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.
