Skeleton inductance coil winding method
The winding method of enameled wire on the skeleton can be divided into two types: single-layer winding method and multi-layer winding method.
1.Single-layer winding method: It is mainly to distribute the enameled wire in a single layer on the cylindrical surface of the line diagram skeleton.
There are two kinds of single-layer winding methods: inter-winding and dense-winding, and the inductance coils used for high-frequency resonant circuits are both interwound.
Law. This winding method reduces the intrinsic capacitance of the inductor coil and has a high figure of merit and stability. At.
The resonant coils used in the short and medium wavelength ranges are all tightly wound in a single layer.
Inductance. 
Inductance coil winding method with large inductance:
2.For coils with an inductance of more than a few hundred micro-hentons, multi-layer winding method is applied, and multi-layer winding method can be divided into two types: multi-layer dense winding and honeycomb winding
Multi-layer dense winding refers to the close arrangement of enameled wires layer by layer, and the distributed capacitance of this winding method is relatively large;
Honeycomb winding method: the turn-around is not balanced arrangement, but has a certain angle, this winding method distributes small capacitance, but the winding needs to use a honeycomb winding machine.
General high-frequency chokes, due to the requirements of large inductance and small volume, but the accuracy, Q value and stability of the inductance are not high, most of them use multi-layer dense winding.
For the inductance coil used in the resonant circuit that operates under high voltage and high power, when winding the inductance coil, it is necessary to consider the current value that the wire turn can bear and the withstand voltage between the wires, and at the same time, it is necessary to pay attention to the heating problem of the coil, and consider whether to use high-temperature wire or special wire winding.
Skeleton inductance coil winding method
The winding method of the skeleton inductance coil can be divided into two types: single-layer winding method and multi-layer winding method. The single-layer winding method is to distribute the enameled wire in a single layer on the cylindrical surface of the line diagram skeleton, while the single-layer winding method has two types: inter-winding and densely winding. Interwound inductance coils suitable for high-frequency resonant circuits, with high figure of merit and stability. Resonant coils used in the short and medium wavelength ranges are usually single-layer tightly wound. For coils with an inductance of more than a few hundred micro-yons, the multi-layer winding method is usually used, which is divided into two types: multi-layer dense winding and honeycomb winding. Multi-layer dense winding refers to the close arrangement of enameled wires layer by layer, with large distributed capacitance; The honeycomb winding method means that the winding turns are not balanced arrangement, but have a certain angle, and the distributed capacitance of this winding method is small, but it needs to be wound by using a honeycomb winding machine.
In addition, for inductance coils for resonant circuits that operate at high voltage and high power, it is necessary to consider the current value that the wire turns can withstand and the withstand voltage between the wires, and also pay attention to the heating problem of the coil, and consider whether to use high-temperature wire or special wire winding. During the production process, the following points also need to be noted:
1.Choose the right wire: Choose the right wire according to the specific application needs, such as copper wire, nichrome wire, etc.
2.Control the number of turns of the coil: Too many turns will increase the inductance and resistance of the coil, and too few will not achieve the desired amount of inductance. The number of turns needs to be determined according to the actual needs and experimental results.
3.Ensure the stability of the coil: In the production process, the stability of the coil should be ensured to prevent problems such as short circuit or open circuit between turns.
4.Consider heat dissipation: For high-power inductor coils, heat dissipation needs to be considered, and measures such as heat sinks or fans can be used to dissipate heat.
5.Test and adjust: After the fabrication is completed, the inductor coil needs to be tested and adjusted to ensure that its performance meets the requirements.
In general, the winding method of the skeleton inductor coil needs to be selected according to the specific application needs and actual conditions, and at the same time, it is also necessary to pay attention to the details and manufacturing process to ensure the performance and quality of the final product.
