Abstract Belt conveyor is a very critical and important conveying equipment in coal mine engineering practice. The application of permanent magnet motor to belt conveyor has a good effect. Compared with the traditional asynchronous motor drive scheme, it can improve the drive efficiency. The TBVF-250/40YC permanent magnet motor and BPJ-630/1140 inverter are applied to DSJ100/63/2×160 belt conveyor of Nanshan Coal Mine. The application scheme is introduced and the control system is designed, including main circuit module, temperature control module, phase sequence recognition module and high and low speed control module. The field practice shows that the application effect of permanent magnet motor in belt conveyor is good, the overall structure is simplified, the working efficiency is improved and the operation cost is reduced. It is calculated that the 10 a time can save 15.1 million yuan for Nanshan Coal Industry.
