How To Design Solonoid Coil for AC Voltage

In summary, you would need a coil with a resistance of 10,000 ohms and an inductance of 4,000 ohms for a coil with a diameter of 18 mm and a radius of 4 mm.

Hello Friends,

Can you help to solve the problem of my solenoid coil as before i created 12VDC coil & its working fine thanks for that help guys. but now i want 240 VAC solenoid coil. so can you please help me which SWG I have to select. how many turns have to select..i want the equitation how to calculate it.

Voltage is 240VAC
Ohms 10000

Thank You Friends

The current through an AC coil is limited by the coil resistance, R, and the coil inductance, L, in series.
Zcoil = R + j XL The reactance, XL, is proportional to power frequency, XL = 2 * π * fHz * L.

If you halve the cross section area of the wire, you will be able to wind twice the length on the former, the resistance will rise by four times, (half the area and twice the length), the inductance will also rise by four times since the inductance is proportional to the square of the number of turns.

You have specified “Ohms 10000” so I assume you want Zcoil = 10k
You must calculate the resistance and inductance of the coil for different wire diameters and solve for the diameter that gives the minimum cost of wire. Then √(R2 + XL2) = 10k

Thank you for your replay,

I would like to appreciate if you explain with an example.. because i m new & its very hard to understood. or give some link or document for reference.

My bobbin length is 18mm & radius is 4 mm

Again Thank you very much sir

FAQ: How To Design Solonoid Coil for AC Voltage

How does a solenoid coil work?

A solenoid coil is a type of electromagnet that is used to convert electrical energy into mechanical energy. When an electrical current is passed through the coil, it creates a magnetic field, which attracts or repels a metal plunger or armature, causing it to move. This movement can be used to activate or control a mechanical device, such as a valve or switch.

What are the important factors to consider when designing a solenoid coil for AC voltage?

The design of a solenoid coil for AC voltage requires careful consideration of several factors, including the number of turns in the coil, the gauge of the wire, the core material, and the frequency of the AC voltage. These factors will affect the strength of the magnetic field and the overall efficiency and performance of the solenoid.

How do I determine the number of turns needed for a solenoid coil?

The number of turns in a solenoid coil is determined by the desired strength of the magnetic field and the available power supply. A higher number of turns will result in a stronger magnetic field, but it will also require a higher voltage and larger power supply. The number of turns can be calculated using the formula N = (L x I)/B, where N is the number of turns, L is the length of the coil, I is the current, and B is the magnetic field strength.

Is there a specific wire gauge that is best for solenoid coil design?

The wire gauge used for a solenoid coil will depend on the specific application and the available power supply. Generally, a thicker wire with a lower gauge number will have lower resistance and can handle higher currents, resulting in a stronger magnetic field. However, using a thicker wire may also require a larger core and may be more expensive. It is important to choose a wire gauge that balances the desired performance with cost considerations.

Can a solenoid coil be designed for different frequencies of AC voltage?

Yes, a solenoid coil can be designed for different frequencies of AC voltage. The most important factor to consider is the inductance of the coil, which is affected by the frequency of the AC voltage. A higher frequency will require a larger inductance, which can be achieved by increasing the number of turns or using a different core material. It is important to choose a design that is optimized for the specific frequency of the AC voltage to ensure the best performance.
