　　直流无刷电机针对纺织行业的应用和分析。

　　直流无刷电动机既具有交流电动机的结构简单、运行可靠等一系列优点，又具备直流电动机的运行效率高、调速性能好等诸多特点。结合直流无刷电动机在纺织机械中的广泛应用，说明了卣流无刷电动机在纺织机械设备的应用前景非常广阔。

　　直流无刷电动机是一种机械与电子相结合的一体化产品，它利用先进的电子换相取代了传统直流电动机的机械换相，从而从根本上解决了直流电动机的因为电刷的存在而带来的噪声、火花、无线电干扰、寿命短及需经常维护等致命弱点。直流无刷电动机仍保持了传统直流电动机良好的动、静态调速特性，且结构简单、运行可靠、易于控制。海恩弗无刷技术其应用已从最初的工业，迅速向航空航天、医疗、纺织机械、信息、家电以及工业自动化等领域发展。

　　随着纺织机械技术的发展和需要，现在的纺织机械上如络筒机、梳棉机及无纺布等需要大量的调速及控制电机作为原动力。目前纺织机械上需要调速的场合，多采用直流电动机或者异步电动机加变频器来实现，在精度要求较高的场合，多采用伺服电机进行控制。众所周知，传统的直流电动机均采用电刷以机械方法进行换向，因而存在相对的机械摩擦，由此带来了火花、寿命短以及需经常维护等致命弱点，从而大大地限制了它的应用范围。由于异步电动机的结构简单、价格低廉，目前在工业中大多数都采用异步电动机作为原动力。但为了对其速度进行控制，必须配以合适的变频器，从而大大提高了整个调速系统的成本，而且异步电动机本身的特点决定了其控制精度不高，更值得一提的是异步电动机在较低频(小于5 Hz)运行时，异步电动机多抖动的厉害，以致无法使用。

　　由于直流无刷电动机既具有交流电动机的结构简单、运行可靠、维护方便等一系列优点，又具备直流电动机的运行效率高、调速性能好等诸多特点，而且转子采用永磁结构，没有励磁损耗，提高了电动机的效率。因此该类电动机在纺织机械设备的应用前景非常广阔。

　　Application and analysis of Brushless DC motor in textile industry.

　　Brushless DC motor not only has a series of advantages such as simple structure and reliable operation of AC motor, but also has many characteristics such as high operation efficiency and good speed regulation performance of DC motor. Combined with the wide application of DC brushless motor in textile machinery, it shows that the application prospect of Youliu brushless motor in textile machinery equipment is very broad.

　　Brushless DC motor is an integrated product combining machinery and electronics. It uses advanced electronic commutation to replace the mechanical commutation of traditional DC motor, so as to fundamentally solve the fatal weaknesses of DC motor, such as noise, spark, wireless interference, short service life and frequent maintenance caused by the existence of brush. Brushless DC motor still maintains the good dynamic and static speed regulation characteristics of traditional DC motor, and has the advantages of simple structure, reliable operation and easy control. The application of haienfu brushless technology has rapidly developed from the initial military industry to the fields of aerospace, medical treatment, textile machinery, information, home appliances and industrial automation.

　　With the development and needs of textile machinery technology, a large number of speed regulation and control motors are needed as the driving force in current textile machinery, such as winder, carding machine and non-woven fabric. At present, the occasions that need speed regulation in textile machinery are mostly realized by DC motor or asynchronous motor plus frequency converter. In the occasions with high precision requirements, servo motor is mostly used for control. As we all know, traditional DC motors use brushes to change direction mechanically, so there is relative mechanical friction, which brings fatal weaknesses such as sparks, short service life and frequent maintenance, which greatly limits its application range. Due to the simple structure and low price of asynchronous motor, asynchronous motor is used as the driving force in most industries at present. However, in order to control its speed, it must be equipped with a suitable frequency converter, which greatly improves the cost of the whole speed regulation system. Moreover, the characteristics of asynchronous motor itself determine that its control accuracy is not high. What is more worth mentioning is that when the asynchronous motor operates at a lower frequency (less than 5 Hz), the asynchronous motor jitters so much that it cannot be used.

　　Because the brushless DC motor not only has a series of advantages such as simple structure, reliable operation and convenient maintenance of AC motor, but also has many characteristics such as high operation efficiency and good speed regulation performance of DC motor, and the rotor adopts permanent magnet structure without excitation loss, which improves the efficiency of the motor. Therefore, the application prospect of this kind of motor in textile machinery and equipment is very broad.
