(Delta Winding) Brushless DC Motor 

Terima kasih kembali, semoga bermanfaat..

Bedanya di rpm dan torsi. Saya ada baca beberapa refeferensi beda penjelasan. Jadi saya belum bisa kasih pendapat mana rpm lebih tinggi dan mana torsi lebih kuat.

Our thanks for your enormous effort and practical demo

My Q . A in servo motor winding . 18 slote 9 pole but 4 wire 3 phase dc ?

Perbedaanya bukan lebih panas atau dingin. Perbedaannya kalau delta rpm tinggi torsi rendah, star kebalikannya. Kalau lebih cepat panasnya atau lebih adem dari perbedaan besarnya kawat email yang digunakan. Kawat lebih besar rpm dan torsi tentu lebih besar dibanding kawat email yang lebih kecil. Kalau lebih cepat panas tentu desain bldc nya harus didesain untuk lebih mudah pelepasan panasnya, misal ditambah sirip2 pendingin dan kipas. Atau kawat emailnya didesain lebih tahan suhu tunggi alias tidak mudah terbakar.

Tidak mas, satu arah saja...

@@YudiHermanto4H aq dah coba buat yg 8 kutub mas pake bekas pompa air, ketika start running k tersendat sendat g bisa langsung muter, kira2 salah apanya ya mas

@@ahmadmoeklis6127 8 kutub apanya ? Rotornya ? Pompa air kan kern/statornya 24 kutub, itu pke 16 kutub di rotornya. Lilitan satu arah. Bisa juga pakai 14 kutub, tapi beda lilitanya. Itu ada di video saya, coba dicari, mas.

@@YudiHermanto4H ok, makasih mas,

Bisa mas.

Kutub magnetnya ada berapa mas, 4 kutub magnet ?

@@YudiHermanto4H 6 mas

@@projectbahagia 6 pole magnet, berapa coil statornya ?

@@YudiHermanto4H minta tolong samean wa aja ya mas ta kirim fotone

@@YudiHermanto4H soale uda nyoba 3 hari belum berhasil, ini aslinya motor brushless 310v trs modif jadi 12v

For low rpm and high torque, use DELTA winding, but for high rpm and low torque, use STAR winding..

Star, mas. Star, torsi tinggi tapi rpm rendah. Sebaliknya dengan delta.

Sorry I was too late to respond to your question. The more poles, the lower the rotation, but the greater the torque. The fewer the poles, the higher the rotation, and the torque decreases. For the type of connection is not much different. It's just that the star rpm connection is higher than the delta connection. So, for low rotation with large torque, it is more effective to increase the number of poles.

@@YudiHermanto4H Then I will make a delta connection on my generator with fewer poles. Thanks for replying, friend and congratulations on your channel, it's great.

@@motoresesistemasautomatos. Ok, the important thing is the number of poles has a multiple of three.

@@motoresesistemasautomatos. And every three stator poles have / are faced with two magnetic poles.

@@YudiHermanto4H Thanks for the precious tips. I have been looking for a method of investing in my grater and making it more efficient, I believe that with your tips there will be a good improvement in the final result. Thank you my friend.

Kalau delta lebih cenderung torsi besar tapi RPM rendah dibanding star. Kalau star RPM yang tinggi, torsi rendah.

@@YudiHermanto4H terimakasih banyak gan ilmunya🙏

Belitan bintang lebih tinggi kecepatanya dibanding belitan delta. Even though the delta winding has a lower speed, it has stronger torque. If you want to increase speed, replace the diameter of the larger enameled wire.

@@YudiHermanto4H it doest matter if it is delta or star? I just need to replace larger wire for speed? Larger wire means fewer turns right?

Yes, but the difference in diameter of the wire should not be too far. For example the original diameter is 0.5mm, use 0.7mm or 0.8mm.

@@YudiHermanto4H wait I got confused, I though star or wye is for torque and delta is for speed. My motor is in star or wye, it got good torque but slow in speed, my plan is to convert it in delta, but you said just replace the winding with thicker wires. Does it mean bigger wire in star or wye connections? Thanks for replying by tge way.

​@@dingski_diy Actually the difference in torque or rotation at the star and delta connections, is not too much different. What is very clear is the difference in the number of poles. The more poles, the lower the speed, but the greater the torque. And vice versa, the less the number of poles, the higher the rotational speed, but the torque decreases. So, if there are many poles and you want to increase the speed, replace the larger wire diameter.

Iya, Kalau kawat dibesarin otomatis jumlah lilitan berkurang. Tapi paling tidak controller nya ikut di upgrade mas. Terutama spesifikasi mosfet dinaikan. Bisa ganti mosfet yang lebih besar atau mosfet ditambah diparalel.

Sama2 mas, terima kasih sudah berkunjung ke channel saya.

Dibesarkan saja diameter kawat emailnya, jumlah lilitan otomatis jadi lebih sedikit. Kalau jadi lebih cepat panas itu wajar, tinggal proses pelepasan panas/proses pendinginan diperbaiki. Kalau brushless yang high speed rata2 menggunakan kawat email besar dan cepat panas, makanya bodi menggunakan aluminium dan ada juga yang menambah sirip2 pendingin.

Kalau sebelumnya delta di rubah ke star nambah berapa rpmnya pak. . .dan cepat panas mana antara sistem sambungan delta dan star

@@efendiayik1769 sambungan delta rpm lebih tinggi tapi torsi lebih rendah. Sedangkan sambungan star rpm lebih rendah tapi torsi lebih besar. Lebih cepat panas dan tidaknya, setahu saya, pengaruh dari diameter kawat email dan suplai tegangannya.

Trmksih pak🙏🙏

@@efendiayik1769 sama2 mas bro...

Maksudnya ? Lilitan generator ataupun motor tiga phase, konfigurasi sambungannya ada dua..delta dan star.

Bldc 3 phase sama delta itu efisien mana

for three-phase turns, it is usually sams.

6 or 12 magnets also can. If it is 6 magnetic poles, the rotation speed is higher than 12 magnetic poles.

@@YudiHermanto4H thanks. If 12 magnetic poles torque will be higher?

@@MasterTv_777 Yes, the more poles the bigger the torque, but the lower the speed. Vice versa, the less the pole the smaller the torque, but the speed goes up.

sorry, I don't know the exact formula. If it gets too hot, just shrink the wire size. 😁🙏🙏
