Development of Microcomputers and Motor Control Software for Steel Pipe Cutting Units

ABSTRACT: This paper designs the system for automatic regulation of the flying cut-off device for the moving pipe. For the main drive, there are introduced the direct-current motor, reductor, gear and gear-lathe, which is rigidly connected with cut-off device. The speed is regulated by the three-phase thyristor regulator which supplies the DC motor. For the process automation, a microcomputer is designed. On the basis of the projected hardware microcomputer, a software support is offered. The task for the newly projected system is to ensure improved accuracy of the cutting and increase the automation level.

KEYWORDS: hardware, length, microcomputer, motor, pipe, regulation, software, speed
