Very simplified explanation and I understand now how to make my own inductor coil for my crossover dividing network for my Kenwood speakers.....

What about, in AC induction motor. How can we find the required number of turns

[@technologiesdiscussion1676]

To be frank, I am not so sure abt AC induction motor. I dun want to give you any wrong info.

Very helpfull to make pasif crossover audio

[@technologiesdiscussion1676]

Thank you for your suggestion. Frankly, I do not know how to do it. :)

Calculation is not working, i can't understand what value in 25.4 ? And 22.9 My Inductor is 3 mH Drum bobbin indcutor Dia 8.67MM coil length 7.5MM So how can i calculate turns? And when i calculate your formula with my calculator but value are different so pls can you explain in easy with calculator

[@technologiesdiscussion1676]

Thank you for your question. 25.4 and 22.9 are just constant numbers. You can just calculate it as per normal. I just want to check your values. Are u really going to coil the inductor? The length is 7.5mm and it seem very difficult to coil even for 1 turn because the length is too small. Thks.

[@ronakparmar6717]

@@technologiesdiscussion1676 Suppose that when one inductor coil are 3mH [0.003H] so how many turns in coil? When I put your formula in my case but resul is so deferent. So I request you make a one video bobbin drum inductor coil in details

[@technologiesdiscussion1676]

@@ronakparmar6717 Thank you. There is a different. Bobbin Drum inductor is winding to the magnetic core. While the formula introduced in my video is winding to the air as medium. Therefore, the formula are different.

@@ronakparmar6717 I will find the formula but may take some time. :)

In 4B, the equivalent circuit for inductor is R and L in series. In this lesson, 4C, the equivalent circuit is in parallel. Please explain.

[@technologiesdiscussion1676]

Equivalent circuit of an inductor as shown in 4C is presented as R & L in series. However, I can also express the R & L in parallel. In simple word, Rs is not equal to Rp. I convert the R value base on my use case. Thank and I hope i ans your Qns. :)

Formula doesn't consider wire diameter, which is not specified in any event.

When determining the values of an inductor, such as its inductance, in many practical cases, the physical size of the coil is often omitted or not explicitly specified because the inductance primarily depends on other factors. The key factors that determine the inductance of a coil are: Number of Turns (N): The inductance is directly proportional to the square of the number of turns in the coil. Increasing the number of turns increases the inductance. Cross-sectional Area (A): The cross-sectional area of the coil also affects the inductance. A larger cross-sectional area generally leads to higher inductance. Permeability of the Core (μ): If the coil has a core (ferromagnetic material), the permeability of the core significantly influences the inductance. Higher permeability materials result in higher inductance. Length of the Coil (l): The length of the coil is inversely proportional to the inductance. Longer coils generally have lower inductance. The physical size of the coil, such as its length, diameter, and shape, influences factors like the self-capacitance and resistance, but these are often considered separately from the inductance itself. In practical applications, when specifying an inductor, you may see details about the core material, the number of turns, and the wire gauge used, but not necessarily the physical dimensions of the coil itself. Engineers and designers focus on the parameters that directly impact the inductance and its behavior in a circuit.
