What is Motion Control

它肯定没有秘密，制造业务正在快速现代化和升级，以满足客户对质量和立即交付的需求。自动化手动过程有强烈的转变，并且运动控制与此过渡的一体化。

At its core, motion control can be defined as a sub-field of automation that deals with moving individual parts of a machine in a controlled manner. This is especially helpful in applications such as production lines, where power, efficiency, and accuracy of movement are of vital importance. Not only does a motion control system enable movement, but, more importantly, it ensures that a machine can stop.

What Are the Components of Motion Control?

The term “motion control” doesn’t describe a particular component or part. Rather, it describes a group of individual components that all work together to create controlled movement in a machine. Some of the major parts include:

• 控制器 - 控制器就是 - 一种电子设备，其用作控制电机和驱动器的运动控制系统的“大脑”。特定应用中使用的控制器数量，例如在生产线中，将根据需要控制的各个过程的数量而变化。对于复杂的系统，可能有许多控制器。这些控制器中的每一个都能够接收来自控制整个生产线的主计算机的指令并提供反馈。

• Motor Drive - The motor drive serves as a middle-man of sorts between the controller and motor. It interprets the signal from the controller and then supplies the correct level of power to the motor to achieve the desired motion result.

• Motor - Motors used in motion control systems can take many forms and have many different applications. Their main function, though, is to receive inputs from the motor drive and convert these inputs into motion. Some types of motors typically used in motion control systems include:

• Stepper - Stepper motors tend to operate in a similar fashion to regular electric motors. However, due to the specific arrangement of magnets inside of them, each shaft rotation is able to be broken down into individual “steps”. An average stepper motor might have 200 steps of 1.8 degrees each per shaft rotation. This allows for highly accurate positioning of production line components.

• Servo - A servo motor provides a very accurate and powerful way to control angular motion.

• Linear Actuator - Linear actuators convert the rotational motion of a motor into linear motion similar to a pneumatic cylinder.
