Application of 10 kV Permanent Magnet Direct Drive Integrated Machine in Intelligent Coal Mine Equipment
Abstract：To address the issues of traditional belt conveyor drive systems in the coal mining industry, which consist of mobile transformer substations, explosion-proof frequency converters, high-power asynchronous motors, and gearboxes, leading to complex systems, low transmission efficiency, and difficulties in intelligent development, key technologies such as multi-channel IGBT cross-distributed magnetic circuit voltage balancing topology design, high-voltage CVFC (complex frequency domain vector control) algorithm, high insulation and efficient heat dissipation structure, and intelligent sensors were researched and developed. A 10 kV permanent magnet direct drive integrated machine was developed, featuring higher integration, power density, and intelligence level, simplifying the belt conveyor drive system and improving transmission efficiency.
