RESEARCH ON THE OPERATION OF AN AUTOMATED ELECTRIC DRIVE FOR A WORKPIECE TRANSFER MECHANISM

Abstract

Current trends in the development of technological process automation systems are moving towards the creation of automatic systems capable of performing specified functions or procedures without direct human involvement. The role of the human operator is to prepare the necessary input data, select the operating algorithm (or solution method), and analyze the results obtained. Moreover, these trends can be observed not only in the automation of complex technological processes in industry, but also in other areas of human activity. Asynchronous electric motors with short-circuited rotors will be used to set the mechanisms in motion, which will be controlled by frequency converters. The implementation of this automation system will optimize the control of the installed mechanisms and reduce the role of the human operator in the control process.

The paper presents research the operation of an automated electric drive for a workpiece transfer mechanism. The problems of controlling the automated electric drive of the workpiece transfer mechanism are described, and the requirements for the electric drive of the workpiece transfer mechanism are characterized. The main equipment of the system and the main elements of the power circuit of the automated electric drive of the workpiece transfer mechanism have been selected. The static characteristics of the automated electric drive, the parameters of the asynchronous electric motor connection circuits, and the transient processes of the automated electric drive of the workpiece transfer mechanism are calculated, and the integral indicators of the transient processes are determined.
