How to get a spindle motor from a hard drive working?

[Jugernot]

I took apart a nonfunctional hard drive today and stripped it of it's parts. Mostly the platters, magnet, and spindle motor. Anyone know the scematics or a little knowledge of spindle motors? I hooked up both a 1.5v and 9v battery to this bad boy all I can get it to do is twitch one or another.

Any ideas? Here is a scan I took of it:

btw, the part number is DLH-337A made by Nidec as far as I can tell.

btw: I looked on their site and could find nothing.

Thanks guys!

HD motors don't spin on their own, they move in discrete steps. That's why you get the jerking.

Its not a DC motor. Its a pulse motor and you need a motor driver for it.

Since it has 4 wires, it is likely to be a bipolar stepper moter which will require some control hardware. Unless you're really serious about it, this will probably be too difficult to get working.

Wow, I keep telling myself to try that and now I know not to waste my time.

yeah it's an extremely uneventful component, nothing exceptional.
