How does the servo motor drive work
The power drive unit is the first through the three-phase full bridge rectifier circuit to the input three phase electricity or the municipal electricity to complete the rectifier, the corresponding direct current electricity. The three phase permanent magnet synchronous ac servo motor is driven by a three-phase sinusoidal PWM voltage inverter. The whole process of the power drive unit can be simply described as the ac-dc-ac process. The main topological circuit of the rectifier unit (ac-dc) is a three-phase fully bridge uncharged rectifier circuit.
Servo driver: (servo drives) is also known as "servo controller and the servo amplifier, a controller is used to control the servo motor, its action is similar to the frequency converter applied to ordinary ac motor, belonging to the part of the servo system, mainly used in high precision positioning system. Typically by location, speed and torque three ways to control the servo motor, high precision positioning of transmission system, is currently the transmission technology of high-end products. How it works: The current mainstream servo drives are controlled by digital signal processors (DSP). It can implement the more complicated control algorithm, realize digitization, network and intelligence. Power devices are widely used in intelligent power module (IPM) as the core design of drive circuit, IPM internal integrated drive circuit, at the same time has the overvoltage, overcurrent, overheating, under-voltage protection circuit, such as fault detection in the primary loop to join the soft start circuit, to reduce the impact to drive during startup.
