Servo feeder manufacturers believe that the servo system is the actuator of industrial automation production, which can change the direction, torque, speed and position, and is widely used in machine tools, mechanical arms and various processing machinery. As one of the important control systems of modern industrial production equipment, servo system is an indispensable part of industrial automation.

  Servo feederManufacturers believe that the servo system is the actuator of industrial automation production, which can change the direction, torque, speed and position, and is widely used in machine tools, robotic arms and various processing machinery. As one of the important control systems of modern industrial production equipment, servo system is an indispensable part of industrial automation.

1. High control accuracy. Servo feeder manufacturers believe that the servo system achieves closed-loop control of position, speed and torque, unlike stepper motors.

2. High speed. The rated speed of permanent magnet motor in general servo system can reach 2000~3000 r/min.

3. Strong anti-overload ability. Servo motors can generally withstand three times the rated torque, so it is very suitable for load transient fluctuations and fast start occasions.

4. Strong operation stability. Servo feeder manufacturers believe that the servo motor is stable at low speed, does not produce similar stepper motor step-by-step operation phenomenon, suitable for high-speed response requirements of the occasion.

5. Fast response speed. The dynamic response time of motor acceleration and deceleration is very short, generally within tens of milliseconds.

6. Good comfort. Compared with the stepper motor, the heat and noise of the servo motor are significantly reduced.

Servo feeder manufacturers believe that the servo control system is generally sufficient position control accuracy (positioning accuracy), position tracking accuracy (position tracking error) and fast enough tracking speed as the main control objectives. When the system is running, it is required to track the change of the instruction at any time with a certain accuracy, so the running speed of the servo motor in the system is constantly changing. Therefore, the servo system in the tracking performance requirements are generally higher than ordinary speed control system, more stringent. Due to the limitations of DC motor brushes and commutators, as well as the high production and maintenance costs of DC servo systems. With the emergence of new control devices and motor control methods, servo systems have widely replaced DC servo systems.

The servo feeder manufacturers believe that according to the different signal processing methods, the servo system can be roughly divided into digital-analog hybrid servo, analog servo and all-digital servo. According to the type of servo motor used, it can be divided into three types: one is a servo system composed of permanent magnet synchronous motors, including square wave permanent magnet synchronous motor (brushless DC motor) servo system and sine wave permanent magnet synchronous motor servo system; The other is a servo system composed of squirrel cage asynchronous motors. The difference between the two is that the permanent magnet synchronous motor servo system needs a magnetic pole position sensor, while the induction motor servo system includes a slip frequency calculation part. If the microprocessor software is used to realize the servo control, the permanent magnet synchronous servo motor and the squirrel cage asynchronous servo motor can use the same servo amplifier.
