Abstract Based on the disadvantages of mine AC drive control hoist, Holzer Mine was taken as example, NT hoist electronic control equipment adaptive was studied, the auxiliary shaft realized 6RA70 rectification and 12 impulse DC drive control. Software real-time monitoring showed that five-paragraph speed curve, the armature current was continuous and stable. The system performance is stable and reliable, which could meet the needs of hoist control technology.
