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.
