hi every one
i m need to use hard disk spindle motor for my proj bcos it gives constant high rpm like 5400 or 7200rpm. i have some dumb harddisk. pls tell me how to run them. is it possible to use normal power transisotr to drive those motors. samsung harddisk motor comes with 4 wires and seagate harddisk motor comes with 3 wires. if i give a voltage to any of those pin the motor just jerks and stops.

Presumably they are DC brushless motors?, and the electronics required to make them work will be on the PCB. I've just taken a number of Maxtor drives to pieces, and they have four surface-mount power transistors feeding the motor windings.
