Inductance coil blocking effect
Self-induced electromotive force in the coil of the inductor always counteracts the change of current in the coil. Inductance coil on the AC current has hindered the role of the size of the sense of resistance xl, the unit is ohm. It and the inductor l and the relationship between the frequency
f of xl = 2πfl, the inductor can be divided into high-frequency
blocking coil and low-frequency blocking coil.
Tuning and frequency selection
Inductor coil in parallel with the capacitor can be composed of lc tuning circuit. That
is, the natural frequency f0 of the circuit is equal to the frequency f
of the non-alternating signal, the inductance and the capacitance of
the loop are equal, so the electromagnetic energy oscillates back and
forth between the inductance and the capacitance, and the resonance
phenomenon of the lc loop. Resonance
and capacitive reactance of the circuit in resonance are reversed, the
inductance of the total current of the loop is smaller, the amount of
current is larger (AC signal of f = "f0"), the classification of the
inductive coil of the lc resonant circuit, the inductance The role of the role of the frequency of the coil can choose a frequency f AC signal selection.
Inductance coil can be classified according to different properties:
According to the inductor coil used by the coil heart material
points, there are core inductor coil, copper core inductor coil, ferrite
core inductor coil, hollow inductor coil, etc .;
According to the winding method of induction coil, there are
single-layer coils, multi-layer coils, close-wound coils, interwinding
coils, undrafted coils, honeycomb coils,
According to the use of inductive coil in the circuit to points,
there are oscillation coil, choke coil (choke coil), the filter coil
and so on.
According to the form of inductors: fixed inductors, variable inductors inductance coil classification, the role of inductors. The company is located in:
According to the nature of guided magnet Category: air-core coil, ferrite coil, core coil, copper coil. The company is located in:
According to the nature of the work: antenna coil, oscillation coil, choke coil, trap coil, deflection coil. The company is located in:
According to the winding structure categories: single-layer coil, multilayer coil, honeycomb coil.
