Descripción de motor from ancient hard drive:

This AC motor comes from a really ancient hard drive. I don't know the details of this hard drive as there were several parts missing. What I do know is that the platters were somewhere around 5-7 inches in diameter and the entire drive must have weighed in at about 30 pounds! In this video I've mounted a fan impeller to the motor to demonstrate how much power it has. That's a lot of power for a hard drive! In case you're wondering where I got this, I got it amongst the boxes of "junk" in one of the labs at NAIT. It's amazing how much old stuff you can find there.
