More detailed about Coil64

The Coil64 program is a 64-bit cross-platform open source application. The use, modification, and distribution of the application and the source code is governed by the GPLv3 license. The application is available only for 64-bit desktop Linux and macOS and for 32-bit or 64-bit Windows.

Minimum system requirements:

• RAM: 1024 MB or more;
• Screen resolution: 1152×854 or higher;
• Required disk space: 25 Mb;

In addition, the calculations and the source code of the Coil64 are synchronized with the Coil32 app for Android. You can download the desired Coil64 distribution from the download page.

The current version of the Coil64 allows you to calculate the following types of inductors:

• Single layer close-winding air core solenoid
  As the initial parameters, you can choose two options:
  1. The former diameter and the wire diameter are known, the length of the winding is to be calculated.
  2. The former diameter and the winding length are known, the wire diameter is to be calculated.
• Single layer RF solenoid with winding pitch
• Single layer RF solenoid winding with rectangular cross-section wire
  
• Single layer RF solenoid with pitch, but non-circular winding
• Multi-layer air core inductor
• Multi-layer air core coil with sectional winding
• Multi-layer air core inductor with insulating pads
• Multi-layer air core inductor on a rectangular coil-former
  
• Multi-layer foil-wound coil
  
• Coil or choke on a ferrite ring (only for low-current circuits)
• The planar PCB coil
• Tesla flat spiral coil
• The software has additional modules that allow to calculate:
  • flat PCB coil with the meander form of turns;
  • search coil for a metal detector;
  • a single triangle, rectangle, or round loop coil;
  • air core toroidal coil with round & rectangular cross-section;
    
  • estimate the influence of the shield on the value of coil inductance;
  • ferrite rod core inductor;
  • coil or choke in the pot core (ferrite or powder iron, only for low-current circuits)
  • coil on the ferrite E-core;
  • coil on the ferrite U-core;
  • coil on the ferrite RM-core;
  • finding unknown permeability of a ferrite ring;
  • recalculate any coil with ferrite or iron core by getting its A_L factor from the measurements data;
  • Amidon™ cores: iron powdered & ferrite toroids, Pot-shaped, E-shaped & multi-aperture ferrite cores;
  • An optimal multilayer coil for the audio system filter (crossover);
  • A ferrite toroidal coil at the radio frequencies with Q-factor & self-capacitance calculations;
  • Bandspread capacitors calculation;
  • Calculator of mutual inductance of two coaxial coupled single-layer coils and tapped air core coil;

Support and update of Coil32 application is discontinued.

App Coil64 is multilingual. The application interface is available in the following languages:

You can also add to the app your native language. To do this, download the translating file of the app, add the translation after equal sign and send me via email. Email you can find in the “About” window of the app.

Also you can help to translate the app by the CROWDIN TRANSLATION PROECT.

You can configure the application by opening the “Options” menu item. In the first tab you can select the units of inductance, capacitance, frequency. Centimeters, millimeters, inches, and mils are available as units of size. You can select the calculation accuracy as the number of decimal places. You can choose to set the wire diameter by size or as an AWG number. In the second “Options” tab, you can select the application and output field fonts. In the third tab, you can check for program updates and set automatic updates.

Application settings

You can customize the display of text in the results output field depending on your wishes. This can be done both in the “Options” window and using the toolbar buttons above the output field in the main program window. Depending on the combination of settings, it is possible to display either detailed results with numbering, headings, descriptions of values and images, or a compact tabular one with color digital values. The color can only be changed in the “Options” window.

In the main window of the app, you can select the desired type of inductor, and then enter the necessary parameters for the calculation. In the first tab “Coil”, it's available to calculate the number of turns depending on the required inductance. In the second tab “Inductance”, it's available to calculate the inductance of the coil if you know the number of turns. In the third tab “LC circuit”, it's the calculation of the resonant frequency and other parameters of the LC circuit. Also, additional calculations are available from the main menu of the Coil64. All calculation results are displayed in a common output field from where they can be copied or saved to an HTML, ODF or PDF file, as well as printed.
