1. Impedance voltage drop: Impedance voltage drop is the actual voltage drop across the reactor coil at XHz for the actual rated current. The impedance voltage drop is usually chosen to be around 1-4%.
2. Choice of inductance: The rated inductance of the reactor is also an important parameter! If the inductance is not properly selected, it will directly affect the voltage drop under the rated current, causing a malfunction. The amount of inductance depends on the cross-sectional area of ​​the reactor core and the number of turns of the coil and the adjustment of the air gap.
The selection of the inductance of the output reactor is mainly determined according to the length of the cable within the rated frequency range, and then the cross-sectional area of ​​the core and the cross-sectional area of ​​the conductor under the corresponding inductance are selected according to the actual rated current of the motor to determine the actual voltage. drop.
3. Inductance and cable length corresponding to rated current: cable length rated output current inductance.
4. Selection of rated AC current: The rated AC current is the long-term working current of the reactor designed from the aspect of heat, and sufficient high-order harmonic components should be considered. That is, the current actually flowing through the output reactor is the output current of the inverter motor load.
