Toroidal Coil winding machine for produce Inductance coil 2

Main performance indicators: voice

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 the coil, causing the coil to heat or even burn out. Therefore, sometimes the electrical power that the coil can bear should be considered.

Inductance

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 denser the coils, the greater the inductance. The inductance of a coil with a magnetic core is greater than that of a coil without a magnetic core; The greater the permeability of the core, the greater the inductance of the coil.

The basic unit of inductance is Henry, which is represented by the letter "H". The commonly used units are milliheng (MH) and micro Heng( μ H) , the relationship between them is:

1H=1000mH

1mH=1000 μ H
