Abstract
Taking the permanent magnet drive system of underground belt conveyor in coal mine as the object,the technical performance,economy and maintenance cost of the permanent magnet direct drive system are analyzed,and the composition and structure of the permanent magnet direct drive system and the working principle of the permanent magnet motor are introduced in detail.By comparing and analyzing each drive system of the belt conveyor,the application status of the drive system is summarized,and the faults encountered in the practical application of the permanent magnet direct drive system are analyzed,which provides reference for the transformation,development and application of belt conveyor in other similar occasions in the future.关键词
