Abstract：Through the integration of planetary gear transmission mechanism,permanent magnet synchronous motor and drum,a new type of belt conveyor drive method-modular combination permanent magnet drive drum for mining has been successfully developed.It has the advantages of low speed,high torque,high efficiency and reliability,and flexible switching between single and double drives.It solves the problems of complex system,large maintenance,low efficiency,and high energy consumption in traditional drive methods,avoids the drawbacks of the direct drive method of permanent magnet motor,which significantly increases in volume and price with the increase of power and torque,breaks through the limitations of high-power(＞315 kW)external rotor permanent magnet drive drum in underground coal mines,and improves the overall performance of belt conveyors.At present,the 400 kW modular combined permanent magnet drive drum for mining has been applied underground in coal mines with good operating results.
