How can I make a hard-drive motor spin with wireless power supply?

[danthorpe2002]

Just found an old hard-drive and messed about stripping it down to its bare minimum, it's currently on my lap with just the curcuit board that controls the spindle, the actual spindle and the two discs.

If I plug a molex connector in then it will continuously at its idle speed.

My Question

If I want to somehow power this hard-drive to make continuously spin wirelessly how could I do this?

I was considering maybe a laptop battery of some sort?

any 12v battery would do it, although 5v might be required too.

 

[danthorpe2002]

Also, if I were too use a laptop hard-drive, would that be more compatible with a laptop style battery?

Wireless power eh.....

 

[danthorpe2002]

Yeh I'm not talking like a new invention of technology, when I say wireless power I mean like any sort of battery/ laptop battery/ car battery ... etc

spam? I'm currently in the loft looking for a 12v power source ...

The drive controller will also require +5v.

What exactly are you trying to achieve?

should be possible with the right battery

a laptop drive will run from USB

The worlds most geeky canapés platter.

Dont go with spam, it doesnt provide enough juice needed to power to the drive.

Go with bacon or a top side of beef.

I don't know if any of you ever watched robot wars? But there was a robot on it called hypno disc, basically a spinning disc with some rc servers etc in the back end.

If I could get this disc to spin without needing to be plugged in then I could build a mini replica!

... The things I do in my free time

Ok, that helps. Bear in mind that it's a stepper motor and therefore you can't just plug 12v into the motor and expect it to spin. You need to make an oscillator, a 555 based one will probably be easiest. The 555 will also require a 5V powerline to function.

 

[danthorpe2002]

Okay thanks, would it be simpler if I was too use a laptop hard-drive? Surely then it could just link straight to the laptop battery?

Thread title fails to delivery. I thought for a moment I had a legitimate reason to recommend this guide.

 

[Burnsy2023]

Assuming the battery had a 5V line, yes that would be simpler.

That link seems to be in a foreign language that neither I nor Google can translate.

Try again but this time read it using Schwarzenegger's voice, it works purfectly.

IF the laptop battery is 12V, and you need 5 V also, why not additionally use 4x 1.3v AA/AAA/AAAA ( depending on what capacity you want) rechargeable batteries in a series, would make 5.2 volt ?

I would suggest this. Using a laptop battery seems silly especially as you also need to recharge it which isn't trivial.

LMAO cracking

I laughed when it stuck to the floor

I am sure platter motors are 3 phase brushless motors.
