I want to build an antenna rotator for a 1M dish. How do I calculate the required torque for the motor of the elevation axis?
Here's a sketch of the problem:
If the "bottom" of the dish is the pivot point, what would be the required torque to rotate the dish around this pivot point? Obviously the motor will have a series of reductions to reach the required torque and speed. The last stage a worm gear with a turn ratio enough to prevent rotation from the antenna weight when no power is being applied.
