Rancang Bangun Sistem Pengereman Dinamis Motor Induksi Tiga Fasa Menggunakan Injeksi Arus Searah
ABSTRACT
The ultimate goal of this project is to create a dynamic braking system for a three-phase cage rotor induction motor. This can be done with four circuit models, one of which is dynamic braking using direct current injection. Direct current injection is obtained from an uncontrolled full-wave three-phase rectifier circuit originating from a single-phase transformer. This single-phase transformer is combined into a three-phase transformer with the primary side connected to a star. and the secondary side is connected to a star. To regulate direct current injection can be done by changing the resistance on the rheostat. The final results of the tests carried out can be concluded that the greater the direct current injected, the faster the induction motor stops rotating, and all the smaller the direct current injected, the longer the stop time of the induction motor will be.
