Research of electromechanical processes in the control system of a soft start device with an asynchronous motor

Abstract

The control system of the soft start device of an asynchronous motor with a constant load moment is considered. The study of electromechanical processes in the soft start device when working with an asynchronous motor was carried out due to simulated computer modeling in the Matlab software. The results of simulation modeling are given: oscillograms of input currents of the soft start device, dynamics of speed change and starting torque of an asynchronous motor. In the course of the simulation, it was established that the operation of the soft start device allows to reduce the starting current and starting torque.
