Inductive coil refers to a coil made up of wires wound one by one on an insulating tube, with the wires insulated from each other. The insulating tube can be hollow or contain an iron core or magnetic powder core. Inductive coils are devices that operate using the principle of electromagnetic induction. When a current flows through a wire, a certain electromagnetic field is generated around the wire, and the wire itself will induce the wire within this electromagnetic field range. So what is the working principle of an inductor coil winding machine?
Inductive coil winding machine is a machine that generates alternating magnetic flux inside and around a wire when AC current passes through it. The ratio of the magnetic flux of the wire to the current used to produce this flux. When direct current passes through the inductor, only fixed magnetic field lines appear around it and do not change with time; However, when AC current is passed through the coil, magnetic field lines that change over time will appear around it.
When a closed circuit is formed, this induced electromotive force generates an induced current. According to Lenz's law, it is known that the total amount of magnetic field lines generated by induced current must strive to prevent changes in the original magnetic field lines. Due to the fact that the variation of magnetic field lines originally came from the variation of an external alternating power source, objectively speaking, the inductive coil has the characteristic of preventing current changes in AC circuits. Inductive coils have characteristics similar to inertia in mechanics, and are named "self induction" in electricity. Usually, sparks occur when the knife switch is opened or turned on, which is caused by the high induced potential generated by self induction.
In short, when the inductance coil winding machine is connected to an AC power source, the magnetic field lines inside the coil will constantly change with the alternating current, causing the coil to continuously generate electromagnetic induction. The electromotive force generated by the change in current of the coil itself is called self induced electromotive force. From this, it can be seen that inductance is only a parameter related to the number of turns, size, shape, and medium of the coil. It is a measure of the inertia of the inductor coil and is independent of the applied current.
