spiral_counter_clockwise.pdf - 47KB, PDF file. Calculate Turns JAVATC performs millions of iterations for accuracy during the total system computations (it takes time). There are two electrical connections to be made to the primary coil; a fixed connection at one end of the coil and a movable tapping point, to connect to any point on the coil. I have a primary coil already setup, but I … Power is supplied to the primary circuit through a transformer, which charges a capacitor. If the current in the primary coil is 4A, then the current in the secondary coil is : A. Primary Coil Hypotenuse = (Primary Coil Wire Diameter + Primary Coil Wire Spacing) × … JavaTC Tesla coil calculator. Mine was a different case. How to find the right secondary coil form material Plastic materials all react differently in a high frequency electromagnetic field and thus some plastics are more suitable to use for a secondary form than others. Any changes that make this the number of turns.

Notice that I left a length in the middle for connecting to the The diameter of the inner-most turn is 2 inches greater than the diameter of the secondary coil, and it spirals out keeping a 1/4 inch gap between adjacent turns.

You won't need any extra wire sticking out at this end. Convert values to your unit as necessary. This copyright protected material has been illegally used without the permission of the owner. With the power supply listed above (15kV) and using a static spark gap, the primary capacitance (MMC) should be about 8.6nF (calculated with the TeslaMap program). It will also indicate the minimum number of turns required in the primary coil. Basically, it's a coil of copper pipe, wound in a flat pancake spiral.

the center of the coil.

The last detail is to use some nylon nuts & bolts to join it together. There are two ways you can tune the coil to get better results. The ring diameter refers to the ring in a toroid shape. The primary is driven with 340 volts, so the secondary will have 340V x 300 = 102kV across it.

You can also get plastic from hobby stores. In the past it was thought that the secondary coil wire length should match the quarter wave length of the Tesla coil's resonate frequency. coil. If you use multiple top loads, add their capacitance to calculate the total secondary capacitance.

Due to manufacturer variations in insulation, measuring wire dimensions with a caliper is preferred over any wire table.

The roll of pipe I bought was 10m in length, giving me 9 and a bit turns (ID of 8" to clear 6" secondary). This is what enables us to tune the frequency of the primary tank circuit to match the natural resonance of the secondary circuit.

Keep cool and don't rush! places (explained more below.).

Then use some more tape to tape that down onto wire.

The wire table for secondary coils list inches. Secondary Coil Wire Length (ft) = (Secondary Coil Turns × (Secondary Form Diameter × pi)) ∕ 12. This is what enables us to tune the frequency of the primary tank circuit to match the natural resonance of the secondary circuit. The following equations will calculate the dimensions of the primary coil and the inductance of the coil at each turn. As shown in the photo below, use the one that's in the opposite direction as your secondary When we change the number of primary turns tapped, to alter the frequency, we do not what to change the coupling as well (coupling is adjusted by changing the height of the secondary). " Secondary Coil Inductance" = 78822.3815. // -->.
