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。 Fan-type load speed control drive can save a lot of energy, but due to the lack of simple, reliable and economical high-speed motor devices, the technology has basically no promotion. Brushless doubly-fed motor speed control is the fan-type load saving the ideal solution. In this paper, the structure and speed regulation principle of brushless doubly-fed machine are introduced. Based on the analysis of the energy relationship of the motor, the advantages of this kind of motor for driving fan-like load are discussed.
