Braking System Planning on 3 Phase Induction Motors Using Full-Wave Rectifiers

Abstract

Induction motors are the most commonly used motors in various industrial equipment and public facilities such as conveyors, pump rotation, elevators, escalators. Induction motors that have rotors have remaining rotation when the engine is turned off, to rotate the motor in the opposite direction often waiting until the rotor stops rotating. This study is the result of the design and study of the manufacture of a three-phase induction motor braking device, where the use of a wave rectifier safety device will stop the remaining rotating field by reversing the rotating field by injecting DC current into the rotating field so that the rotating field stops. The test results show that the braking system when the tool is turned on in the first test and the second test, the current is stable with the initial forward current condition of 1.50 A, and the current when braking is 2.59 A.
