无刷双馈电相在矿山风机类负载中的应用研究

Brushless Double-fed Motor and Its Application Research for Driving Mine Fan-type Load

风机类负载采用调速驱动可节约大量能量,但由于缺少简单、可靠、经济的电机高速装置,该技术基本没有推广。无刷双馈电机调速是风机类负载节能降耗的理想方案。本文介绍了无刷双馈电机的结构和调速原理,在分析了该种电机能量关系的基础上,讨论了该种电机用于驱动风机类负载的优势。

The speed control driving for fan-type load can save much energy, but it is not popularized for lack of simple, reliable and economical motor speed control device. The speed control of Brushless Double-Fed Motor (BDFM) is an ideal scheme for saving the energy of fan-type load.The paper introduces the structure of BDFM and the principle of its speed control. The superiority of BDFM driving for fan-type load is discussed base on the analysis on its power relationship.
