Enameled wire- how to strip? | Forum for Electronics
2004年6月3日 · Saying that, I 'have' tried this, outside, and it didn't seem anymore effective than running the enamelled wire over a hot flame and wiping with a damp rag. Also, soldering with extra flux seems to work well, the iron burns the enamel, and the flux takes it off the wire. Also tin's the wire for easy soldering later. Buriedcode.
Multi stranded non-enamelled wire...skin effect?
2021年6月10日 · 8,738. the whole point of using multi-stranded Litz wire is to conduct in all of the copper. because of skin depth at high frequency. if the strands are not enameled (insulated), you may as well have a solid conductor. the enamel forces the current to stay in their strands. without the enamel, the current can move to the outside and the Litz ...
Multi stranded non-enamelled wire...skin effect?
2021年6月10日 · All multi-strand cables are twisted and that too has some effect (with a tight twist, each strand acts like a solenoid). When wound in the bobbin, it introduces another layer of complexity. The magnetic core will also have some effect on the distribution of the magnetic field. The simplest solution is to experiment.
Tape between enamelled copper wire layers in Flyback SMPS …
2021年6月13日 · Our 24V input to 24V, 2A 150kHz isolated flyback works fine with the primary wound as two layers. of enamelled copper wire. (PQ20/16 bobbin) Ns/Np = 15/10. The secondary sandwichs the primary with series windings of 8 turns and 7 turns. (triple insulated wire) The primary 10 turns are comprised of 2 layers of 5 turns (3 strands of 0.315mm ECW) .

Thickness of wire in SMPS transformer? | Forum for Electronics
2011年6月13日 · Originally , i specified 84 turns of (2*0.5)mm enamelled copper wire.....-in 4 layers (-thats two strands of 0.5mm enamelled copper wire acting like "one" wire) However, the transformer manufacturer came back to me and said that i should just use 84 Turns of 0.7mm TEX-E triple insulated wire.....this has an inner conductor diameter of 0.5mm ...
Soldering station on Atmega8 with 7-segment display
2011年8月2日 · In this project, an old transformer with the following parameters: 12V 50VA was used. It can be easily disassembled and re-wound (it consisted of EI core (plate E and I)). The old secondary winding was removed and a new one was wound using a thinner enamelled wire. Also another winding 6V was added using a thin enamelled wire to power the ...
[SOLVED] 12 vdc led running very hot - Forum for Electronics
2019年7月11日 · You can get the LED voltage (called Vf) from its data sheet or measure it with a meter. Note that it stays fairly constant when the current changes. Looking at Prairiedog's calculation, Vres is 13.8 - 1.8 = 12V. 12 squared is 144. The power it dissipates is therefore 144/510 = 0.282W.
Gate drive transformer wound bifilar or interleaved.
2012年9月23日 · 31,695. I am not sure that you can get "enamelled " copper wire any more. If you can don't touch it. Get a modern coated wire such as Bicelflux or its equivalent. Real enamelling comes off very easily because its so brittle. While bifilar is very effective in keeping the leakage inductance down, I really do not think there is sufficient safety ...
