Inductance coil for speaker
The inductance L represents the inherent characteristics of the coil itself and is independent of the current. Except for the special inductance coil (color coded inductance), the inductance is generally not specially marked on the coil, but marked with a specific name. Inductance, also known as self inductance coefficient, is a physical quantity indicating the self induction ability of inductor. The inductance of inductor mainly depends on the number of turns (turns) of coil, winding mode, whether there is magnetic core and the material of magnetic core, etc. Usually, the more coils, the dens
Toroidal Coil winding machine for produce Inductance coil 1
The coil is wound on the insulating tube by the wires one by one. The wires are insulated from each other, and the insulating tube can be hollow or contain iron core or magnetic particle core. The inductance of the coil is expressed in L, and the units are Henry (H), millihenry (MH) and microhenry( μ H),1H=10^3mH=10^6 μ H.
Inductance coil is a device that works by using the principle of electromagnetic induction. When a current flows through a wire,
The increasing sea fees affect toroical winding machine sells

Correct use of automatic soldering machine 2
Here's how to use it correctly.
1. Before using the automatic soldering machine, tin should be applied. The specific method is: heat the electric soldering iron, when the soldering tin can be melted, apply the flux, and then apply the solder evenly on the soldering iron head, so that the soldering iron head can eat a layer of tin evenly.
2. The solder joint of automatic soldering machine should be in the shape of sinusoidal wave crest, the surface should be bright and smooth, the tin content should be moderate.
3. In order to select suitable solder,

For many manufacturing entrepreneurs, the factors that have been bothering them are the market economy downturn, fierce competition among peers, high labor costs, recruitment difficulties and so on. Now more and more enterprises either transform and upgrade or change their operation mode and production mode. As an industrial power, countries all over the world have been calling on enterprises to change the traditional rough manufacturing mode, improve the level of industrial industrialization and informatization, and improve work efficiency. As an automation R &am
Working principle of inductor winding machine 2
When a closed circuit is formed, the induced potential will produce an induced current. According to Lenz's law, the total amount of magnetic lines of force produced by induced current should try to prevent the change of original magnetic lines of force. Because the change of the magnetic line of force comes from the change of the external alternating power supply, the inductance coil has the characteristic of preventing the current change in the AC circuit from the objective effect. Inductance coil has similar characteristics to inertia in mechanics, which is cal
Working principle of inductor winding machine 1
Inductive coil means that the coil is wound on the insulating tube by wires, and the wires are insulated from each other. The insulating tube can be hollow, and can also contain iron core or magnetic powder core. Inductor 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 of the electromagnetic field itself will induce the wire in the range of the electromagnetic field. So what is the working principle of inductor windi

According to the winding mode can be divided into: flat winding machine, ring winding machine, flying fork winding machine, three-dimensional winding machine. According to the actual work of the winding machine and the previous fault records, it can be found that the accidental fault caused by the design or production process defects of the winding machine can be solved by constantly modifying and improving the system software or hardware. These modifications are continuously provided to maintenance personnel in the form of maintenance information. Through these c

⑦ Inspection of insulation. The insulation ability of insulating materials varies with the degree of drying, so it is very important to keep the motor winding dry. The working environment of winding machine is humid and corrosive gas exists in the working room, which will damage the electrical insulation. The most common fault is the winding grounding fault, that is, insulation damage, which makes the live part collide with the metal part such as the shell that should not be live. This kind of fault not only affects the normal work of the winding machine, but also endangers personal safety.
