Abstract

Kerusakan pada motor BLDC sering terjadi pada bagian belitannya. Kerusakan pada belitan inilah yang menyebabkan terjadinya hubung singkat antar belitan pada motor BLDC. Kondisi hubung singkat ini dapat merusak motor BLDC jika dibiarkan ataupun tak terdeteksi. Sangat penting untuk mengidentifikasi kerusakan hubung singkat. Tes surja adalah metode yang efektif digunakan untuk mengetahui kondisi motor BLDC. Pengujian surja dilakukan dengan memberi tegangan surja kepada belitan motor BLDC. Untuk membangkitkan tegangan surja dibutuhkan rangkaian pembangkit tegangan tinggi DC. Tegangan yang dihasilkan rangkaian pembangkit tegangan tinggi DC ini disimpan ke kapasitor surja. Kemudian kapasitor surja mengalirkan muatan surja ke belitan motor BLDC. Hasil pengujian surja dihitung menggunakan metode Error Area Ratio. Metode ini membandingkan nilai gelombang pada kondisi normal dengan nilai gelombang pada kondisi gangguan. Sehingga dapat menentukan kondisi motor dikatakan normal atau dalam keadaan rusak. Nilai EAR akan ditampilkan pada layar LCD. Pada pengujian normal motor BLDC, nilai threshold test-reff EAR yang didapatkan dibawah 10% sehingga masih dalam kriteria pass/fail Baker. Pada kondisi motor BLDC short antar belitan fasa A-B, A-C, dan B-C nilai threshold test-reff EAR memiliki nilai maksimal 95,94%, 96,64%, dan 96,65%. Nilai threshold test-reff EAR melebihi kriteria pass/fail yang terindikasi terjadi gangguan akibat short. ========================================================================================= Damage to the BLDC motor often occurs at the turns. This winding damage that causes a short circuit between windings on the BLDC motor. This short circuit condition can damage the BLDC motor if unchecked or not detected. It is important to identify short circuit damage. The surge test is an effective method used to determine the condition of a BLDC motor. The surge test is carried out by giving surge voltage to the BLDC motor windings. To generate a surge voltage a DC high voltage generator is needed. The voltage generated by this DC high voltage generator circuit is stored to the surge capacitor. Then the surge capacitor flows the surge charge to the BLDC motor windings. The surge testresults are calculated using the Error Area Ratio method. This method compares the wave value under normal conditions with the wave value under disturbance conditions. So that we can determine the condition of the motor is be normal or in a damaged state. The EAR value will be displayed on the LCD screen. This detection is in real time so that you will get a percentage of the EAR value directly. In the normal testing of the BLDC motor, the value of the EAR test-Reff threshold obtained below 10% so that still in Baker's pass/fail criteria. In the condition of the short BLDC motor between phases A-B, A-C, and B-C the threshold test-Reff of EAR has a maximum value of 95.94%, 96.64%, and 96.65%. The value of the EAR test-Reff threshold exceeds the pass/file criteria that occur due to short interference.
