摘要
为了充分利用电动机能量和保证高产高效,电牵引采煤机截割电动机应经常在额定功率附近运转,因此对电动机功率需进行自动控制,减少电动机的过载或欠载。
For full use of motor energy and to keep high productivity and high efficiency, when the cutting motor power of coal miner is bigger, the motor should often work at the rated power, so it is necessary to automatically control motor power to reduce over-load or under-load of motor.
