The Mosfet terminal D (middle one) and the screw hole metal are the same connecting conductor, it is important to show how isolation is done between the screw and the body of the heatsink. Otherwise all D terminals will be shorted.
This circuit simply isn't compatible with a delta configuration. A delta configuration requires current to flow through 2 coils, and this only does one, and to the common central point. You'd need 6 transistors and a microcontroller to control that - you've just made an actual ESC that you can control!
This is very impressive! I want to be able to do a scaled up version of this, for say a 5kw BLDC, to work for my boat conversion. I don't really know the 2nd thing about this stuff. Anyone willing to share their wealth of knowledge? I intend to use ebike-type parts but obviously throttle grip speed controller is t gonna cut it for a boat. A foot pedal could work, but is also not ideal. Any ideas?
Thnx brother it's great job but i have question this bldc is for 4 wire connection witch named start connection please can you make tutorial to bldc for 3 wire who named delta connection... Thanks a lot of i like your videos 😉
Nice video! One question: how do I make it stop? I've been looking to implement on/off burron to the slide potentiometer to use it as 0-100% motor driver and still need help
Excellent informative video my friend! Subbed and the bell on for future videos! I know you are probably very busy, but would you know how to control a larger DC motor out of a treadmill? Someone gave me the motors but they didn't save the control panels. Thank you!
What kind of motor is it? Brushed or brushless? If it has 2 wires, it's probably brushed. If it has 3 wires then it's probably brushless. If brushed, you can use single switch PWM even without filters. Just remember to put freewheeling diode. Brushed motor control modules are also available for sale. If it's BLDC, you are better off buying a BLDC controller rather than trying to build one (if purpose is learning, surely try building one).
@@matejgamingandotherstuff6484 he is using a special insulation washer, it keeps the metal screw from touching the fet metal tab, its hard to see in the video, but its there, these are very common in power supplies.
Hi Sir author Can u please anwer if mosfets IRF540 can be used instead of 3205? Also, the diagram in the end of the video is covered by pictures of next videos. Can you please put the diafram in a file and share? I will try to software simulate this circuit to check other parameters and help to improve it Thanks a lot for your effort and great work Best regards
thanks for your effort, I did everything but the potentiometer doesn't affect the speed!.......and if I have a motor with three wires only how I could connect it?
Why does this work, and how did you know it would, before building it? What causes the commutation? Does each section sense the electrical behavior of the next/previous driver/coil?
Like you for the diagram! There is no 4.7 kOhm resistor on the diagram, but there is one in the video. Why ? I repeated it exactly from the video - it works, but the motor itself does not start - you need to push it. I supply 9 volts from a laboratory source. Why not 12 volt power?
URGENT!!! I am looking for an audio pre-amplifier capable of 300\400 times gain. There are several diagrams in the N.E. manual with explanations, and it can be nerve-wracking to stand there with formulas to be able to find the ideal Rx value ..... . The LM358 IC is great but I would like to know what is it capable of doing? What max results can be obtained? In short a noise or a voice at a certain distance .... . How to get it as close as possible and then run it through an 'AB' type amplifier. But what wattage is needed ....... ? Thank you very much.
@@Fernybeme Yes surely it does but it does not bring it back to zero RPM post starting unless disconnected from power source, which actually should happen as there is a variable resistor or a potentiometer, when in closed position it should cut power to moter even if it's connected to power source, this is my concern dear friend 😂😂🙏🏻🙏🏻
@@Yaman-D-Chhaya ah, i see. Well you should be able to by changing the value of the potentiometer. He is currently using a 100kΩ potentiometer in series with what looks like a 4.7kΩ resistor to ground. I believe if you swap it to 200kΩ or 300kΩ it should bring it to zero. If not you can probably use a voltage devider instead. The will change the input from a resistance based speed control to a voltage based one.
Very cool! Maybe I'm wrong, but it seems that to get more Motor speed you are turning the Potentiometer knob to the opposite (left) side? Another thing, is it not possible to stop the Engine completely? Thanks for sharing.
the schematic in the circuit with the one in the video is not the same. it turned out that the diode was reversed and I followed the path in the video instead dropping the adapter and the hdd didn't work.

The video at 5:49 suggests a star configuration for the motor coils. However, delta configurations are also common.
This circuit simply isn't compatible with a delta configuration. A delta configuration requires current to flow through 2 coils, and this only does one, and to the common central point.
You'd need 6 transistors and a microcontroller to control that - you've just made an actual ESC that you can control!
You somehow made the video, you made the circuit money, that's how you made it ..

You should use plastic screws with your insulations
There is white insulation washers that make it not short, otherwise it would not work.
@@Ozzy3333333 but he used metal screws which could touch the heatsink from inside the hole

You just need to make sure the source drain and gate match on both transistors and you should be fine.
@@Fernybeme Hi, thanks for your reply. I have tested with both IRFZ44 and IRF540 and they bothe turn the motor at a voltage higher than 5V. I used 8V

Good job please can give the circuit diagram of the of the system
👏👏👏👏👏👍👍👍🔥🔥🔥
thanks for your effort, I did everything but the potentiometer doesn't affect the speed!.......and if I have a motor with three wires only how I could connect it?
Can you make the motor go forward and backward? And if you can do it; try to slow down the motor so we can see what direction is turning.
Has uno para el de 3 pines? Ya compre todo los componentes para armar el mio
3:08 I guess you can't replace the potentiometer with JR servo wire connector to stick it into the reciever and have working RC ESC?
Why does this work, and how did you know it would, before building it? What causes the commutation? Does each section sense the electrical behavior of the next/previous driver/coil?
thank you for the video. How can I determine the appropriately sized components to use for an approximately 2000 watt brushless motor?
You do not want to use this for a 2KW motor,why, it don't have good control, and a 3hp motor you want control, at least I hope so.
What is the function of the diodes installed from the gate to the drain?
excellent 👌 what RPM can speed?

explain where the impulses come from? If there is no generator?
Sorry, I figured out the circuit, it's a 3-phase multivibrator
But there are no capacitors! multivibrators need capacitors for reliable operation.

Wow thanks really helpful, please what's the rpm of the motor at 9v. Thanks in advance.
Simply awesome build loved it, just a question can this ESC start the moter from 0 RPM?? 👍🏻👍🏻 Superb video
It does in the video.

How to use this circuit in three wire hdd ?
Good job!!!. It would be interesting to achieve a minimum speed of 0 rpm, what would have to be modified?
Remove the power and you can get zero speed.
@@assassinlexx1993 that makes no sense.
@@luiscolmenares3454
Simply that no power means zero rpm . Now if it above zero then maybe.
@@assassinlexx1993 I repeat It does not make sense, what if you need 10 rpm and then accelerate it to the maximum?

some HDDs are 3 phase instead of 4 phase, how should its connection be thanks
How many amps can this circuit handle?
Thanks Any easy circuit for Delta connection motor plz share thanks.
Great job!, 9v how much amp required ?
0.5A -1A. sir
Is this considered 4 phase controller?
what dynamo is that? Thank you in advance
Can you use this one at three face brushless motor wire
U, V, W van a los mosfet pero si todos los tornillos están conectados al disipador están todos unidos? Lleva algún separador aislante en el tornillo?
are isolated with plastic rings
Can I use stepper motor instead of HD motor?
Nếu video có máy đo rpm để show min và max speed thì hay nữa bạn ah
Cảm ơn bạn đã xem video và góp ý.
Can we use 12v? And another question is the power supply is DC or AC because I've seen people are using AC to let it spin without ESC
We can use 12v. is the DC power supply. This circuit can be used for big motors: ruclips.net/video/se-RxeFEncY/видео.html
