This software allows to calculate the following species of inductors:
In all variants, that are below, it's possible to calculate number of turns if inductance is known or inductance if number of turns is known
- Single layer close-winding air core solenoid
- 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 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 RF 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 toroid coil with round & rectangular cross-section;
- estimate 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);
- coil on the ferrite E-core;
- coil on the ferrite U-core;
- finding unknown permeability of a ferrite ring;
- recalculate any coil with ferrite or iron core by determining its AL factor;
- 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 toroid inductor at the radio frequencies with Q-factor & self-capacitance calculations;
- Bandspread capacitors calculation;
In what of an advantage of this software before analogs?
- The program calculates the inductance of different species of inductor design. It is possible to select an optimal variant, to use available coil-former or recalculate inductor to other dimensions.
- Coil64 allows to estimate Q-factor, self-resonant frequency and self-capacitance of RF single layer air core inductor.
- Coil64 allows to estimate Q-factor and self-capacitance of a ferrite toroidal inductor at the radio-frequencies.
- It's possible to estimate the length of wire what needed to wind one layer, multilayer coil and the coil on a ferrite ring.
- Results of all calculations are deduced in a common text box, from where they can be saved in a file or print out.
- For flat coil inductors on the PCB, the program prompts the optimal sizes for highest Q-factor.
- It's possible to use metric or inches as units of measurements.
- AWG or metric wire gauge support.
- The program is freeware.
- Multilingual interface support.
- The soft is multiplatform. There are versions for Windows, Linux, MacOS & Android.
