ABSTRAK

Motor induksi tiga fasa banyak digunakan oleh dunia industry karena memiliki beberapa keuntungan antara lain motor ini sederhana murah dan mudah dan pemeliharaannya. Pada penggunaan motor induksi sering dibutuhkan proses menghentikan putaran motor dengan cepat terutama aplikasi untuk konveyor. Untuk menghentikan putaran rotor torsi pengereman diperlukan yang dapat dihasilkan secara mekanik maupun elektrik. Pengereman untuk menghentikan putaran motor induksi dapat dirancang secara dinamik yaitu sistem pengereman yang dilakukan dengan membuat medan magnetik motor stasioner. Keadaan tersebut dilaksanakan dengan menginjeksikan arus DC pada kumparan stator motor induksi tiga fasa setelah hubungan kumparan stator dilepaskan dari sumber tegangan suplai AC. Metode pengereman dinamik memiliki keuntungan antara lain kemudahan pengaturan kecepatan pengereman terhadap motor induksi tiga fasa dan kerugian mekanis dapat dikurangi dengan mengaplikasikan pengereman dinamik pada motor induksi tiga fasa didapatkan hasil proses menghentikan putaran motor induksi lebih cepat dibandingkan tanpa pengereman dinamik.


ABSTRACT

Three-Phase induction motors are widely used by the industry because it has several advantages among others the motor is simple inexpensive and easy maintenance. On the use of induction motors often takes the process to stop the motor quickly especially for conveyor applications. To stop the rotor the braking torque is required which can be produced mechanically or electrically. Braking to stop the induction motor can be designed dynamically namely the braking system is done by creating a magnetic field a stationary bike. The situation is carried out by injecting a DC current in the coil of three phase induction motor stator when the stator coil connection is released from the AC supply voltage source. Dynamic braking method has advantages such as ease of setting the braking speed of three phase induction motors and mechanical losses can be reduced by applying dynamic braking three-phase induction motors on the results obtained to stop the process of induction motor rotation is faster than without dynamic braking.
