Motor for QuadCopter

(1/2) > >>

vipulan12:
Hey, I am currently looking for motors useful for quad copters

-the motors needs to have high RPM, adequate torque and be extremely light weight
-the quad copter is expected to lift a camera

currently the weight of camera and other parts are unknown
I am planning to use my arduino uno for this project

any suggestions or advice would be helpful

Errr... Finding the total weight is not just a good idea - it's mandatory!

You can't find the needed motor/propellor combination without knowing how much weight it have to lift.

vipulan12:
so lets say i have the the weight,How would i calculate it,What formula would you use?

Obviously, the total available thrust will have to exceed the total weight, right? And you need some margin to allow some motors to be throttled back to make it turn / move.

A quick google search for "brushless DC motor propeller thrust" turns up quite a few resources such as http://adamone.rchomepage.com/guide5.htm

Of course, you have the old chicken and egg problem - you don't know how much it will weigh until you pick the motors and the batteries. But you don't know what motor / batteries to pick until you know the weight. Right?  So you guess. Pick a weight, see what motors that leads you to, check to see if you are close to your target weight, then guess again. After a few tries, you should get a workable answer.

what is the formula to calculate lift for a quadcopter?
