## How to calculate Torque for motor?

Hi,
I am doing a self-balancing skateboard. It uses two 24v motor to move two wheels.
I need to know if my motor will be able to move the wheels.

Given that,
wheel of 5.66 inches.
The total weight of the skateboard = 13kg.
Assume human mass = 80kg.
Total weight with human mass = 93kg.

How to know the torque to move each wheel?

Thanks!

 Recognitions: Homework Help Science Advisor Can you provide a sketch of the setup? Something similar to a segway? Where do you expect torque? If I understand your setup correctly, it depends on the maximal imbalance you get. In any way, you can estimate the order of magnitude (but not a precise value) with (wheel radius)*(mass)*(gravitational acceleration).
 Almost similar to segway only that this project uses hand controller. I don't have sketch of the setup. But if you look at this videohttp://www.youtube.com/watch?v=engi16bLJe0 , I think you can see the setup of the motor to the wheel. I only need to know how much torque is needed for the motor to move the wheel.
