How to determine what electric motor to use. Need guidance please.

  1. Oct 31, 2014 #1
    Hello all!

    I'm an engineering student who is taking part in a group project to design and build a UAV to carry out surveillance in Greenland. Now my specific task is to sort out our means of propulsion and materials. The problem is up to now I have only learnt about petrol propulsion systems in terms of maths.

    We are aiming to use an electric motor due to several limitations such as cost and weight. I was therefore wondering if someone could link me to some material which explains the mathematics that need to be attempted in order to work out for example:-

    The range equation for an electric motor.
    Thrust that can be provided.
    How to tell whether or not a battery will be compatible with a certain electric motor. Etc...

    What makes you think electric motors are cheaper and lighter than petrol engines?
