How to run HDD motor without using driver only by transformer 

not working

for sure yes , but it worked without using bridge, beside you will find motor so hot after using AC

@@creativelife4453 Is your transformer supply DC output? If not! There are 2 questions. 1. With 12v ac supply Hdd motor never run until once move motor manual. (I have tested many hdd motors) 2. And direct DC supply never run motor(untill driver circuit or using supply ic like 7805 etc. Or using capacitor 3300 mf or more (modulation) *Your video seems fake Or you may explain theoretical*

@@aftabraza92 The video does not seem to be fraudulent, because the AC current distributed to any 2 branches in the star motor connection (wire 1a2, or 2a3, or 1a3 and wire 0 is omitted) actually turns the motor. It is very inefficient and the design is Lama. I agree that it is necessary to turn the motor manually at the beginning, but it is possible that it has some magnetic error - it is possible that the magnetic ring of the rotor is cracked. It is best to direct the alternating current from the transformer to direct current (4 diodes and a smoothing capacitor) and use 3x MOSFETs, several resistors and diodes ...

220 volt for transformer, you can see it written on metal cover of transformer

Thanks

sure for pulsed wave

first i was surprised that Ac transformer can make this for stepper motor as we know need signal for current for each coil, second its Ac source not DC In case you like to sure be i can make another video show real current in and out and prove this vid real , not fake . im not here for making fake vids here in my channels,i share things that i can do only , i don't make professional videos or cutting video to make it fake . anyway i will make other video show Ac volt in and out .

thanks

how many terminals for motor, and do use 12 volt DC transformer

yes , you are right

I have had same to same HDD motor but it has no wires from outside {actually I am a kid from India ,Surat}I have a RU-vid channel also

@@nightshade2009 good you need to solder wires, why you turn off comments on your channel

I don't know how to turn on comments

Subscribe 'Niky darji', it has the video of my HDD motor it's my old channel

but at least worked

Může - Can - 3x Mosfet, 3x diode and 3x resistor. You can find a simple scheme on the Internet.

yes but motor get very hot so fast
