Renda current vector inverter is a vector control technology through coordinate transformation, the three-phase system equivalent conversion 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.
Application fields of Randa current vector inverter:
◆Control mode: no PG vector control, V/F control, torque control
