What is the use of Vector inverter?

The working principle of Vector inverter is to perform rectification first, and then inverter, and get the frequency and voltage you want after inverter.

The Vector inverter technology is based on the DQ axis theory. Its basic idea is to decompose the motor current into D axis current and Q axis current. The D axis current is the excitation current and the Q axis current is the torque current. The excitation current and torque current of the AC motor are controlled separately, so that the AC motor has similar control characteristics as the DC motor. It is an ideal control theory designed for the AC motor, which greatly improves the control characteristics of the AC motor.

Advantages of vector control:

1. Dynamic high-speed response;

2. Increased low-frequency torque;

3. Flexible control;

Application range of vector control system:

1. Work machinery that requires high-speed operation;

2. Adapt to the harsh working environment;

3. High-precision electric drive;

4. Four-quadrant operation;
