As a result, Orthocyclic wound coils with a round coil ground are never circular in the cross over section, but the radial moving winding and layer step creates a hump shape. Experience has shown that depending on the winding width, coil and wire diameter, the crossover section is about 5 to 10 percent higher than the regular winding height. Ideally, the winding should be positioned parallel to the winding flange, meeting an orthogonality condition. It is necessary to adjust the winding width to the number of turns per layer of the winding.
For non-circular shaped coil cross-sectional areas, it is preferable to locate the crossover area to the small side of the coil body, also called winding head. This is because the non-circular coils are being mounted on a sheet metal package or in a circular arrangement. The coils should be rather small, in order to avoid a contact with the neighboring coil or the sheet metal package. The choice of the winding structure to be used basically depends on the design of the coil or the coil body.
Among others, the available space conditions for winding width and winding height must be considered. Moreover, it is possible to influence the location and the end of the last winding by selecting a clever winding pattern.
The winding height of an Orthocyclic coil winding results from the following equation:. This winding method reaches the highest fill factor and is the best way to fill the available winding cross-section with round wires. Square coils are seen as Orthocyclically wound when the winding and layer jump occur only on one of the sides of the winding cross-section. In theory, a geometric fill factor of 0. In practice, however, the value cannot be reached because there exists a winding jump and layer jump area and the wire insulation is not taken into account.

Here's a useful and general "slide" taken from the Ferroxcube soft ferrite handbook: -. Skip to content coil impedance inductance reactance transformer I need to know the number of turns that should be connected to volts AC. Thank you very much,. Best Answer. Now estimate the area you have available to put those turns into.
Divide your area by the number of turns you need. That's the area of the wire you have room for. Multiply it by 0. Get a wire table the ARRL handbook has one, there may be at least one on some forgotten corner of the Internet, somewhere. Find a wire size that has the area you need. Get some, and start winding. And do not be upset if your calculations are way off the first time around -- that just means you're an engineer. Sign up to join this community. The best answers are voted up and rise to the top.

So the system dumps a bunch of mechanical energy into the projectile so the whole thing can finally reach that minimum energy state. Anyway, back to the number of turns question. Which is also related to the wire size. I haven't been able to identify all the variables and equations that need to be optimized. This is all such an iterative process.
But I think it's really a matter of maximizing turns and maximizing coil current, until you run into some practical limitation. Here's a few limitations that occurred to me:.
Once this gets too high, the coil can't dissipate the heat fast enough. You can get around it a little bit by reducing the duty cycle, but eventually the wire melts during a single shot. For that reason, thicker wire is better.
