In view of the current situation in China that taking energy efficiency improvement as the core, enterprises as the subject of implementation, vigorously adjusting and optimizing the structure, accelerating the energy-saving technology progress, to form a stable and reliable and energy saving ability as soon as possible so as to lay the solid foundation for the realization of the national energy saving target, this paper introduces the energy saving application of variable frequency speed regulating device of the main ventilator and main drainage pump in Huating Coal Group. It shows that the implementation of variable frequency speed regulation technology in the main ventilator and main drainage pump not only brings remarkable energy saving effect, but also can optimize the control performance of the entire power transmission system. On the premise of ensuring system security and stability, combined with the actual running situation, it can improve the motor system energy saving effect. It is expected to establish a good design for motor system energy saving application model to discuss the energy-saving application and development in China's motor system.%鉴于目前国内以提高能源利用效率为核心，以企业为实施主体，大力调整和优化结构，加快推进节能技术进步，尽快形成稳定可靠的节能能力，为实现国家节能目标奠定坚实的基础。本文介绍了变频调速装置在华亭煤业集团所属各矿井的主通风机、主排水泵的节能应用，说明在煤矿主通风机、主排水泵上实施变频调速技术不仅节能效果显著，而且可以优化整个电力传动系统的控制性能。在确保系统安全稳定的前提下，结合实际运行情况，提高电机系统节能效果。希望能为电机系统设计建立一个良好的节能应用模式，对我国的电机系统的节能应用和发展做一个探讨。
