目前矿用提升绞车大多采用绕线电机串电阻器调速,这种调速方法是有级的,而且启动力矩大、速度不平稳、电气元件多、占地面积大、噪声大、耗能多和成本高,而采用鼠笼电机变频调速,可节电50％,实现无级调速,无噪声,绞车的启动、停止、加速和正反转等控制功能均由变频器完成,控制 At present, most mine hoist windings motor winding resistor speed control, this speed control method is a class, and the starting torque, speed is not stable, the electrical components and more, covers a large area, noise, energy consumption and more And the cost is high, and the squirrel cage motor frequency control, energy saving 50%, to achieve stepless speed regulation, no noise, winch start, stop, acceleration and reversing and other control functions are completed by the inverter, control
