摘要
本文介绍了基于电力拖动的一种电动机的启动停止的设计方案,将两台电动机成功的顺序启动,逆序停止。我们运用其原理的思路是:用两套异步电机M1和M2,在M2控制回路中串入常开触头,实现只有先开M1才能后开M2,在M1停机按钮上并联一常开触头,实现只有先停M2才能后停M1。系统用到的元件有常开常闭开关,熔断器,继电器等一些常用的电气元件。绘制电路图与工作流程图,并进行改进。因为三相电机的仿真具有很高的难度,在短时间内无法完成,故只使用原理图和电路图进行说明。

Abstract
This paper introduces the electric drive based on a motor start stop design scheme, the two electric motors successful sequence startup, inverted order to stop. We use the train of thought of its principle is: with two sets of asynchronous motor M1 and M2, in M2 control loop of the string into normally open contacts, realize only first open M1 after can open M2, in M1 stop button on the parallel a normally open contacts, realize only first stop M2 can stop after the M1. The system use components have normally open normally closed switch, fuse, relay and so on some commonly used electrical components. Draw circuit diagram and working flow chart, and makes some improvement. For the simulation of the three-phase motor has high difficulty, unable to complete in a short time, so only use principle diagram and the circuit diagram shows.
Keywords: asynchronous motor M1 and M2; Normally open normally closed switch; Fuse; relay
