Vector inverter technology is based on DQ axis theory and produced, its basic idea is to decompose the current of the motor into D axis current and Q axis current, where D axis current is excitation current, Q axis current is torque current, so that the AC motor excitation current and torque current can be controlled separately, so that the AC motor has similar control characteristics to the DC motor, is an ideal control theory designed for AC motor, greatly improving the control characteristics of AC motor.

Vector control technology through coordinate transformation, the three-phase system equivalent transformation into M-T two-phase system, the AC motor stator current vector decomposition into two DC components (that is, magnetic flux component and torque component), so as to achieve the purpose of controlling the magnetic flux and torque of AC motor respectively, so as to obtain the same good control effect as DC speed regulation system.
