摘要
近些年来，采用变频器对泵类机械进行转速控制来调节流量的方法，已经在工业上获得普遍的实际应用，这对节约能源提高经济效益具有重要意义。在电力拖动的领域里，从节约能源的观点出发也在重新评估各种拖动方式。节约能源特别有潜力的一个方面就是过去被认为没有必要进行速度控制的领域。在这些领域中，经过调查研究就会发现有不少浪费能源的实例。例如泵类机械的流量控制，过去很少采用转速控制方式，多是鼠笼式异步电动机拖动进行恒速运转，当需要调节流量时，实际采用的办法是调节截流阀，这种控制当然简便，但从节省能源的观点来看，就不如采用传感器构成闭环反馈来时刻调节鼠笼式异步电动机转速的自动化控制。

Title Auto-Control System of resin content design in Digital Control Winding Machine

Abstract
In recent years, the inverter is used for the mechanical pump speed control to regulate the flow. It has been in the universal practical application .It is of great significance to enhance economic efficiency of energy conservation.In the fields of electricity Driving, from the point of view energy conservation drag way is also re-assessed. The potential aspect of energy conservation is the field that in the past was not considered necessary to control the speed . In these areas, after the investigation there are a number of examples of energy waste. For example, the mechanical pump flow control, in the past it is few to use speed control mode. Most of squirrel-cage induction motor drive for constant speed operation, when the need to regulate the flow, the practical approach is to adjust valve closure,.This kind of control is very simple, but in the point of energy savings , it should use the closed-loop feedback sensor time to adjust squirrel-cage induction motor speed.
