What is the big role of the coil of the automatic coil winding machine?

I. Blocking effect The self-induced electric potential in the inductor coil always competes with the change of current in the coil. The inductor coil has a blocking effect on the AC current. The magnitude of the resistance is called xl and is measured in ohms. The relationship between inductance l and AC frequency f is xl = 2πfl, and inductors can be divided mainly into high-frequency chokes and low-frequency chokes.

Second, tuning and frequency selection inductor coils and capacitors in parallel can form an lc-tuned circuit. That is, the circuit’s inherent oscillation frequency f0 is equal to the frequency f of the non-AC signal, and the inductive and capacitive resistance of the loop are also equal, so that the electromagnetic energy oscillates back and forth between the inductor and the capacitor, and the resonance phenomenon of the LC loop. The inductive and capacitive reactances of the circuit are inverted during resonance. The total inductance Z of the loop is small and the current Z is large (meaning f = “f0” AC signal). The lc resonant circuit has a function to select the frequency and can select an AC signal of a certain frequency f.
