How to make brushless motor controller - Brushless BLDC Motors 12V - 24V

How to making a controller brusless motor with 3 mosfets is very simple
How to make ESC using 3 mosfet
I have found the solution to adjust the speed:
I tested on bldc disk :
Thanks everyone!

just a brake down for understanding. hot to coils. mosfets are on off switches. the caps turn the mosfets on briefly. the resistors' count controls the timing. so for speed control you need to either adjust the time with viable resistors or control the watts on the hot.

Đã chế thử theo cách này, motor chạy max luôn, dùng 3205... đều ok. Lắp thêm con d718 (hoặc 5200, mosfet ...) để chỉnh điện áp. thấy chạy cả buổi mosfet ko nóng gì cả. Thanks đã chia sẻ

This is brilliant! Thank you!
I’ve got a really simple little 555 PWM circuit that I use for testing brushed dc motors. This is the perfect companion circuit I’ve been looking for to quickly test BLDC motors I’ve scavenged from old appliance.
So many overly complex circuits on the internet that don’t work. It’s so good to find something simple and effective.

Awesome video! I love hearing the animals in the background, you should do a video of them 😀

I subscribe to your channel.Because, I have been looking for a video like this for over a year. No one has put up a video about this so easily.

Awesome video, found a bunch of Fairchild MOSFETs (AK50BA FDU 8796) and diodes on an old motherboard and presto! Finally a BLDC controller that we can make from scratch, everyone else's videos require a bloody speed controller or & pwm generator of some form or another! Thanks!

PERFECT.exactly what I need. I have a dead 12v dc submersible pump dead due to a crushed controller. The perfect solution since there is no spare around!
THANKS

Congrats! You were featured by @GreatScott!

thanks bro, its work for me, and very simple driver. can't wait for delta conection with out hall sensor.

Bu devrede hız kontrolü yok. Sadece Enerji verildiği an çalışıyor enerji kesildiğinde ise motor duruyor. Bu elektrik motorunu verimli çalıştırmak için hız kontrolünede ihtiyaçı var. Emeğine teşekkür ederim.

Fantastic. So simple. Thank you for sharing.

TERMINOLOGY TECHNOLOGY CLEAN SIMPLE WITHOUT WORDS.. THANQ YOU...

Excellent, but only applicable for "star" connections. In addition, it is basically an oscillator, so it will not work on different motors of a similar type unless the parameters of the components change.

Hola muy simple y efectivo, pregunto : se puede aplicar a un motor paso a paso ?

[aportandolealplaneta]

Realmente maravilloso gracias por su infinita sabiduría bendiciones

Brilliant and great.
What about a 12 - 120VDC input with 80A - 120A for sensorless BLDC.
Can you design such high V/A circuit?

Hello, Very good summary of brushless motor control. In my case, I am looking for a controller for brushless motor. The motor operates at 12 to 14v and produces 850w of power. This is to be able to control the motorized fan of my vehicle which no longer works because there is a CAN network problem. I used the controller in your video but it didn't work for long (burnt out) because it was too light for the power of my motor. Do you know of a commercial controller that can accept the power of my motor?

It is posible to run bldc 126v sir?? With upgrade the mosfet sir??
