servo drives (servo drives), also known as "servo controller", "servo amplifier", is a controller used to control the servo motor, its role is similar to the frequency converter acting on the ordinary AC motor, is a part of the servo system, mainly used in high-precision positioning system. Generally, the servo motor is controlled through three ways of position, speed and torque to achieve high-precision transmission system positioning, and it is currently a high-end product of transmission technology.
In the speed closed loop of servo drive, the real-time speed measurement accuracy of motor rotor is very important to improve the dynamic and static characteristics of speed control of speed ring. In order to find the balance between measurement accuracy and system cost, incremental photoelectric encoder is generally used as the speed measurement sensor, and its corresponding common speed measurement method is M/T speed measurement. Although M/T velocity measurement method has a certain measurement accuracy and a wide measurement range, but this method has its inherent defects, including: 1) the speed measurement cycle must detect at least one complete code pulse, limiting the minimum measurable speed;
2) The timer switches of the two control systems used for speed measurement are difficult to maintain strict synchronization, and the accuracy of speed measurement cannot be guaranteed in the measurement occasions with large speed changes. Therefore, it is difficult to improve the performance of servo drive speed following and control by using the traditional speed loop design method.
Servo driver principle: At present, the mainstream servo drivers all use digital signal processor (DSP) as the control core, which can realize more complex control algorithms, and realize digitalization, networking and intelligence. Power devices generally use intelligent power module (IPM) as the core design of the drive circuit, IPM internal integrated drive circuit, and has overvoltage, overcurrent, overheating, undervoltage and other fault detection protection circuit, in the main circuit also add a soft start circuit to reduce the impact of the start process on the driver.
The power drive unit first rectifies the input three-phase or mains through the three-phase full-bridge rectifier circuit to obtain the corresponding direct current. The three-phase permanent magnet synchronous AC servo motor is driven by the three-phase sinusoidal PWM voltage inverter after the rectified three-phase power or mains. The whole process of the power drive unit can be simply said to be the AC-DC-AC process. The main topological circuit of the rectifier unit (AC-DC) is the three-phase full-bridge uncontrolled rectifier circuit.
