24 V直流电机正反转实训装置的开发与应用

Development and Application of 24 V DC Motor Forward and Reverse Experimental Device

实验课程是电工电子技术教学的重要组成部分。长期以来,因为安全等因素,“电动机的正反转控制电路”只能作为演示实验,造成理论与操作联系不够紧密,学生不能完整掌握该实验技能。因此,设计了新的24 V直流电机正反转实训电路实验来满足师生的教学需求,主要介绍了该实验的电路原理及实验目的,同时分析了该实验的优点及应用效果。

The laboratory course is an important part of the teaching of electrical and electronic technology, because of security and other reasons,“motor forward and reverse control circuit” can only be used as a demonstration experiment, resulting in the lack of close connection between theory and operation, and students can not fully master the experimental skills. Therefore, we designed a new experiment of 24 V DC motor forward and reverse experimental circuit to meet the teaching needs of teachers and students. This paper mainly introduces the circuit principle and purpose of the experiment, and analyzes the advantages and application effects of the experiment.
