摘要
论述MG250/591-WD电牵引采煤机截割电机恒功率控制系统,确保截割电机始终工作在额定功率附近。根据截割电机负载状态来自动调节采煤机的牵引速度,使采煤机的截割电机工作在额定功率范围内,即所谓"恒功率"控制。
The exposition about MG250/591 -WD electric haulage shearer cutting motor constant- power control system guarantees the cutting motor to operate throughout nearby the rated power. Haulage speed of shearer was automatically adjusted by the cutting motor load condition, which made cutting motor of shearer working in the range of rated power, this is called constant - power control.
