变频器在工控维修行业中，是绕不开的入门级设备，变频器的主要作用就是驱动电机，把小信号转换为受控的交变电流电压。在实际维修中，驱动控制设备也是最容易损坏的

驱动的种类很多，其中变频器最具代表性的。乍一看，交流控制产品已经成为市场主流。但直流控制产品，事实上也并没有退出历史舞台，以abb公司的dcs直流调速器系列，西门子的6ra直流调速器系列为例，直流调速器的更新换代，几乎和变频器是同步的。直流调速适用于大功率，低速高扭的应用场合，虽然马达昂贵，维护也麻烦些，但其功率可观啊！轻而易举就可以做到兆瓦级别，而且控制精确度依然非常的理想。高端直流调速器技术，欧美最具代表性，这点连日本都不行。国内有生产，不是仿制品就是山寨货，没有叫得响的独立品牌，最具代表的如etd（易泰帝），其实血统还是泊来的，但已经好歹将复杂的操控界面中文化了，这点还是要点赞的。

交流近年进步最快的就是永磁同步驱动，但这玩意儿，对付一些大功率设备就要局限了，成本同样不低。然后就是伺服驱动，在所有的驱动器类别中，伺服的技术含量最高，具备三环反馈，对配套马达有严格的定义和要求。欧美的驱动，伺服，运动控制器，硬件设计上大抵是通用的，应用灵活，性能稳定。不同的控制场景，生产商都有自己核心的解决方案：刷伺服固件就是伺服控制器；刷变频器程序就是一台高性能的变频器。

Inverter in the industrial control maintenance industry, is the entry level equipment, the main role of the inverter is to drive the motor, the small signal into the controlled alternating current and voltage. In actual maintenance, the drive control equipment is also the most vulnerable to damage

There are many kinds of drives, of which the inverter is the most representative. At first glance, AC control products have become mainstream. However, DC control products, in fact, did not exit the historical stage, to abb's dcs DC governor series, Siemens 6ra DC governor series as an example, the replacement of DC governor, almost synchronous with the frequency converter. Dc speed regulation is suitable for high power, low speed and high torque applications, although the motor is expensive, maintenance is also troublesome, but its power is considerable! It is easy to achieve megawatts, and the control accuracy is still very ideal. High-end DC governor technology, the most representative in Europe and the United States, this is not even Japan. Domestic production, not imitation is copycat goods, there is no independent brand that is called, the most representative such as etd (Yi Tai Di), in fact, the blood is still poiso, but has somehow the complex control interface in the culture, this is still the point of praise.

The fastest progress in communication in recent years is the permanent magnet synchronous drive, but this thing, to deal with some high-power equipment will be limited, the cost is also not low. Then is the servo drive, in all the drive categories, the servo has the highest technical content, with three-ring feedback, and has strict definitions and requirements for the supporting motor. Europe and the United States drive, servo, motion controller, hardware design is generally universal, flexible application, stable performance. Different control scenarios, manufacturers have their own core solutions: brush servo firmware is the servo controller; Brush frequency converter program is a high performance frequency converter.
