficient in terms of price, maintenance is not too difficult. But did not close the possibility while in the field, the induction motor is damaged, one of which is the occurrence of
imbalance in the air gap. So it can cause the condition of air gap distance between rotor and stator not uniform or in unison where this condition is called eccentricity. To prevent sustained damage, this research is don
e in order to detect errors or damage early. This time the researcher tried to analyze the effect of load and
unbalance voltage by the spectrum of stator current in three phase induction motor with eccentricity air
gap and focused on static eccentricity condition. The results of this data will be processed using existing
methods is Fast Fourier Transform (FFT). For curret signature seen at steady state condition.
The results of the experiments show the effect of load to rate percentage detection rate 67%. As for the unbalanced voltage and load effect down to 13.4%
