变频调速一体机在刮板输送机中的应用

Application of Frequency Control of Motor Speed All-in-one in Scraper Conveyor

国内现有大多数煤矿井下刮板输送机驱动电机一般使用直接启动的方式,较少使用变频器或软启动驱动。现将变频调速一体机应用到煤矿井下刮板输送机中,占用空间小,电缆使用减少,易于安装;同时实现了软启动,电机启动电流远远小于额定电流,启动时间延长,减轻了起动机械转矩对设备的机械损伤,提高使用寿命,减少设备故障率,提高了煤矿生产效率。

Most existing domestic coal mine underground scraper conveyor drive motor generally use direct start, use fewer inverter or soft start driving. Will now be applied to the frequency control of motor speed all-in-one in coal mine underground scraper conveyor, small footprint, use reduce cable,easy to install; Realize the soft start at the same time, the motor starting current is far less than the rated current, start time, reduced the mechanical torque starting, the mechanical damage of equipment,improve the service life, reduce equipment failure rate, improve the efficiency of the coal mine production.
