Coil Diameter Calculator

Formula

The formula to calculate the Coil Diameter (CD) is:

\[ \text{CD} = \frac{\text{CL}}{\text{N}} - \text{WD} \]

Where:

\( \text{CD} \) is the coil diameter (mm)
\( \text{CL} \) is the coil length (mm)
\( \text{N} \) is the number of turns
\( \text{WD} \) is the wire diameter (mm)

What is Coil Diameter?

Coil diameter is a measure of the diameter of a coil formed by winding a wire or other flexible material around a cylinder. It is an important parameter in the design of springs, coils, and other similar mechanical components. The coil diameter can affect the performance characteristics of the coil, such as its stiffness and the amount of space it occupies.

Example Calculation

Let's assume the following values:

Coil Length (CL) = 100 mm
Number of Turns (N) = 20
Wire Diameter (WD) = 2 mm

Using the formula to calculate the Coil Diameter:

\[ \text{CD} = \frac{100 \text{ mm}}{20} - 2 \text{ mm} = 3 \text{ mm} \]

The Coil Diameter (CD) is 3 mm.
