其次许多用于控制步进电机、感应电机和直线电机的驱动器仍然可以控制伺服。仅仅因为咖啡杯被用作铅笔架，它仍然是一个咖啡杯。我们今天的智能手机所做的远不止是打电话。伺服驱动器并不仅仅局限于它们最初的用途。
然而总会有例外(以及严格执行例外的坚持者)。有些电子器件是专门为另一种类型的电机设计的，如步进驱动器(或步进放大器、步进驱动器等)，因此在这种情况下，伺服驱动器在技术上是一个不恰当的名称，但对大多数来说仍然可以接受。其他人可能会争辩说，如果驱动器操作的是非伺服电机，就不恰当地称其为伺服驱动器。由于这个原因，像电机驱动器、电机放大器和电机驱动器这样的术语可以用作一个总括性术语。
先进的运动控制数字伺服驱动器从我们的PEVE和PEAR驱动系列家族可以轻松配置控制线性电机，交流感应电机，两三相步进电机，声音线圈或更多!我们称它们为伺服驱动器，我们坚持使用它。
这是一个棘手的问题。是的，伺服驱动器确实为电动机提供了控制元素。没有电动机驱动器，您将失去控制。但是，根据需要操作电动机，它们是控制器吗？有时是，但并非总是这样。
让我们再次回到过去的伺服放大器时代。电机确实是从放大器获得的功率运行的。放大器的确为无刷电动机提供了三相调相，这对于电动机的正确运行至关重要。然而，最重要的是，放大器做了一件事情：放大。他们从诸如拨盘，滑动开关或计算机之类的外部源接收命令信号，并以此为基础为电动机供电。如果要更改电动机的转矩，速度或位置，则必须更改命令信号。控制器就是传递该命令信号的东西。
现在，伺服驱动器已经变得更加先进，但是驱动器和控制器之间的界限可能会有些模糊。有些模拟驱动器中内置有电位计，因此，如果有人要通过手动调节增益或偏移电位器来控制电动机（就像我们在IMC上进行测试时有时做的那样），则该驱动器在技术上将充当控制器。也就是说，这些过程通常在调整过程中完成，而不用作实际应用程序的控制输入。

Secondly, many drivers used to control stepper motors, induction motors, and linear motors can still control the servo. Just because a coffee cup is used as a pencil holder, it is still a coffee cup. Our smartphones today do much more than make phone calls. Servo drives are not limited to their original purpose.
Yet there will always be exceptions (and those who stick to them). Some electronics are specifically designed for another type of motor, such as stepper drivers (or stepper amplifiers, stepper drivers, etc.), so in this case, servo drivers are technically an inappropriate name, but still acceptable for most. Others may argue that a drive is improperly called a servo drive if it operates a non-servo motor. For this reason, terms like motor driver, motor amplifier, and motor driver can be used as an umbrella term.
Advanced motion control digital servo drives from our PEVE and PEAR drive families can be easily configured to control linear motors, AC induction motors, two-three-phase stepper motors, sound coils or more! We call them servo drives, and we stick to them.
This is a tricky question. Yes, the servo drive does provide a control element for the motor. Without motor drive, you will lose control. But, operating the motor as needed, are they controllers? Sometimes, but not always.
Let’s go back to the era of servo amplifiers. The motor does run from the power obtained from the amplifier. The amplifier does provide three-phase phase modulation for the brushless motor, which is essential for the correct operation of the motor. Most importantly, however, amplifiers do one thing: amplify. They receive command signals from an external source such as a dial, slide switch, or computer, and power the motor based on this. If you want to change the torque, speed or position of the motor, you must change the command signal. The controller is what transmits the command signal.
Nowadays, servo drives have become more advanced, but the line between drive and controller can be somewhat blurred. Some analog drivers have a potentiometer built into them, so if someone were to control the motor by manually adjusting the gain or offsetting the potentiometer (as we sometimes do when testing on IMC), that driver would technically act as a controller. That is, these processes are usually done during the adjustment process and are not used as control inputs for real applications.
