针对常规异步电动机带带轮的浮选机驱动装置存在的问题,提出了永磁直驱系统的方案。介绍了永磁直驱电动机及其驱动器的设计,对永磁直驱系统在现场的运行状况进行了分析说明。现场的运行状况表明,永磁直驱系统具有节能减排、简化浮选机结构、减少维护费用和易于调速等优点。
Aiming at the existing problems of the flotation machine driving device of the conventional asynchronous motor pulley, a scheme of permanent magnet direct drive system is proposed. The design of permanent magnet direct drive motor and its driver is introduced. The operation condition of permanent magnet direct drive system in the field is analyzed and explained. The operation status of the site shows that the permanent magnet direct-drive system has the advantages of energy saving and emission reduction, simplifying the structure of the flotation machine, reducing maintenance costs and easing speed control.
