Idea for a project from a HDD Motor? Answered

I just salvaged the motor from a hard drive, I can estimate it spins at 3000-6000 RPM
Does anyone have an idea of something I can make with it?

While I like the Cotton Candy machine hack.

I think you would enjoy the levitating NIB permanent magnet. Tape a flat nib magnet to a flexible but sideways stiff flat cardboard or fish-paper strip positioning the magnet above the outside end of the spinning disk to see the magnet repulse itself by induced eddy currents in the rotating disk.

Hi,

By NIB, Do you mean neodymium magnet? Is it the same thing?

I just searched for an Instructable "DIY Cotton Candy Machine" and they look realy cool, I could be able to make one.

But, As Downunder35m says: I need a controller to be able to power it, Any suggestions?

When you estimated the motor speed, I had to assume your motor is running. Don't tell me the original HDD driver is now unavailable.

Can not begin to infer how complicated the adapting process of adding a controller to an HDD motor is (for me) maybe Downunder can offer assistance in making the connection.

And Yes, NIB means neodymium magnet

Don't say that, the older ones are actually quite powerful.
I converted a 7200rpm model with a dirt simple controller chip included to work on a gearbox.
Decided for this motor as I could use the HDD casing after cutting as the lid for the gearbox and mainly because the speed was regulated with a simple voltage signal instead of the usual PWM.
You have to fix the spit roast somehow, or what do you think? LOL

If you have a suitable controller for it....
