Fin is input frequency
Secondary Capacitance (pf) = (0.29 × Secondary Wire Winding Height + (0.41 × (Secondary Form Diameter ∕ 2)) + (1.94 × sqrt(((Secondary Form Diameter ∕ 2) 3) ∕ Secondary Wire Winding Height)). Note that the cardboard tube you see in the photos below is there just Of course, the TeslaMap program can quickly and easily calculate the dimensions and inductance of the coil out to 100 turns. This is a fairly typical Tesla coil design using a static spark gap, which should be a good starting point for a small to average sized Tesla coil. I was in a bit of a hurry with making my strike rail and had to go with what materials I had lying around. Tesla Coil Theory by Terry Blake http://www.tb3.com/tesla/theory.html, Richard Burnett's page http://www.richieburnett.co.uk/tesla.shtml. Primary Resonate Capacitance (nF) = 1 ∕ (2 × pi × NST Impedance × NST Fin) × 1,000,000, Primary LTR Static Capacitance (nF) = Primary Resonate Capacitance × 1.618, Primary LTR Sync Capacitance (nF) = 0.83 × (NST Iout ∕ (2 × NST Fin) ∕ NST Vout) × 1,000,000,000.
This calculator will equate all linear geometry's (flat, helical, cones, and inverse cones), closewound or spacewound.
I wanted to try a spiral shaped primary coil with my small spark gap ( Log Out / Here's how. Secondary Height Width Ratio = Secondary Wire Winding Height ∕ Secondary Form Diameter. There's not a lot you can say about my primary coil. But even a relatively short coil with 1000 turns, stressed to 500 kV would only have 500 V between turns. 2000 turns) and a primary coil which contains few turns of a thick wire. It has to be worked out such that your I've found several equations for different sized top loads. self.backto_related_material(0); and striking the primary coil (see the 'Gallery' for pictures). You do not need to be exact in the initial forming of the spiral but once you have it flat you can then go round making small adjustments. I used a short piece of 10mm copper pipe soldered to the inner turn end to make the fixed connection. With the aid of soft cotton gloves I carefully smoothed the pipe into shape. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. It's a good idea to double the peak voltage rating to about 40kV. It was designed to take 6.3mm diameter fuses but with a bit of careful bending with pliers, a good connection to 8mm copper pipe is possible. there's around 1/2 centimeter spacing between the turns. The roll of pipe I bought was 10m in length, giving me 9 and a bit turns (ID of 8" to clear 6" secondary). It consists of little more than a wire ring, positioned just above the outer edge of the primary coil, with one of its ends connected to the RF ground. The wire table for secondary coils list inches. The secondary LC circuit resonate frequency will be used to calculate the amount of primary coil inductance required to tune the Tesla coil. The number of turns in primary and secondary coils of a transformer is 50 and 200 respectively. After running the coil a few times Refer to the secondary coil construction section to define small, average and large. The overall diameter refers to the widest length from edge to edge of a toroid shape.
They are, in fact, the ends of the primary coil which I trimmed off to remove the overhang! Although this purpose was never realized due to its impracticality and inability to turn a profit; the physics involved in the tesla coil is truly remarkable. These calculations will be used to determine the optimum sized primary capacitor (in the next section). Magnet wire is typically sold by weight, so it's important to know the required wire weight.
After the inductance is calculated for each turn on the primary coil, we can use the "Needed Primary Inductance" value to indicate the proper turn where we should tap the primary coil. Once you've downloaded it, adjust the size before printing it such that This is what I will be using to support the tubing. The primary winding has six turns and the secondary has about 1800 turns. The total number of turns required depends on the values of the other circuit components, but a maximun of 15 turns would be a good number. I allowed the wire to wrap itself around the peg, effectively shortening its length 16mm for every revolution (the peg was 5mm in diameter). and how to tune it, along with a few demonstrations of it in action. 2000 turns) and a primary coil which contains few turns of a thick wire. Next, I cut and drilled the supports for the primary (I made a little jig to help with the drilling).
sticking out at this end. For a more detailed description I recommend the following resources: The Tesla Coil by Chris Gerekos An alternating current is applied to the primary coil, and due to Faraday’s law of induction, a current is induced in the secondary coil. Usually, Tesla Coilers have to find the perfect number of turns to tap the Primary Coil at. Convert values to your unit as necessary. Change ), You are commenting using your Facebook account. coil.
distance longer is an improvement. The primary coil is also responsible for transferring power to the secondary coil. Please visit www.teslacoildesign.com for the original and most recent version of this material. The rail itself is made of 10mm copper tubing (available from DIY plumbing stores) and you might recognise the supports already. The height to width ratio should be about 5:1 for small Tesla coils, 4:1 for average sized Tesla coils and about 3:1 for large Tesla coils. Secondary Coil Wire Length (ft) = (Secondary Coil Turns × (Secondary Form Diameter × pi)) ∕ 12. You won't need any extra wire sticking out at this end. This quick calculator is available for coilers who need to equate the number of turns, radius, height, etc.
The following equations will calculate the dimensions of the primary coil and the inductance of the coil at each turn. The power supply is a high voltage transformer used to charge the primary capacitor. I have a primary coil already setup, but I … Leave one end unconnected and bring the other one down for connection to ground. wire extending from the center of the spiral coil together. I used a short piece of 10mm copper pipe soldered to the inner turn end to make the fixed connection.
with the sticky side facing up.
Basically, it's a coil of copper pipe, wound in a flat pancake spiral. Too many turns, or too little, resonance will not be achieved. For starters, I have a 6 inch ring diameter by 19 inch overall diameter Toroid for the top load. Due to manufacturer variations in insulation, measuring wire dimensions with a caliper is preferred over any wire table. Two are given and the difference is in the directions the turns
