I have a few broken computer fans. Fixing them is difficult. Today, I will build a simple yet powerful control circuit for the computer fan. It only uses 2 mosfet and 4 resistors. Very simple for newbies. Facebook group : bit.ly/CreativeElectronic
@@PhdHung Can you tell the both the Mosfet no# as in the diagram it's not clear visible ? What is the DC voltage and amperes applied? And i have similar speed fan but with only two wire coming out ? ( manufacturer name shengshida )
Tuyệt vời quá.mình có 4>5 cái quạt loại amper cao mà bị hư bo có cách này thì mình cứu nó sống lại thì có đồ chơi rồi kaka. Giữ lại bo khiển của quạt lấy hết linh kiện ra,lấy fet trong main cpu vi tính có đủ loại mà nhỏ gọn nữa,gắn linh kiện vào mạch của quạt thì y như zin lun.
Nice to see a video of someone who actually knows how to use a soldering iron, & knows what's he's doing.... Nowadays anybody with a camera starts making shitty videos with fake thumbnails & clickbait titles. Keep up the good content ☺️✌🏻👍🏻👍🏻
Thanks very much for show all , nice video , i see all is very easy for me thanks for you , I like to much your videos , teacher , greeting for Spain , sorry for my English, bye.
I have a doubt, As per the information available on sites, it will require a minimum of four Mosfet(switching devices) to run single phase BLDC motor but how you did that with two MOSFETs without the feedback circuit. Plz Help me with this
Thanks @Awesome Tech !! 1. IRF540 is cheaper here. Which resistors should I use? Same? 2. Do you think could be risky to a PC/motherboard/power supply because posible broke/overheat/shortcut or it's safe? 3. How ca we vary the speed a bit to reduce speed/noise if required?
I have biuld this. But it not works as good as you saying in this vedio I try different mosfets.but it needed to rotate in order to commence spining.also its not enough powerfull
Hi wouild this work for a bigger brushless mottore and wouild this work for a dc battery back it wouilf be ran by a speed controler to limit current thanks
@@PhdHung I have tried to make with the 70L02H n-channel mosfet series smd, but the result is the fan only moves right then left ... does the mosfet not match ...
I have one which has only two connection points at the stator unlike yours which has three. I want to ask how to control that with your mentioned technique? Plz reply.
The working principle is similar to the ZVS circuit. When supplying power. Because there are differences in resistors - mosfet - coil. There will be a mosfet enabled first. It will "lock" the 2nd mosfet. But soon, the coil will appear an inductive current to turn off the mosfet and activate the other side. This repeats and creates a constantly changing magnetic field. The motor will work.

uhmm whats the frequency range?
so i can make a high frequency transformer with this circuit
Can you add a volume ( speed controller) to this circuit? If yes how?
In circuit diagram you mentioned 220 ohm and 100 ohm resisters but you use 470 ohm and 100 ohm resisters. Is it correct.
Nice idea your the only one made this tutorial on youtube it helps a lot😊😊

Just awesome and very useful for recycling fans with broken control boards
Very good project
Sir I liked your video and your teq thank you very very much.
very Good
thanks
Gracias por su información. Una sugerencia, cuando haga un dibujo o esquema por favor los números y letras que sean legibles.
Great sir, the only video 👍👍
Thank you for video I do will repair the fan
Sir best ❤ u. Pz. Ditermine simple 🎉🎉🎉
Wonderful video. Great way to run this fan. Sure I will give a try to such method.
Sir can i use bd 139 it works or not??? Or 6n 90c mosfet???? Which transister we use?
Excelente video, así debería haber en habla hispana, aprecio su trabajo
2 fans from trash fixed up an running in my battery charger, bravo bravo brother. Thanks.😉😉😉

Thanks, you give the schematic sir👍🙏🏻😁
Very nice information video thanks for this
Thanks for sharing the information!
Is it irf3205 mosfet or irf2205 mosfet? Which one is correct?

it is the zvs circuit
Do mosfets get hot?

So i try on small bldc 2.5" motor with 200 and 100 ohms. WORK WELL. Full speed. With 3.5" get mosfet hot so i quit. Using irf630fp both. From old tv
Hay đó bạn
cám ơn nha
Nice video bro please make Tesla coil with mosfet please please please
I have a lot of requests for building circuits. Wait for me.
Bueno si me encanta los inbentos k
Thank you so much my brother , what is the frequency obtained by this circuit please ?
Hi. Wonderful
My device work perfect but for start need to spin the fan manually
And for low speed is a noise
Anh ơi cái loại motor này nó quấn dây giống mấy cái quạt tản nhiệt 12v trong máy tính phải không? Cám ơn
là nó đấy. Brusless 2 pha
Tiện cho e hỏi là loại motor này có 2 cách quấn thì mình quấn 2 sợi song song thì quấn sao vậy anh ? Cám ơn
Verry nice brother.
Try something to fire stepper motors also
Like printer or hdd motors
oik ok
Can you tell me name of MOSFET and value of resistances?
100r 2x , 220r 2x, z44 mosfet 2x
@@MythHoor thnx
Very good
@@MythHoor thanks
It's well my friend, what is the frequency of the circuit please ?
6:42 so for 6 poles or 12 poles, simply measure the resistance from those 3 points to decide the center point?
I am not sure. :)
Love Idea
thanks bro
Very nice video,good job
Thanks
Why it will not work directly from positive and negative wire plugging in battery
if 2 mosfet and 4 resistance is enough to run these BLDC fan then what is need of the circuit board inside of the fan??
It needs control board to measure temperature, connect to CPU (fan speed measurement), control speed etc ...
@@PhdHung okk understand
Nice....sir....but open in hard and dead...fan
:))
can you show with hdd motor or cdrom motor which is very powerful.
ok bro, wait me
Nice,thanks-----!
Thanks.

Thanks
excellent
Thanks
Are useful for hd driver disk motor.
Good
Thanks bro
Very nice
I try it the motor just turn and reverse back don’t understand how you get yours to work and it a very very simple circuit
Vai ESC k leya kon SA register use keya
Very good project but how can we increase the speed???? Can it possible
unfortunately not possible
@@PhdHung it's Okey and thanks for your reply
If you eat loving person watch my channel and enjoy with your technical work 😘
I have biuld this.
But it not works as good as you saying in this vedio
I try different mosfets.but it needed to rotate in order to commence spining.also its not enough powerfull
I have also assembled the circuit but the fan needs to be given initial spin to start.
thank you .
Aws, I’ll try...
Super cool o.o :D
please use different colors for negative and pozitive wire, black and red .
Good Sir
Thanks for watching
Which current you using ac or dc
DC 12V
Not working
friend already saw your video more than once and I have a guideline the resectors are not changed in relation to the assembly and the diagram?
O
What type of register you used ???? How many Ohm
That was Awesome man, u have cool stuff their 👍
The best!
Thanks
NPN ?
I think it will work because it already acts a pulldown
it use ZVS driver
good afternoon congratulations if this cooler motor works with this circuit with mosfet, hd motor also works with this circuit
I am not sure, I will try and answer you.
Hi wouild this work for a bigger brushless mottore and wouild this work for a dc battery back it wouilf be ran by a speed controler to limit current thanks
Can I use npn transistor instead MOSFET
I think it can.
Resistor Kon sa lagaya he Bhai ye to Bata do
great job. thanks.
four stator coils, two coil connection only. no center tap
how to connect?
rewind into 2 coils
@@PhdHung opposite two coils are in series connection. hence four stator coils makes two sets of coil only

Thanks
very good
Sorry for disturb you again sir, please tell us IC number it seems IRF4205 as N FET at 4:18 in video
Must reply sir it will really helpful for us.
How many turn in every single coil
Yes, of course
How many turn those brushless coil that you rewinding
I just wonder how many turn those coil sir...
very smart
Very good idea dear brother 👍👍 1m like from me.
Thanks
So nice... did u change winding or it was original winding?
Gracias por la Información. El motor es de 110v o de 220v?
What is pros and cons of both, with control circuit and with MOSFET
Please make big bldc motor for air cooler lowest amp & high rpm🤘
Resistors G-S is 470 ohm.Resistor G-coil motor is 1kohm.ok?
yess
Sir, it is osome. Can i use normal transistors in the place of mosfets
What resisters and nfets would be required if we could fix an AC fan of 220 volts with this method.
No, this circuit is for 2-pole fans only
please mention the details of resistances and mosfets to enable me to attempt as shown in your video
Does this system apply to all types of DC 12V fans? By the way, can it be rotated right and left for the fan system ...
Use for all PC fans.
