Do You Know What Is The Servo Drive?

Servo driver is very common in our life and industry, so what is servo driver?

Servo driver is an electronic device. Its main parts are circuit board, microchip, wire and connector. Linking these electronic components together can control the rotation of the motor. They can accelerate, decelerate, stop or even reverse the motor at any time. Without a servo drive, the motor may rotate uncontrollably or not at all. Servo driver is very common in our daily life, such as electric vehicle, manipulator, automation equipment and so on.

What is servo drive?

Servo drives, also known as "servo controller" and "servo amplifier", are a kind of controller used to control servo motor. Their function is similar to that of frequency converter acting on ordinary AC servo motor. They belong to a part of servo motor system and are mainly used in high-precision positioning system. Generally, the servo motor is controlled by position, speed and torque to achieve high-precision transmission system positioning. It is a high-end product of transmission technology.

The reasons of why servo drives are important

Servo driver is an important part of modern motion control. It is widely used in industrial robots, CNC machining centers and other automation equipment. Especially, the servo driver used to control AC permanent magnet synchronous motor has become a research hotspot at home and abroad. At present, the current, speed and position closed-loop control algorithm based on vector control is widely used in the design of AC servo driver. Whether the speed closed-loop design is reasonable or not plays a key role in the whole servo control system, especially in the performance of speed control.

In the speed closed loop of servo driver, the real-time speed measurement accuracy of motor rotor is very important to improve the dynamic and static characteristics of speed control. In order to find the balance between measurement accuracy and system cost, the incremental photoelectric encoder is generally used as the speed sensor, and the corresponding common speed measurement method is m / t speed measurement method. Although M / T speed measurement method has certain measurement accuracy and wide measurement range, this method has its inherent defects, mainly including at least one complete code disk pulse must be detected in the speed measurement cycle, which limits the minimum measurable speed and the timer switches of the two control systems used for speed measurement are difficult to keep strictly synchronized, and the speed measurement accuracy cannot be guaranteed in the measurement occasions with large speed changes. Therefore, the traditional speed loop design scheme using this speed measurement method is difficult to improve the speed following and control performance of servo driver.

Generally speaking, through the introduction of servo driver, servo driver is an important part of modern motion control. It is widely used in automation equipment such as industrial robots and CNC machining centers. In particular, the servo driver used to control AC permanent magnet synchronous motor has become a research hotspot. If you want to know more about professional servo driver, you can consult Ouke.
