Abstract

Magnetic bearing memang mempunyai banyak keunggulan dibandingkan bearing konvensional, yaitu kemampuan dalam mengurangi gaya hambat terhadap gesekan. Dalam perkembangannya, magnetic bearing dibagi menjadi dua jenis yaitu passive magnetic bearing dan active magnetic bearing. Pada tipe passive magnetic bearing beban yang dapat ditumpu tidak dapat bervariasi, bergantung pada kemampuan material magnet yang dipilih. Untuk menghasilkan gaya yang besar maka harus memperbesar dimensi dari magnet tersebut atau memilih magnet yang berbeda. Sehingga penelitian non-permanent magnetic bearing menjadi alternatif guna meneliti parameter-parameter yang mempengaruhi besar gaya radialnya. Active magnetic bearing memanfaatkan induksi magnetik yang timbul akibat adanya arus listrik yang mengalir pada kumparan sehingga mempunyai fungsi yang sama dengan passive magnetic bearing. Penelitian ini bertujuan untuk mengetahui beban maksimal yang mampu diterima pada AMB dan mengetahui pengaruh dari setiap variasi penelitian terhadap kemampuan angkat beban active magnetic bearing. Desain dan simulasi desain dilakukan dengan menggunakan software Ansys Electronic Maxwell 3D 19R1. Simulasi dilakukan dengan tiga variasi, yaitu variasi besar arus, jumlah kutub, dan jumlah kumparan. Variasi penelitian dilakukan guna meneliti pengaruh ketiga variasi tersebut terhadap beban maksimal yang mampu diterima oleh active magnetic bearing. Variasi eccentricity dilakukan dengan besar eccentricity 1.2, 1.3 dan 1.4, menyeseuaikan batasan ukuran bearing yang digunakan. Variasi besar arus dilakukandengan rentang arus 2-3 A, menyesuaikan batasan lilitan yang digunakan. Variasi kumparan dilakukan dengan rentang 110, 130 dan 150 lilitan. Eksperimen dilakukan dengan beberapa tahapan yakni instalasi peralatan dan objek sesuai dengan eksperimen, pengambilan data berupa besar gaya radial pada tiap variasi, dan pengujian dengan empat variasi pengaktifan pole untuk mendapatkan gaya radial maksimal masing-masing variasi tersebut. Dari analisis yang dilakukan didapatkan hasil perbandingan error untuk simulasi dan eksperimen untuk masing-masing variasi sebesar 1,62%-13% ; 3,8%-8,17% ; 1,57%-18% ; 1,03%-15,2%

Magnetic bearing is divided into two types, passive magnetic bearing and active magnetic bearing. In passive magnetic bearing the load that can be supported cannot be varied, but depends on the selected magnetic material. To produce a large force, it must enlarge the dimensions of the permanent magnet, but we know that bearing is a small component in the engine element. Therefore another type of magnetic bearing research is carried out, that is active magnetic bearing to examine the parameters that affect the radial force of the active magnetic bearing. Active magnetic bearing utilize magnetic induction that arising from a flowing electric current in the coil, so that they can replace the function of permanent magnet in passive magnetic bearing. This research is expected to improve the performance of magnetic bearing. Research on active magnetic bearing was carried out to analys the maximum load that can be accepted on active magnetic bearing and the effect of each variations on the carrying load capacity on active magnetic bearing. Then do the comparasion between carrying load capacity on active magnetic bearing and mechanical bearing of the same size so Design making and design simulation is done using Ansys Electronic Maxwell 3D 19R1. Simulation are carried out to examine the effect of variations made on active magnetic bearing, namely coil current, number of coil, and number of pole, and coil current. Variations in this study were carried out to analysis the effect of these three variations on the maximum load of active magnetic bearing. Variation of number poles is done by magnetic bearing configuration of 6 poles, 8 poles, and 10 poles, adjusting the size limitation od the bearing used The variation of the coil current is carried out in the 1 Ampere to 3 Ampere current range, adjusting the winding type that used. Variation of windings of coil per pole is 155,175 and 195. The experiment was carried out in several stages, namely the installation of equipment and objects in accordance with the experiment, data collection in the form of the radial force for each variation, and testing with four variations of pole activation to obtain the maximum radial force for each of these variations. From the analysis carried out, the results of the comparison of errors for simulation and experiment for each variation are 1,62%-13% ; 3,8%-8,17% ; 1,57%-18% ; 1,03%-15,2%.
