Jun 26, 2019 · The transmitting coil would be the Tesla's bifilar pancake coil - I would just pick a random speaker wire and make as many turns as needed to approximate the outer diameter of the receiving coil. It is not clear, though, how to wind the double-stranded wire: two strands side-by-side on the same plane (left), or one strand on top of the other ...

Don't use bare wire as the current will flow across the coils (short) rather than around in a spiral. Get the spiral as tightly wound as you can and the entire coil should spiral in the same direction (clockwise). Your 'aTiny' microprocessor will probably need some help driving a coil. Where do you get '0.5A' from?

Feb 5, 2018 · The amount of flux entering the receive coil is paramount. If the receive coil is at 90 degrees to the transmit coil then there is zero flux entering the "mouth" of the receive coil and zero coupling. However, if your coils do not share the same common axis then there can be some benefit in using an angle to optimize the receive coil flux.

Feb 18, 2014 · A bifilar wound coil with the second winding used as the suppression device. This is not very practical since it adds significant cost and size to the relay. The suggested technique for relay coil suppression is to used a reverse biased rectifier diode and a series zener diode in parallel with the coil.

This means that if you have a multi-layer coil, then a major simplifying assumption you can make is that the adjacent turn capacitance is negligible compared to the layer to layer capacitance. If you have (let's say) a 10 turn layer, then the inter-layer space stores 100x the energy of the inter-turn space, volume for volume, and so dominates ...

Dec 11, 2012 · Having to wind an inductor, I was advised to do it "Two in hand". I understand it means using two wires connected at both ends. Do I need the same amount of turns ? Is the inductance affected (same

Nov 24, 2021 · \$\begingroup\$ @Aaron It would make a more efficient transformer, for certain definitions of 'efficient'. '. However, if the purpose of a Tesla coil is to generate a high voltage, and usually for making pretty sparks to ground, then it would make a fairly bad Tesla coil, as the output voltage would be half that of an equivalent secondary driven in the no

Oct 12, 2022 · The bifilar wind will reduce the self inductance which should help the most from your present example. So look for a core with a high initial permeability or low hysteresis, and wind bifilar with a heavier gauge wire or litz wire to increase your conductor surface area.

Jan 19, 2018 · Now if you are wiring a coil for 4 ohms, you need 307 m wire on the coil. Now calculate the length of one turn of wire on the coil. If one turn is 2 inches, for example, then you need 2000 turns for 4 ohms impedance. The coil is designed on ohms not watts. Watts indicate the capacity or load a coil can handle, which depends on the gauge of wire.

Either single core or bifilar or litz will produce the same magnetic field for the same current and, as I said in my answer less heat is generated when resistance is lower I.e litz or bifilar don't heat up as much compared to a single strand BUT if you are using dc it won't make one jot of difference if the net cross-sectional-area is the same ...
