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 motor. They are part of servo 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. At present, it is a high-end product of transmission technology.

Folding processor

At present, the mainstream servo drivers use digital signal processor (DSP) as the control core, which can realize more complex control algorithms and realize digitization, networking and intelligence. Power devices generally adopt the driving circuit designed with intelligent power module (IPM) as the core. IPM integrates the driving circuit, and has fault detection and protection circuits such as overvoltage, overcurrent, overheating and undervoltage. Soft start circuit is also added in the main circuit to reduce the impact of starting process on the driver. Firstly, the power driving unit rectifies the input three-phase power or commercial power through the three-phase full bridge rectifier circuit to obtain the corresponding DC power. After the rectified three-phase power or mains power, the three-phase permanent magnet synchronous AC servo motor is driven by the frequency conversion of three-phase sinusoidal PWM voltage source inverter. The whole process of power drive unit can be simply described as AC-DC-AC process. The main topology circuit of rectifier unit (AC-DC) is three-phase full bridge uncontrolled rectifier circuit.
