Starting the three-phase asynchronous motor is important in the teaching and experiment Electrotechnology.

步电动机启动，是《电工学》教学和实验重点内容。

Realizes the networked measure or control and asynchronous emluator.

实现了网络化测控与步仿真。

This paper briefly describes the problematic metastability in the asynchronous designs and presents a regular solution——synchronizer.

本文主要就步设计中涉及到亚稳态问题,作简要介绍,并提出常用解决办法——即同步器使用。

Besides the property of the asynchronous motor,the taper asynchronous motor can daff the detent easily,because magnetic force is generated when stator three-phrase windings connect to the electricity.

锥形步电动机除具有一般步电动机性能外,还因定子绕组接通电源时产生轴向磁拉力,可顺利推开制动器,从而使锥形步电动机正常运行。
