三相异步电动机节能优化控制器的设计

The Design of AVR Singlechip Computer the Efficiency Under three Different Step Motor Permanent Torque Load Optimizes the Controller

三相异步电动机是一种广泛使用的动力机械,每年消耗的电能占我国总发电量的50%以上。电机拖动应用领域中浪费现象比较普遍。本节能优化控制器的特色是在降压节能过程中即考虑降压范围又进一步找到电压和电流的最佳工作点,该方案用于对51 kW恒负载转矩准厚模块节能器的改造。具体介绍了该方案的节能原理,硬件结构和软件设计。

Three different step motors are a kind of motive power machine used extensively, the electric energy consumed every year accounts for more than 50% of the total generation of our country. At present, let 's pull electrical machinery wasting phenomenon not getting more general at application, especially in keep out by application of high - power, and the application study in this respect is relatively taught little, energy - saving appliance this characteristic to is it step down range find voltage and best operating point of electric current further to consider prompdy in the course of stepping down energy - conservingly, so make better energy - conserving result. This energy - conserving scheme is used for turning 51KW into the transformation of the torque accurate thick module energy - saving appliance of permanent load. This scheme has certain value of doing in the test to other research and development unit producing three different step motor energy - saving appliances.
