Structure and manufacturing method of inductance coil Abstract: a structure and manufacturing method of inductance coil. The method is to wind the induction coil on the surface of rod-shaped magnetic core in order. The induction coil forms a reverse position at an appropriate position, and an appropriate resistance is connected in parallel with one end of the induc...

Metal plate inductive coil used in harsh environment The utility model relates to a metal steel plate inductive coil used in a harsh environment, which is provided with a conductive coil, which is characterized in that:(1) It is a thin steel wire coil surrounded by a plane formed after the space separation of the steel plate engraving, and is provided with four lay...

Inductance coil is a device that works by using the principle of electromagnetic induction. When a current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire itself of the electromagnetic field will induce the wire within the range of the electromagnetic field. The effect on the wire itself that generates the elect...

The performance index of inductance coil is mainly the inductance. In addition, the wire winding the inductance coil generally has a certain resistance, which is usually very small and can be ignored. However, when the current flowing through some circuits is large, the small resistance of the coil can not be ignored, because a large current will consume power on t...

Blocking effect The self induced electromotive force in the inductance coil always competes with the change of current in the coil. The inductance coil has a blocking effect on AC current. The size of the blocking effect is called inductive reactance XL, and the unit is Ohm. Its relationship with inductance L and AC frequency f is XL = 2 π fl. inductors can be main...
