I swear my Mother In-law has a few of these Motors in her mouth, Once she gets started, there is no stopping here :o/
LOL
Hahaha
🤣🤣🤣🤣🤣
😂
How not stop can you share me that's wiring ( 3 pins)
Connect these to a low voltage 3-phase power source. This makes it a AC synchronous motor.
and what is that low voltage please
@@jumcopper anywhere from 6 to 12 volts. ( or about 9 volts or so RMS per phase.)
I have a 9 volt DC transformer. Is there a way to make that work?
Can these motors be used to generate electricity?
Yes
Why it not start automatic?
Thanks.
Dont work 👎
👍🙏
You CAN use motors made as part of the frame - I have several. You simply need to very carefully cut the frame around the motor (ideally with a band-saw) making sure NOT to damage the flex connector that will almost always be present for such motors. Once cut it can be used like any removable motor.
By adding a capAcitor between ANY PAIR AND Supply the other two it will spin by itself associated with vibration my innovative friend
@Francisco E. Parulla same way a single phase induction motor needs a capacitor to start. And switching the legs connected to that capacitor will change the direction.
you are right
Starting capacitor like a washing machine motor but on a micro scale. 👍
A washing machine motor is a brushed universal motor. Not an induction motor.
@@simontay4851 never seen a washer with a universal motor, I've seen single phase ac, I've seen brushless motors, I've even seen a three phase induction, but I've never seen a universal motor on a washer.
1:48 "In this case we can't use the motor" I beg to differ. We can use the motor o-n-l-y in this case.
His 'this case' meening: the sitruation and not 'the frame'.
@@kjyhh its a joke
Lol!
Thanks, very interesting.
Single phase create oscillating magnetic field. You need minimum of 2 phase to have a self starting motor (for synchronous motors). Also, speed of motor will be fixed (synchronous motor + 50Hz).
You didn't give DC supply. Your supply was AC
Every Device who need DC power they definitely runs with Supply or Adapter so they use mini transformer as Supply. Transformers converts AC power to Dc as low as you need.
A start capacitor should work, you may need to play with some different values ranging from say ~20uF - 300uF and suitable AC voltage rating. Placing the capacitor between the floating phase wire and one of the other AC phase wires will result in a phase shift in the current and subsequent magnetic field shift in that winding. Resulting in a tendency for the rotor to favor to move in that direction and thus allowing the motor to start spinning up to near synchronous speed. Different the start capacitor capacitance will give different phase shift angles depending for a given winding impedance. This increased phase shift together with the increase is winding current due to the apparent change in the winding impedance due to the introduction of the capacitor impedance will result in better starting torque. Note though the starting torque will not be very high or as good as having a 3 phase VVVF driver. The added benefit of a PWM drive is good starting torque and variable speed in excess of that attainable at normal mains frequency.
I guess the 4-wire brushless motor has an internal star configuration wiring. So, by connecting the common pin to a DC voltage source and energising the other three pins in a correct sequence can make the motor run, much like a unipolar stepper motor. By using a decade counter with a signal generator, such as a 555 timer the motor's speed can be varied.
The reson why u must give a push is because the alternating current only flows to 1 of the coils. If it was hooked up to a driver the driver would fire the coils n,s,n,s - and so on deleting that push from the beginning and have much more power and efficiency
And I thought. Useless without a driver.
Basically yes... Kinda like the Tesla
Use a brushless controller from a model aircraft and it will self start and you can select the speed by injecting a pulse between 1 & 2 mS (simple 555 circuit)
ruclips.net/video/TeZXXDoEGuc/видео.html
Could you use caps to convert the transformer into multiphase one, and then energize all the coils to run the motor at higher efficiency?
AC???
Hmmm but on the drive sticker itself its this DC symbol with the dotted line and the non dotted line.
I've added a speed control using a sine frequency generator on my phone wgere you can adjust the frequency. I plugged my phone audio out into an amplifier which then, I connected to the motor. But after around 150 Hz, you start getting harmonic imbalances and the motor comes to a buzzing hault, because you are usung only one phase.
I did this also to my stepper motor
Can you do a video on Charging and discharging caps in series and parallel under different loads?
Let me think about it
0:56 that's the HDD for the XBOX original
Oh god...
I'm pretty sure they all were.
Can I just use an l298N motor driver to drive this motor?
actually motors that are a part of the frame are more usefull. if you tighten it with a vice near the shaft holding the bearing the thin aluminum cast will break and the rotor stator assembly come off in very compact form. after that you can pull out the shaft to rewind the motor if you want and in my case place 3 hall effect sensors. using this method i converted 20$ rc car into brushless rc car
Depending on the size of the magnet you could probably use a PC fan controller as long as it has PWM enabled. Not sure if this would work tho? Maybe three phase motor would work. Theres always three hall sensors in that case unless it uses current pulse to trigger the next phase instead of hall sensor? I wonder if it would run with just a pwm pulse square wave or does it need zero crossing? Gues ill find out. Im playing with one now.
Thanks for sharing now I know what I can do in my old harddisk
60Hz. You have no idea what you're talking about. You just stolen another one's idea.
It is 50Hz in some countries and 60Hz in others.
In fact brushless motors work with AC current that come from electronic cuirct and control of speed by different frequency. There for its work with AC currnt that come from transformer but its slow because the 50 or 60 hertz it's so low frequency for this motor
Should the supply be 12 VAC maximum? And I was wondering if these little motors are basically induction motor without magnet as a rotor but more like a squirrel cage rotor?
Another amazing video. Excellent explanation and original thoughts. That's what i like the most in your videos.
First request : Please never shut down your channel. It is one of the few gems here on RUclips.
Second request : Always keep your videos like this: simple!! And to the point. With pros and cons of the things discussed out.
I really really appreciate your work.
Keep it up!!

Tanya om, kenapa sambungan kabel ke motor tidak diperlihatkan ? Karena banyak video yang tricky, jangan-jangan dibelakang nya sudah diganti motor ?!?
Setelah disambung kabel, jangan hanya bagian muka yang diperlihatkan. Tunjukan bagian belakangnya untuk meyakinkan bahwa motor masih tetap aslinya . Terimakasih.
Salam semangat. Saya senang dengan video2 LS.
That means i only can give the motor AC current.
3:55 he Really Touched the Transformer 😂😮😅
If you want a more reliable motor you can just connect a capacitor up to it and put it on a different pair of ac line creating 2-phase ac instead of just one
Does it work with a 9volt transformer?
Great and informative video. Thanks for sharing.
Thank you for narrating your video. so many foreign videos don't.
Thanks You Sir!
You did it in KISS teaching principle.
can you turn those motors into generators?
Yes I have a video on that
do you have a link?
thank you
Would adding a capacitor like copying the idea of a usual single phase induction motor help to maybe allow self-starting? Also is it possible to do this even?
Yes.
60 HZ = 60 RMP? HDD MOTOR 5000-7800 RMP its bad driver
That's not how it works. First of all hz is per second and rpm is per minute. Second you have a number of poles inside the bldc that you need to divide the hz by. So basically if you have a 4 pole hdd motor, at 60hz you'll have 60hz*60rps/4p which makes 900 rpm
Very nice and useful information, thanks very much!
Un capacitor no podría funcionar para "evitar" darle el arranque manualmente?
Quay yếu lắm k đạt max công suất
ok thats cool but imma need a potentiometer cuz i want a 7200 rpm fan just to see if it works. then imma take a sas drive and make a blowymatron
Use 3 phase step down transformer
Use a capacitor whit one connected wire and the not connected wire and it will start on it's own!
Then you will have a fase shift do to use of the capacitor.
Very nice
Ese va andar como ventilador
This metod îs very good to test the motors
Hmmm so they need 12v AC, not DC right? my hdd just broke and I'm playing with the motor XD
Thank you from 2022...😄
Saudações LS Ludic Science. Saudações a todos. Interessante. Deve ser possível fazer esse motor girar a mais de 30000 RPM. Tudo de bom.
Motor DC input voltage AC very fun.
It is not dc motor you can make it to do using controller original or make it you probably don't know nothing about ac dc current any thing you can make it work using electromagnetic induction and pulse
very helpful, thanks
*Super Cool* 👍👍👍
how about a wave generator??

If it runs on only 50HZ frequency, that means it have only 50 rotations/second
Nice videos👍👍👍💖
Very COoL... Beautiful little motors! Curious what the wattage draw is spinning and "not spinning". Thank you for the video.
can you please make a video on how to run hdd with laptop charger adapter
Thanks, good vid as usual, really informative. Could you show how to set up a simple driver circuit/s to drive these motors. TF sharing.

Now I know thanks for sharing
What is the point or possible usage if you have to give initial run? The scratch your back maybe?
I don't have any esc, transister ,transformer nothing can I start my hard drive motor of 4 terminal
Its running, sans one winding. Which is why it won't self-start
be nice if there was a way to reuse the controller board, perhaps in a maintenance mode. ah well. lots of nice parts in these
Please tell me this mortor oparating voltage and amp .but not working my 4 pin hard drive mortor .
Got a link to the transformers please? Cheers bud ;)
Chuck a big ass capacitor across to the 3rd lead, should work like a single phase induction motor (it's how combi boiler motors work)
انا لا احب المال
Motor heats very fast
Nice video .. I just loved the unscrew's sound 😁
Eres Manuel?
Great video re-use part and misc components is the future of humanity
thanks!
Those are the 3 kinds of hard drives that I've only seen in an original xbox
it still requires that part so either way you still have to buy something or find it inside something....the same as finding a small speed controller and parts inside something but on ebay you can by the parts needed to work for like only 3 dollars for small motor like that.
Does anyone know what companies have removable motors in their hard drives?
I have this model 1:49 , no way to take off the metal disk, it's like there's a hidden screen
Thanks for the experiment. Why not try using a HV starting capacitor to get it started? Maybe use a microwave oven capacitor.
Joseph Nicholas maybe you could get it started with a 20v high capacity cap and a rectifier, but considering the poor reliability and torque you get I guess it's much easier to buy a dedicated chip.
Valuable video nonetheless. Could turn out useful in a pinch.
Why the HV capacitor? the motor is quite much made for 12V and a capacitor wouldn't help you get it up to speed, it's a synchronous motor and not asyncronous induction motor where you can have it slow-starting.
The AC would need to track the motor up to speed for the start to work. Or it must start on some few cycles or be spinning the right speed.
Thanks for this video i am going to make video on this
a car engine is only 12% efficient using 100% power.
a cap between the freewire and + or - wire can run the motor without touching it forward and backwards if you change + or -
thanks for sharing your videos 😇😇
But faible ampir !!!! Not application
Can you in any way make the speed adjustable? And is I put a 12” platter on to the bearing can I get to it speed at 33 1/2 rpm ?
i don't get it ... why is other sites using a 30a ESC brushless motor speed controller if all you did was hook up 12 volts to two of the terminals? i only know enough about electronics to get my feet wet so I'm guessing I'm missing something here ...
because by this mechanism you will not gain speed.. not gain torque..

How does the hard drive start the motor off? Can't you use that system to get the motor going without using your fingers?
The work is very incomplete because it does not contain our view of the place of welding the three wires to see you and learn from you
Yeah that's neat, but used as such the motors are pretty useless.
What is a 12 volt transformer?
It is best to simply say what are you supplying to the motor with exactly. 12 V AC, 12 V DC or...… ?
It would provide 12v ac at 60hz in the US
@@hyperion112 I can't even begin to describe how I feel about choice of words used, especially in science where word accuracy is more critical than any other area.
Here for instance when I hear the word transformer, it instantly and subconsciously to me it implies going high, going up. To transform. It is how it is used in everyday language. Imagine telling that something has transformed. That person has definitely experience some sort of transformation. he seems much more disciplined etc. But in science it is an outrage. And I have no desire to bore you with writing a long a narrative. Just one more for the road. Particle spin, spin up, spin down. Big baloney bullshit.
Just use an esc
The AC somehow acts like the pulse?
Those HDDs could be sold as tech antiques (for a lot of money) many decades later (on eBay). 🤔😉

well done . Next tutorial .... how to connect an ESC/DRIVER
Well.. the basics would be: find the 3 terminals with equal resistance between them, and connect the ESC/controller output to those!
