    Hello

    I am basically new to all this... ESC stuff..

    Thing is i have couple of old hdd's and dvd drive's motors lying around. I need to drive these motors for DIY projects.

    So i researched a bit on them and found out that i need some sort of ESC to drive these BLDC motors and Servo controller to control their speed.
    A friend told me to simply buy a 10A ESC + servo controller.

    But i am now hit a wall. You see i am stuck on how do i power the ESC? I don't have any LI PO battery. Can i power ESC using regular power supply that outputs max 12v 2 amps.

    Can anyone explain?
    I appreciate all the help..

    Thank you

    Get the spec/datasheet for the ESC/controller. That should tell you the supply requirements.

    If you rummage on ebay for hdd motor controller, you'll find you can buy a pcb for about 3 quid that controls small brushless motors, they have a pot to adjust speed from slow to 7200 rpm, I have a couple they work well.
    Driving a motor without feedback sensors is no easy task, unless your a skilled programmer.
