13mm Hole BFEC Dust Collector System Pulse Jet Valve Solenoid Coil

The connection mode of the solenoid coil can be divided into a lead type and a pin type.

Alternating current
The electrical resistance of an AC coil is lower than the resistance of a DC coil at the same voltage. With AC coils, the current is not only determined by the resistance of the windings, but also by the inductive resistance (reactance). The inductive resistance is largely dependent by the position of the core. The further the core is removed from the coil, the lower the inductance resistance becomes. This means that the current through the coil increases. The current is lower when the core is in the lifted position. As a result, the coil should never be connected to the power supply when the core is removed. The coil can produce too much heat and burn in minutes.

How to improve the Q value of the wound solenoid coil?

The quality factor Q is a weight parameter that reflects the quality of the coil. Increasing the Q value of the coil is one of the important points that must be paid attention to when winding the electromagnetic coil. So, how to improve the Q value of the electromagnetic coil? Let me introduce you in detail below.

According to the working frequency, the wire of the coil is selected. Inductors with short working and low frequency are usually fired with insulated wires such as enameled wires. The operating frequency is higher than tens of thousands of Hz, and in the circuit below 2MHz, the multi-strand insulated wire is used to wind the electromagnetic coil, which can effectively increase the surface area of ​​the conductor, so that the Q value is higher than the coil wound by the single wire of the same cross-sectional area. About 30%.

Use a high quality coil bobbin to reduce media loss. In high frequency applications, such as short-wavelength bands, due to the common coil bobbin, the dielectric loss is high. Therefore, high-frequency dielectric materials such as high-frequency ceramics, polytetrafluoroethylene, polystyrene, etc. should be used as the skeleton, and Winding is performed by the winding method.

Choose a reasonable coil size to reduce damage. When the winding thickness t, the winding length L, and the outer diameter D satisfy 3t + 2L = D, the loss is also the smallest. The coil with the shield is optimal when L/D = 0.8-1.2.

Select the diameter of a reasonable shield. Using a shield can increase the damage of the solenoid and reduce the Q value. Therefore, the size of the shield should not be too small. If the area of ​​the shield is too large, the volume will increase.
