How to rewind a brushless dc motor, 9 pole stator and 8 or 10 pole rotor. 

Iya mas, sama/satu arah semua.

@@YudiHermanto4H oke pak saya coba besok.. trimakasih hehehe..

Iya mas, kalau empat biji pasti mantap 😂

I've never tried the LRK one. However, on a forum there are those who think LRK is better. LRK is more suitable for long stators, and dLRK for short stators. That's his opinion after trying to change the 12N14P dLRK brushless motorbike to LRK. Because (in his opinion again), LRK has more space to wind the wire.

@@YudiHermanto4H i'm making one 12 Pole bldc motor (outrunner type)....to make a diy cooler ....the rotor size (diameter ) about 12cm ....and i want the speed of 2500 rpm...i have 12v 10A power supply to run it...for which winding i should go ......DLRK or LRK .....please reply me....sir

Of course, the efficiency of the motor will not be maximized. For example, if the efficiency is good, you will get 15000 rpm, because the efficiency is not good, you will only get 14000 rpm. That's just an example. Many things affect efficiency, some examples are the stator material, the magnet used, the distance between the magnet and the stator.

@@YudiHermanto4H thanks for that. I ask because i rewound a small generator on a kubota style generator (it had burned) Single pole round magnet. When I took the old windings off, I was surprised to see that a; the windings alternated direction (I understand that now, thx to your video), and b; the windings were close, but not the same and one was considerably smaller. . What would happen if, for example, i had replaced each coil with half the number of windings?

Sebenarnya DC, tapi outputnya berubah-ubah secara bergantian antara 3 output. Misal 2 output positif, satunya lagi negatif. Tapi diatur sedemikian rupa dengan mendeteksi posisi magnet pada rotor sehingga di koil stator terjadi medan putar untuk memutar rotor.

complete in this video.

Saya belum pernah lihat dinamonya 😄

@@YudiHermanto4H 4 magnet rotor Dan 17 lobang stator. Saya coba gulung 3 fase tp gamau berputar

@@RayyanSaputra-r2s motor brushless 3 phase, jumlah lobang harus habis dibagi tiga, atau jumlah nya kelipatan tiga. 3, 6, 9, 12, 15, 18, 21 dan seterusnya. Kalau 17 lobang berarti tidak bisa.

@@YudiHermanto4H tp bawaannya ada 4 fase mas 1&3 lilitan arahnya sama 2&4 lilitan nya berlawanan dengan 1&3 bisa berputar pke controller 48v cuma putaran pelan tp torsi kuat

@@RayyanSaputra-r2s mesinnya seperti di video ini atau bukan : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Oj1-YVz0uZ0.htmlsi=6ge2hhZtHfSfUbIT

Iya bener mas. Kalau ada modulnya pengin coba, tapi harganya lumayan 😀

If there is a transmitter and receiver module, it can be done. To make the video, I don't have the transmitter and receiver module yet.

Will the receiver module not burn with this kind of motor.

Kalau hitung dari nol saya tidak bisa. Saya biasanya pakai perbandingan. Kalau misal aslinya pakai 12V, hitung jumlah lilitan originalnya. Kalau misal mau naik ke 48V, berarti naik 4 kali. Maka jumlah lilitan naik kisaran 4 kali juga. Otomatis diameter kawat diperkecil.

ESC atau driver nya.

Itu motor brushless bekas dvd room komputer. Kipasnya bisa pakai bekas kipas yang ada di power supply komputer.

@@YudiHermanto4H oh....!!! CPU lawas ya..?? Ah kebetulan sudah tersedia 😊😊😊😊

@@lelegokiltjchannel6561 yang penting ada dvd room nya. Dia pemutar dvd atau cd.

@@YudiHermanto4H ada mas...!!

Stator nya ya ? Tidak bisa, mas. BLDC 3 phase jumlah pole stator harus berjumlah kelipatan 3 atau habis dibagi 3. Kalau yang tidak habis dibagi tiga hanya bisa untuk satu phase. Tapi BLDC satu phase kurang bagus mas, dan driver/controller nya berbeda.

Itu untuk ketentuan pada stator kan ya mas kelipatan/dibagi 3 kalo untuk magnetnya gmn mas adakah ketentuannya juga mas

please try first.

Tidak mas, memang jarang online. Tapi sehari tetap cek wa sesekali.

Pn wa mas coba

@@efendiayik1769 silahkan mas..

Nomer.e pn hilang mas pn wa dlu
