KNOWLEDGE BASE --- VFD Vector Control Method
Vector control, also known as field-oriented control (FOC), is a kind of control method of variable-frequency drive (VFD) in which the stator currents of a three-phase AC motor or brushless DC electric motor are identified as two orthogonal components which can be visualized with a vector.
The method of vector control of variable frequency speed regulation is to convert the stator currents Ia, Ib, Ic of an asynchronous motor in the three-phase coordinate system into the AC current Ia1Ib1 in the two-phase static coordinate system through the three-phase to two-phase transformation, and then change according to the directional rotation transformation of the rotor magnetic field, which is equivalent to the DC current Im1 and It1 in the synchronous rotating coordinate system (Im1 is equivalent to the excitation current of the DC motor, It1 is equivalent to the armature current proportional to the torque) and then imitates the DC current of the DC motor. Such a control method is to obtain the control quantity of the DC motor and realize the control of the asynchronous motor through the corresponding coordinate inverse transformation.
- The first section of VFD (variable voltage control) not only converts the AC supply voltage into DC but also controls the required pulsating DC output voltage to maintain V/f constant ratio by using SCR/IGBT rectifier.
- The second section of VFD (DC-Link/DC Bus) consists of inductance and capacitors to convert pulsating DC into pure direct current. Here, inductance smooths the current, and the capacitor smooths the voltage.
- The third section of VFD (referred to as variable frequency control) not only converts DC voltage back into AC voltage but also controls the variable frequency to maintain the V/f ratio by using electronic devices such as SCR/IGBT transistors.
- Cooling method-forced air.
- Keep away the ac converter from corrosive gasses, liquid, moisture, and dust.
- Installation location altitude below 1000m (In the case above 1000m, VFD is to be de-rated. Please contact for technical support).
- Storage-temperate -20℃ to +60℃.
- Ambient temperature -10℃ to +40℃ (non-condensing and not frozen).
- Ambient humidity below 90% RH.
- Vibration under 20Hz 9.8m/s(1G), over 20Hz 5.88m/s (0.6G).
- V/f (volts per hertz) or V/hz control.
- V/f with encoder or closed loop V/f (PG card).
- Open loop vector control.
- Closed loop vector control (PG card).
- VFD capacity is to be sized more or equal to the sum of the capacity of all connected motors.
- The sum of the distance between the VFD and all connected motors should be less than 500m. Introduce an output load reactor to avoid motor failure due to voltage spikes, current surges, or harmonics.
- Install circuit breaker MCB or with extra protection MPCB between each motor and VFD.
- The voltage of each motor should be the same and ensure the VFD adoptable current is higher than the sum of all rated currents.
- Connect all motors with VFD output in parallel.
