HDD motor driver

[TheOriginalEviltech]

it's funnu how everyone can spin the hdd motors at low speeds, but when it comes to higher speeds the motor starts rocking and rolling...

[TheBypasser]

Well, in fact this one is doomed to fail. Why? Well, first of all a running '1' is not an option for an AC motor as you will get a 2/3 DC component which will ruin your switches and/or motor. A BLDC needs symmetry in bridge signals, also the high-Z state and PWM unless you want it to run as a stepper motor (needs BEMF feedback in order for the PWM to self-adjust for the torque and load) - the drive should look not like 100-010-001, but like 1Z0-10Z-Z01-0Z1-01Z-Z10.

**PLEASE REPLY** Hi.can it run at full speed like in original driver from hdd?? or is it's speed much or less thatn original one? Thanks

[MYSTERdima]

вот мы русские что за народ сломался сд-ром или винт. и начинаем какой то хренью страдать, а все ух ты она все таки крутиться, просто не могу понять куда их применить че крутить?...может кто подскажет?

[Dimm168pin]

@MYSTERdima .. собрал схему на TDA 5140A, но по недосыпу ее сжег тупо перепутав полярность на питании, забыл диод втулить, так что попробую это собрать т.к микруха не дешевая ни разу и регулировки нет. а тут есть. ну это оффтоп. а применяю такое в стабилизации изображения во время фото-видео съемки с 5D Mark2, первые тесты показали себя очень хорошо. от тряски достаточно одного блина на примерно 5000 оборотах, от 12 вольт около 8-9 тысяч набиралось.

[tyreza79]

please i beg you to put some kind of video fast motion tutorial on how to build the driver please! if you can do so

ill be so gratefullll !!!!!!!!

i have many dam engines but they just dont want to work, it seems they need some -+ alternator to them plus a gradual voltage feed or something,

please show us a tutorial on how to buid the driver,

[LBCFCSS]

You should try putting these onto roller blades/skates and seeing if it works.

[TheAstro30]

@LBCFCSS wouldnt be enough torque

[DRAGOONSHADOW23]

I hope the final version because I need this driver to control engines that I have thanks for your attention

[Hvdavi]

How many rpm u can get

[waqasgroups]

can you plz tell me how you can open or out the hard disk motor there is no nuts screw how can i take out the motor safely ?

[vspriyan]

The simplest among all circuits to drive a hard drive motor. Though the control, speed, stability may not be precise with this simple circuit, it can be used for simple appications. Great work !!

[ThePauloh9]

Legal se começace a voar kkkkkkkkkk

[FlorinCsAk47]

don't fly ?:)

[pvarelas]

Great work dude! Thanks for sharing your circuit! I was thinking of playing aroud with some HDD motors I have laying around and I had no clue of how to drive them...

[lishtek]

hello, excuse my English but I want to know how often operates at a medium speed and as you know the order of the motor cables, thank you very much for the schematic and the video

[TheBane22]

Faster Pussycat Faster :D

[valiza123]

my hdd motor has 4 wires. Does yours only have 3? With 4 you can just use a uln2003 to drive it (to replace the triple half H bridges).

I made that driver with a uC (12f675 and TIP122 and TIP127 which work a bit better then those tiny things) but for a brushless cd-rom motor.

[2DAREPUBLICAMEXICANA]

can you change the rotation? Can you make it spin to the right?

[hameeds01]

holy crap no feedback ?? increase the clock pulses & then see can it run again ?

[coldlogic1]

dont you mean virbrator haha

[spoulakkkk]

Gracias por poner un enlace para ver el esquema!

[JirayaRonin]

Hi, thanks for the circuit diagram, how can find the resistence value for the new transistor???

[chopinsmith]

thanks for the schematic -- could be useful as a turntable motor...

[lazaridisgeo]

your schematic sucks

[pikachuthesquirtle]

make a fan... would really cool u down on a hot day. :D

[manoftnuva]

where is the equilibrium? ))

[extremisto47]

Can i use an L293DNE with this motor??

[dyzio121193]

do yo speak englisch? sory J am polisch

[k323r]

dont need stepper motor to do that. a dc motor would do fine lollol

[rickreed123]

Did the transistors burn out at the end of the video? I ordered both some BC337/327 and some BD237/238 transistors, but it looks like from what you said, that the 337/327 can't handle the current. Is there too much back EMF? Thanks for the video and circuit diagram.

[GeeksRus95]

it would spin faster with two even blades

by reducing vibration

[JS106351]

I like it! Nice and simple to make compared to some other BLDC circuits out there.

[dukemcgee]

so what is this and what does it do???

[codyxcaution]

Proof of concept videos demonstrate that some things can be done.

And usually whats in the videos are hardly ever ideal.

Dumbass.

[dukemcgee]

no imeant the hdd driver what is it and what does it do. and fuck you asshole

[andben]

im going to kill you pretty soon

[TheAstro30]

@codyxcaution How is he a dumb ass? It's a PWM (Pulse-width modulation) oscillator, the 555 timer, connected to a 4017 decade counter with 3 push pull outputs to form a driver and power driver output (the decade counter im assuming is to switch one of the pairs of outputs on and off to form a crude hall-effect) ... how does that make him a dumbass?

[razorflown2]

"Who is your daddy, and what does he do?" lol

[cristian3131]

I followed your schematic exactly, but I have some questions: what value does the resistors have, does the wiring of the motor count (and if it does, what is what) and did you used 12 volts, because my microcontrollers get really hot even with 3 volts. Immagine what would happen when using 12 !

[cristian3131]

What is that 4017? Doesn't it have some letters before? I found something with 14 pins like in your diagram, but the functions aren't the same. Exactly what did you use?

[zledhu]

4017 / 74HC4017 / CD4017BC

[cristian3131]

Those have 16 pins. Does that work too?

[zledhu]

Yes.

[dangthanhlinh]

Hi. have a nice day. I like this project. I use Lm555 general pulse. 4017 is counter. I don't known dirve motor part. I try use 3 trasisitor B-out of 4017, E- GND. But It don't run.

You help me about it

thank

[cristian3131]

I am an electronics fan too, so I am going to try it. Thanks for showing this. Just a question: can that spin fast......very fast (like in the hard drive)?

[Micah461]

What was the value of the J1 pot?

[zledhu]

i used 500k, minimum 100k

[TheGeek1028]

I wonder what would happen if you did that with a 52 x CD spindle.

[kitsunegari21]

Please where can i find the schematic ?

[profineger]

Hast du einen schaltplan

[hacherul]

pls pls a schematic for this?

[JrockerForLife]

Make a few chopper blades for it and crank it up It may fly

[belgvr]

hahaha i did it... i put a razor blade on my hard drive's motor :D

works great ;)

[poweruser69]

can you post a schematic for what you just did?

[coilgunman222]

looks like the 555 generates a pulse train that increments the 4017 divide by ten counter, in turn driving the 6 transistors to turn the stepper motor.

[dangthanhlinh]

I don't schematic 6 transistors to turn hard motor disk. You can post for me

thank
