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.
