Most customarily used motor in the industries are induction motor due to its low cost, robustness and less maintenance. The change in the existing framework is necessary in order to make the motor more efficient one. This paper cast enlightenment about the PLC based 3 phase multi-starter control induction motor with energy efficient single control system. In order to start the engine's operation by its own power, starters are used. Various starters are available to initiate the 3-phase induction motor namely Direct On-line, Star-delta, autotransformer and rotor impedance. The employment of this PLC based techniques helps to increase the energy efficiency of the motor .The employability of PLC in this system is to help in the growth of automation. The hardware and software results of the multi starter control using single control systems are analysed

В статье приводится описание разработки усовершенствованной системы регулирования аппарата укладки проволоки на стане тонкого волочения. Модернизация системы регулирования направлена на устранение недопустимого режима работы стана, когда намотка проволоки на катушку осуществляется без ее равномерной укладки, вследствие выхода из строя механизма реверсирования укладчика. Разработана функциональная схема системы защиты от остановки укладчика в процессе намотки проволоки на катушку. Реализация данной схемы выполнена на базе существующих систем регулирования преобразователей частоты в электроприводах аппаратов намотки и укладки. Приведено описание работы защиты от остановки укладчика. The article describes the development of an improved system for regulating the apparatus for laying wire on a thin drawing mill. The modernization of the control system is aimed at eliminating the unacceptable mode of operation of the mill, when the wire is wound on a coil without evenly stacking it, due to failure of the stacker reversal mechanism. A functional diagram of the stacker stop protection system was developed during the process of winding wire onto a spool. The implementation of this scheme is based on existing systems for regulating frequency converters in electric drives of winding and stacking machines. The description of the operation of the protection against stopping the stacker is given.
