6SC6101-2B-Z微信里有同行问，直流调速器输出到底接几根线？可见在工业设备维修的普及有多远。直流调速器原理都是控制马达做功，顾名思义，直流调速器能控制的，当然就是直流马达了。大功率直流马达制造复杂，价格昂贵，数字直流调速器的特点是体积小，
输出功率大，技术难点是控制电路复杂且要求极高的响应速度。举个例子：660v交流变频器要做到1500kw以上的功率，硬件成本不说，光机箱大小就得好几个十个立方了吧，直流调速器输出同样功率的块头，两个立方米足够了。直流调速器在钢铁、橡塑、能源、化工等大功率，低速高扭应用的场合，一直有着和变频同样重要的地位。A colleague in WeChat asked how many lines are connected to the DC governor output? It can be seen how far the popularization of industrial equipment maintenance is. The principle of DC speed governor is to control the motor to do work. As the name implies, the DC speed governor can control, of course, the DC motor. The manufacturing of high-power DC motor is complex and expensive. The digital DC governor is characterized by small size and large output power. The technical difficulty is that the control circuit is complex and requires high response speed. For example, if 660v AC frequency converter is required to achieve power above 1500kw, the hardware cost is not to mention that the chassis size should be several ten cubic meters. Two cubic meters is enough for DC speed regulators to output blocks with the same power. DC speed regulators have always played the same important role as frequency converters in the applications of steel, rubber and plastic, energy, chemical and other high-power, low-speed and high torque applications.
