Abstract

Almost all industries use induction motors as production aids, this is due to several reasons, namely, the resulting rotational speed is constant, the induction motor does not have a brush so that the friction loss can be reduced, and easy maintenance. In this study is to detect damage to the stator winding caused by lamination of the windings so that a short circuit occurs in one phase, which is also called a turn fault. The Fast Fourier Transform (FFT) method is used to detect currents with a load of 0%, and 100% which will later be detected for classification on the Neural Network (NN). Categorizing the level of loading and the level of damage experienced by induction motors, namely turn to turn u1, turn to turn u1 and v1, and turn to turn u1, v1 and w1. The reading of the test results conducted on the Neural Network has good prediction results because the Mean Squared Error (MSE) produced does not exceed the specified 5% erracy level.

Abstract

In applications in the industrial world, the use of induction motors has been widely used in operation because induction motors have many advantages, although they have many advantages, induction motors themselves also have disadvantages, namely having high starting currents. In many cases the damage to the induction motor, the damage to the stator due to a short circuit, is a frequent failure, this damage can cause considerable losses because the motor can stop operation So this research will discuss about the detection of short circuit faults in the stator winding through leaky flux using a flux sensor that is placed outside the motor and placed radially and using the Fast Fourier Transform (FFT) method. Damage to the short circuit is done by reconstructing the stator winding of the induction motor. There are two variations of short circuit damage, namely short circuit winding 1 to winding 3 and short circuit winding 2 to winding 10 on an induction motor. The short circuit data is then processed using the Fast Fourier Transform method which produces data in the form of voltage to frequency. The results of the percentage of success of short circuit fault detection seen from the loaders have an average percentage of 50%, at no load conditions can detect short circuit faults by 100%. In conditions of short circuit interruption 1-3 has a success percentage of 30% and short circuit fault 2-10 by 70%. The existence of this system is expected to be able to anticipate any damage that can cause considerable and fatal losses.

Abstract

Motor Brushless DC merupakan jenis motor yang sangat sering digunakan pada masa ini, keandalan motor ini sangat terpercaya sehingga penggunaanya pun sangat banyak. Penggunaan motor BLDC konvensional memerlukan beberapa komponen sebagai kontrolnya yaitu transformator, rectifier dan inverter. Penggunaan komponen inverter disini diperlukan karena motor BLDC sendiri memerlukan gelombang persegi untuk bekerja, namun inverter menyebabkan tinginya nilai distorsi harmonik yang menyebabkan juga turunya faktor daya pada motor BLDC, hal ini dikarenakan swithcing dari inverter itu sendiri, di sisi lain perlu kita bahwa motor BLDC merupakan beban non-liner. Dalam penelitian ini akan digunakan suatu konverter untuk memperbaiki faktor daya serta mengatur naik turunnya tegangan, konverter itu tidak lain adalah buck boost konverter. Konverter ini bertugas sebagai penstabil tegangan dan menyaring ripple arus dan tegangan sehingga dihasilkan fakor daya yang sesuai standart PLN yaitu 0,8. Nantinya konverter akan dikontrol oleh rangkaian kontrol yang berbasis PID.
