Design of Electromotor Torsion Measuring System Based on Single- chip Microcomputer

本文介绍了一种电机转矩在线测量系统的结构原理和设计要点。该系统采用普通交流电机作为负载,对待测调速电机进行转矩测量。采用单片机对负载电机电流及待测电机转速进行数据采集,通过查表、计算,得出转矩值显示输出。本系统价格便宜,操作简单,测量周期短,精度可达到5%,可在生产流水线上对产品快速测量,替代昂贵的专业转矩仪,具有良好的性能价格比。

The structure and processing fundamental of a new kind of on-line electrumotor torsion measuring system is introduced in this paper.This system measures torsion of speed-shiftable motor on-line with an ordinary alternating current motor as load.It contains a microprocessor as center.It collects the current of its load motor and rotate speed of measured motor,then obtains and shows the torsion amount of the measured motor through querying the table and computing.This system is low-price and convenient to operator,and satisfied with industrial demands of 5% precision,so it can supersede expensive specialized torsion measuring equipment and get better benefits.
