摘要
异步电机是一种为数众多的动力设备,当电机运行于轻载或空载时,其效率和功率因素都很低.控制电机的功率因素就是节电,本文系统阐述了用8031单片机对电动机的功率因素进行检测和控制的设计思想,系统的硬件及软件设计方法.
<ABSTRACT> Asynchronous motor is a kind of popular power equipment. When the motor is in light or idle run, the efficiency is quite low. The key to improve this problem of evectricity saving. This paper gives a systematic inustration to the design, hard ware and software of 8031 type monochip motor and its function in motor efficiency testing and antrol.
