Need schematics for electronic speed controler for a 3 phase hard drive (HDD) motor.

Hello. I have a problem. I've bought an old HDD for fun, if I can say so, it works, but I want to use the 3 phase motor for some applications, out of the HDD enclosure, so the question is how to start the motor?...I mean, I know that I need an electronic board to do that, so where I can find some schematics?...P.S. Don't ask me the brand name of HDD, cuz I don't know! Thnx and sorry for my bad english, I'm from Romania ;)
