Permanent magnet direct-drive conveyor

The permanent magnet direct-drive conveyor has been proved by industrial tests that the parameters are reasonable, the structure is advanced, and it can fully meet the needs of underground transportation, and has been widely used in the major mines. The traditional belt conveyor system adopts asynchronous motor, hydraulic coupler and decelerator to transmit the power to the drum to drive the belt, and the obvious defects of this traditional transmission way include: The efficiency of driving system is low, and it starts unstably, and the heavy load start is difficult, directly affecting the overall efficiency of the driving system. Mine party maintains and replaces the decelerator, coupler and other parts frequently.

The driving system through technical transformation adopts the no-gear permanent magnet synchronous motor frequency conversion driving system, namely, the driving system consists of permanent magnet synchronous motor and frequency converter which are combined to realize the power transmission, and the driving system has the advantages of high efficiency, energy saving due to removal of the decelerator, hydraulic coupler; and low noise, “free” from maintenance; it also has the advantages of large output torque, smooth starting and constant torque control, etc.. Its successful research and development has made a useful exploration for our development of "green mining equipment" with independent intellectual property rights in the field of mining equipment.

Improving transmission efficiency, reducing power consumption, the energy consumption of Y series asynchronous motor used in the traditional drive system only reaches the international level IE1 (equivalent to the national level III energy consumption). The energy consumption of permanent magnet synchronous motor used in the system has reached the international IE4 (higher than the national level I energy consumption standards). Similarly, a set of DSJ80 belt conveyor can save power for RMB one hundred thousand per year.

The system realizes soft starting and free maintenance. The system controls the starting with frequency converter and realizes the slow and uniform starting of the system transmission. At the same time, compared with the original system, it eliminates hydraulic coupler, decelerator and synchronous gear, so the maintenance cost can be saved for at least RMB 30,000.00 to 50,000.00 per year, accordingly reducing maintenance costs.
Realize power balance—When the system uses multi-motor master-slave control drive, power balance can be achieved to avoid the damage to the motor caused by multi-motor power imbalance.

Large starting torque—The permanent magnet synchronous motor of the system can constantly output the starting torque 2.8 times higher than the rated load torque, while the starting torque of the traditional asynchronous motor is 55% of the rated load.
