Wire Self Inductance Calculator This calculator will help compute the inductance of a length of wire. Don't have an AAC account? Create one now. In contrast, a loop inductance can be measured. A wire can be found in any circuit, and thus, it is important to know how much inductance it is contributing. The output inductance is presented in nano henries 10 -9 H. You can select the unit of measurement for the diameter and the length. To use this calculator, just enter the diameter and length of the wire. Note that self-inductance of a wire is often not measured since it is only a part of a circuit's loop. This tool is designed to calculate the inductance of a length of wire given its diameter and length. Calculate Headspeed with your mini VBar Governor.Even a simple length of wire can exhibit inductance, or rather, self-inductance. Setting up the Governor on your mini VBar.

Inches Centimeters Single-layer coil Multi-layer, multi-row coil Multi-layer, single-row coil The following inductance formula requires units in inches. Enter the coil length distance from first to last winding - see diagram. Select the measurement units inches or centimeters. Calculated Wire Length is the total length of wire required to wind the coil, and accounts for wire pitch.French version.Ĭoil Inductance Calculator To calculate the inductance of a single-layer, air-core coil: 1. Conductor diameter shown in the output data is the same as the Conductor Size input converted to the chosen units. No correction for proximity effect has been applied in this calculation.

L I is frequency correction due to skin effect only.Ĭopper wire is assumed. K M is Rosa's round wire mutual inductance correction. K S is Rosa's round wire self inductance correction.


Round wire corrections are not required for single turn coils. Corrected Inductance is the Current Sheet Inductance value with corrections for round wire and frequency included. Base Inductance is the value calculated from this formula. Multi-turn coils use Niwa's general formula for rectangular current sheet inductance. When entering conductor size as AWG, sizes larger than 0 may be entered as 00,etc. Calculation of enamel thickness is based on typical magnet wire used by hobbyists, and may vary slightly from the actual value due to different insulation temperature ratings which affects insulation thickness. If you are using standard enamelled magnet wire, you can check the Auto Calculate box, and the overall diameter for this type of wire will be calculated automatically, based on the conductor size. In addition, if you enter a conductor size d or overall wire diameter d i that is too large for the specified pitch or coil length, the pitch and coil length will be increased automatically to the close wound dimension. When you click the Calculate button, the pitch and coil length will be adjusted to appropriate values for a close wound coil. You still need to enter the conductor diameter. This field is optional, but makes it convenient to specify close wound coils. For single turn coils, you can leave this field blank.Ī field is provided for you to enter the overall wire diameter which includes the insulation thickness. Select the either Pitch or Coil Length from the pop up menu, and then enter the corresponding p or b value into the input field. The conductor diameter is either mm or AWG according to the units pop op adjacent to the conductor size input field.įor multi-turn coils, you may enter either the coil length or the winding pitch.

The units for all dimensions, except conductor diameter, are according to the pop up menu at the top of the calculator. Pitch p is centre to centre spacing between windings. See bottom of this page for detailed information and instructions. Note: This formula is suitable for both long and short rectangular coils, and will accurately calculate the inductance of rectangular loop antennas.

Refer to the following diagram for the definition of the input variables.įor circular coils refer to the Solenoid Inductance Calculator Page. Use this calculator to find the inductance of a single layer rectangular coil.
