[@arismunadar7563]

@@InnovationKH The number 42 is a constant current or frequency ??

[@jaycool5978]

@@arismunadar7563 Its an constant when converting turn(s) to volts.

[@jaycool5978]

You'll first need to know how many cm/mm makes 1 complete turn. Some multiply height by width of 1 side (distance between inner and outer diameter). While others just use an measuring tape to get the exact length per turn. Then we use the constant value of 42 to convert volts per turn. Once we know how many turns per volt we multiply it by how many volts is intended for the winding. This tells us how many turns in total is needed. Finally we then need to convert the total number of turns into metres or feet since we need to wind up the shuttle we're going to use to do the windings. Also would need to know this as we may need to order the magnet wire for the job. Of course we need to know the gauge to gives us the amps too. We can find this out by looking up on an SWG or AWG table. Going back to the windings we need to work out 1 turn around the shuttle itself so we can do the same sort of Maths at the beginning. Once we need how many cm/mm is required per turn we then divide the total length required for the actual winding. So if the shuttle is 25cm and we need 35 metres we do 3000 / 25 = 120 turns. Add an little extra for error like a few metres or so. From here we know the exact length of wire we're about to wind on the core; so there is no need to really count the turns as we wind the core. But besides that, more importantly we have the right amount of wire needed for the winding. It be very bad thing to attach another wire to what's been winding as it needs to be consistent (Unless we want to tap it to have another voltage output/input).

[@ranjulatanayak584]

You should study the tx there very well and distinguish the window and crossectional area then know the power rating of the tx wrt it.then you could comment what a big mistake they all had done here is without mentioning it how they could determine the dimension of a core?

[@jaackmcmahon8757]

Most of the power that toroid xfmr can carry depends on flux density of toroid and primary wire diameter.

[@eddiemanuelitonavarro2622]

Suppose we need to start the calculation to the size of core and we want to design a transformer that function to what we expect? What ti start in calculating?

[@donnaankstitus7092]

This is so wrong! The rule of thumb TPV= 42/Ac (Ac = core cross section) is BS. The magnetic equation is B = (Vp x E+8)/ 4.44 X Np X Ac X f where B is the maximum usable core flux density in gauss, Vp is the primary high line voltage, Ac is the core cross section area cm sq, and f is the power line frequency. The figure 4.44 is a factor for sine wave excitation. B can range from 12,000 gauss for thick laminations (24 ga) to 17,500 gauss for thin (29ga) laminations. Tape wound toroids are made of even higher quality silicon steel with B max up to 17,800 gauss. Compare calculated numbers using this formula to the rule of thumb. I designed power transformers for 15yrs!

When you test the windings with the bulb can you use a DC power source or does it have to be AC?

Thicker wire=higher current capacity, but everything depends on tor. core flux density. That is THE key to any transformer design. it is all about the magnetic field density the transformer supports.

How do you wind in the single-phase (Live, Neutral, Earth). What determines which is what wire?

[@tayro7265]

The live and neutral are interchangeable. The earth would be connected to a shield made of a sheet of copper between the primary and secondary winding's. If your making an audio transformer do not use this as a ground source for the secondary side. Create a virtual ground. A shield is used to reduce hum, if you use this as a ground for the secondary it will not work, it will in fact make it worse.

Plz explain.. how to select wire gauge for primary & secondary winding

[@jaycool5978]

Selecting the gauge depends upon how much amperage your require. If you know the wattage and voltage but not the amperage. The simplest way to find out is to divide wattage/power by voltage. Once you know the amperage; you can then follow an AWG (American Wire Gauge ) table to find your required gauge. Or use equivalent. Best to keep to your own countries measuring form. Although many companies use the AWG topology. Going to how does 1 know, which gauge for primary and secondary. Lets say you need 12 volts at 5 amps. So we need to convert it to wattage. Wattage/power = 12 * 5 = 60. We don't yet know the amperage for the primary but we know the mains supply and the wattage. Amperage = 240 volts / 60 = 4 amps. All is let to do is account for the power loss during conversion. This we would need to get from the manufacture of the core. Rest depends upon the quality of the magnet wire you've used and also the quality of your craftsmen ship. Its an Toroidal Transformer so the loss is small. So if the total power is 60 we could bump it up by upping the amperage and voltage a little (On the secondary). Also use an multimeter and an ammeter. Also beware the PSU circuit will have loss too. Good idea to first check the power loss of the bridge rectifier, regulator and any transistors you may be using. But if the PSU is already existing and you know its expected wattage/power input or you don't need 1 e.g. using straight AC. Then no worries and happy days. On the Primary could simply ignore it or just add a little more amperage to compensate for the slight loss in power. Don't forget to test its the right voltage before going big picture. We wouldn't want it to overload. So what we could do is put a light bulb between 1 side of the mains and 1 side of the primary winding. If it lights up then its safe to say it needs a lot more turns on the primary. If it doesn't its about right a little too much. But we could replace the bulb for a multimeter, which would tell us by how much we are out (Note that many multimeters are often slightly out. Especially the cheap ones). PS there is also an slight power loss when the transformer is under load. So perhaps give it a little more volts and amps on the secondary and account for any above the required in your PSU board. Hope this helps you? Happy winding :D

Where you take 42 from?

[@aicisha]

"42" is just a constant number which was deduced by experiments made in the past. The bigger the number, the better. If you already have a transformer and you want to find out if it was made with "42/S" rule, you can measure the voltage of one turn, calculate the S (=cross section area) of the core and you calculate that number. If it is less than 40, the transformer is not good and it needs more turns for the primary.
