Innovative application of permanent magnet variable frequency direct drive in"110 construction method"mining
In response to the demand for large capacity,long distance,no central drive,and intelligent variable frequency control of the belt conveyor system under the"110 construction method"intelligent mining mode of the 1009 fully mecha-nized mining face in the No.1 coal mine of Huangling Mining Company,the traditional drive structure of asynchronous motor+CST system is no longer suitable for the current environment.Through the innovative application of the permanent magnet variable frequency synchronous motor direct drive system,the structural composition of the permanent magnet synchronous variable frequency direct drive system,the characteristics of permanent magnet electric drum,and the advantages of variable frequency intelligent drive system are discussed and analyzed.Combined with the practical application of the 1009 intelligent mechanized mining face in No.1 Coal Mine and the upgrading and transformation of the coal flow load monitoring and speed regulation system,the intelligent permanent magnet synchronous variable frequency direct drive system has shown many ad-vantages in driving performance,transportation efficiency,maintenance and repair,intelligent monitoring,energy conservation and consumption reduction,dynamic speed regulation,foreign object detection,intelligent fault diagnosis,etc,playing a sup-portive role in the efficient and stable,and energy-conserving and consumption-reducing operation of the transportation sys-tem for the"110 Construction Method"intelligent mechanized mining face.
