The vector control ac motor drive is the converter?
Vector control of ac motor drive is one kind of frequency converter, also called vector frequency converter, speed hundred torque can be zero, such as the elevator in the air with the frequency converter control; Transformer is the input voltage according to certain proportion changed to output, after the switch power supply is to put the ac rectifier inverter dc power supply, transformer, switch power supply is punctuated with alternating current into direct current, can only use rectifier power supply or switch power supply, transformer
Simply put, vector control is to decouple the magnetic chain from the torque, and the regulator of the two can be designed to achieve the high performance speed adjustment of ac motor. Vector control method is based on slip frequency control of speed sensorless vector control method of vector control mode, and has a speed sensor vector control mode, etc. In this way, a three-phase asynchronous motor can be controlled by a dc motor, which is the same as the static and dynamic performance of dc speed control system. So that's the encyclopedia. That's pretty good. The concept of vector control was first discovered by Siemens engineers in a graduate thesis, which is widely used in domestic inverters. The traditional V/F control is more advanced and the advantages are obvious. The current frequency converter also has a control called direct torque control (DTC), which is only done by Siemens and ABB, and the DTC controls are more advanced. Which one doesn't understand
I can send you the data, there are two kinds of actuators, one is the servo actuator, one is the frequency converter, there is the mailbox, I send you an EMAIL.
The basic principle of vector control is through the measurement and control of asynchronous motor stator current vector, according to the principle of magnetic field orientation respectively excitation current and torque current of asynchronous motor to control, so as to achieve the goal of control of asynchronous motor torque. Concrete is causes asynchronous motor stator current vector is decomposed into the current component of the magnetic field (excitation current and torque current component of current (torque) control respectively, and at the same time control the amplitude and phase between the two components, namely the stator current vector control, so that the control method called vector control mode.
