Prinsip kerja encoder ini berdasarkan perubahan kapasitansi yang dihasilkan oleh rotasi dari pelat-pelat tertentu ke posisi yang berbeda. Encoder ini sangat penting dalam aplikasi industri, robotika, dan otomotif.<\/p>\n<h2>Komponen dasar Encoder Rotary Kapasitif<\/h2>\n<p><u1><\/p>\n<li><strong>Stator:<\/strong> Bagian tetap yang biasanya berisi pelat-pelat kapasitif stator.<\/li>\n<li><strong>Rotor:<\/strong> Bagian bergerak yang mengandung pelat-pelat kapasitif yang berinteraksi dengan pelat-pelat pada stator saat berputar.<\/li>\n<li><strong>Sirkuit Pengolahan Sinyal:<\/strong> Bagian ini mengukur perubahan kapasitansi dan mengonversinya menjadi sinyal digital yang dapat diolah lebih lanjut.<\/li>\n<p><\/u1><\/p>\n<h2>Prinsip Dasar Kapasitansi<\/h2>\n<p>Kapasitansi (C) adalah kemampuan suatu sistem untuk menyimpan muatan listrik. Kapasitansi antara dua pelat konduktif dapat dihitung dengan formula berikut:<\/p>\n<p>C = \\(\\frac{\\epsilon A}{d}\\)<\/p>\n<p><u1><\/p>\n<li><strong>\\(\\epsilon\\):<\/strong> Konstanta permitivitas material dielektrik di antara pelat-pelat.<\/li>\n<li><strong>A:<\/strong> Luas permukaan pelat-pelat.<\/li>\n<li><strong>d:<\/strong> Jarak antara pelat-pelat.<\/li>\n<p><\/u1><\/p>\n<p>Pada encoder rotary kapasitif, rotasi rotor mengubah jarak relatif (d) dan area overlap (A) antara pelat-pelat kapasitif, menyebabkan perubahan kapasitansi.<\/p>\n<h2>Cara Kerja Encoder Rotary Kapasitif<\/h2>\n<p><o1><\/p>\n<li><strong>Pengukuran Kapasitansi:<\/strong> Ketika rotor berputar, jarak dan area overlap antara pelat-pelat stator dan rotor berubah, menyebabkan variasi dalam kapasitansi.<\/li>\n<li><strong>Konversi Sinyal:<\/strong> Perubahan kapasitansi ini diukur oleh sirkuit pengolahan sinyal, yang seringkali menggunakan metode osilasi untuk mendapatkan pembacaan yang akurat.<\/li>\n<li><strong>Pengolahan Digital:<\/strong> Sinyal analog yang dihasilkan oleh perubahan kapasitansi dikonversi ke dalam sinyal digital oleh Analog-to-Digital Converter (ADC).
