Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FR-A840-00038-2-60 PLC FUNCTION Manual FR-A840-00038-2-60 Programming Manual FR-A840-00038-2-60 PLC FUNCTION Manual FR-A840-00038-2-60 Programming Manual. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
