Chapter 1 Introduction
Linear Servo Feed System
A linear servo feed system is a type of motion control technology used by many industrial automation applications. It is based on a servo motor attached to a linear actuator, which essentially translates the rotational motion of the servo into linear motion. Linear servo feed systems are used to move work pieces in precision applications, and typically includes a variety of options such as ballscrews, linear bearings, and servo drive controllers.
Linear servo drives generally offer higher speeds and accuracy compared to mechanical linear drives. This technology can be used for a wide range of applications such as material handling, machine tooling, and medical devices. Linear servo drives are also useful for applications requiring fast response time and repeatability.
Advantages of Linear Servo Drives
The main advantage of using linear servo drives is their adaptability to various applications. They can be used to move work pieces in precision applications as well as materials handling where accuracy and speed is required. This type of system is also popular for robotics applications.
Another advantage is their compatibility with a variety of control systems. Linear servo drives can be connected to programmable logic controllers (PLCs), industrial computers, and even universal robots for more advanced automation tasks.
These drives are also highly reliable and efficient. They are designed for industrial use, offering high performance and long service life.
Control Modes
The most common control mode used for linear servo drives is position control. In this mode, the servo motor is instructed to move from a position to another. The motor will move until it reaches the prescribed position and stops.
Velocity control is another type of control mode. In this mode, the servo motor is instructed to spin a certain speed, while at the same time maintaining a certain torque. This control mode is often used in applications such as packaging and cutting.
Finally, torque control is the third type of control mode. In this mode, the servo motor is instructed to apply a certain level of torque while spinning at a certain speed. This control mode is used in applications such as welding and drilling.
Chapter 2 Conclusions
Linear servo feed systems are a popular motion control technology used in many industrial applications. These systems offer high speeds, accuracy, and adaptability to various automation tasks. They are also compatible with a variety of control systems, including programmable logic controllers, industrial computers, and universal robots.
The most common control modes used with linear servo drive systems include position control, velocity control, and torque control. Each control mode is used in a different type of application and offers different levels of performance.
Linear servo feed systems are highly reliable and efficient, and offer a wide range of performance capabilities for a variety of industrial tasks. With the ever-increasing demand for more precise and advanced automation, linear servo drive systems will continue to be an important part of the automation industry.
