I would like to suggest you to evenly distribute the secondaries along the entire circumference. Toroidal transformers are used to minimise magnetic flux leakages which interfere with an amplifier's sensitive input stage. Having secondaries unevenly distributed presents high reactive magnetomotive forces where turns are condensed and low where they are farther apart. This causes flux to leak.
Thank you very much sir for showing us this video... It is very informative for me. I would just like to ask what is the name of that material did you use in wrapping the core? Thank you in advance for your response.
সাবাস,,, electronics help care,,, আপনার কনটেন্ট গুলো অনেক সুন্দর হয়,,, আমি অবাক হয়ে গেছি,,, কথা না বলার পরেও,, এত সুন্দর বোঝানোর ধরন,, প্রথমে ভাবছিলাম যে, এটা হয়তো বাইরের দেশের কোন চ্যানেল,,,কিন্তু না,,, পরে দেখলাম এটা আমার বাংলাদেশের চ্যানেল,,,😍 খুব শীঘ্রই বাংলাদেশের Top 10 এর মধ্যে থাকবে আপনার চ্যানেল টি,,, ইনশাল্লাহ,,,,!!! আর যদি ভিডিও গুলিতে ভয়েস এড করা যায় তাহলে তো কোন কথাই হবে না,,, আপনার কাছে একটা অনুরোধ থাকবে,, লেখার পাশাপাশি ভয়েস এড করবেন,,,।
The core used is O-shaped, toroidal, ribbon (Type OL). Dimensions: "A" - 35 mm. (The width of the core core). "B" - 65 mm. (Core thickness or ring height). "C" - 75 mm. (Window width or inner diameter of the ring). The overall power of the core is 685.7 V / A. The cross-sectional area of the magnetic circuit is 22.8 sq.cm. The cross-sectional area of the “window” is 44.2 sq.cm. The approximate cross-sectional area of the windings is 24.7 sq.cm. >>> PRIMARY WINDING The mains voltage is 220 V. The number of turns of the primary winding - 267.0 The diameter of the wire for the primary winding is 1.26 mm. The current consumption from the network at maximum power is 3.12 A. >>> SECONDARY WINDING The total power of the secondary windings is 640.00 V / A. Winding No. 1 The set voltage is 40 V. The set current is 8000 mA. The number of turns - 48.5 The diameter of the wire is 2.021 mm. Winding No. 2 The set voltage is 40 V. The set current is 8000 mA. The number of turns - 48.5 The diameter of the wire is 2.021 mm.
A transformer is an inductive device for which current and voltage phase are shifted. That is why power rating of a transformer is expressed in VA, not watt. That core will saturate long before you ever reach 500 VA. If you spend so much time and effort in winding it, why don't you do a clean job? Spread the windings evenly.
Hi there, video is nicely made. But you did not show how to make core for the transformer. Is it bought out? Is all the sizes easily available in market?
In your site, you said that the primary and sec. were 17 gauge and 10 gauge respectively!! But here in the video, you are using 22 gauge and 18 gauge !! Do you mean that there is a wide range of flexibility in utilizing the size of wire?
Tem que fazer dois enrolamentos de 117V e deixar as bitolas de tape center, sem unir, isso é pra comutar com a chave H sim vc quer ligar em 127, ou 230V..
agar board kabhi bhi soart hoi ya phis samaj lo koin ek mosfet sort hua to fir yo 5 watt ka resister high amp ke bajh sey burn ho jata hain aur board ko bacha leta hai jease samjho tum 60.060 ka tranfomer use kar rahe ho to agar kisi karan ek mosfet sort hua to aur bhi sare component ko kharap hone ka khatra rehta hai
