Full Motion Antenna motors designing problem

AI Thread Summary
Designing a full motion antenna involves calculating the necessary parameters for two DC motors (elevation and azimuth) to effectively move a 1m parabolic antenna. Key considerations include determining power requirements, torque, and output voltage for the motors. The antenna will be used as a VSAT on a vehicle, necessitating a design that accommodates mobility. The designer has a background in satellite engineering and some mechanical knowledge, aiming for an accuracy of +/- 1 degree. The discussion seeks guidance on the theoretical aspects of motor design for this application.

Dear All

I want to design a Full motion Antenna. But I want to start from the scratch.

Suppose I have a 1m parabolic Antenna and I want to install two motors (Elevation and Azimuth)

The motors should be DC. And I want to know how to calculate all the parameters required to move the antenna. For example how much power it would require, how much torque, how many output volts.

Lets say the Antenna would be used as a VSAT installed on a vehicle.
Kindly help me in getting started.
Thanks and Best regards

What is your background? Have you had mechanical/physics classes in statics and dynamics? What kind of motors and motor controls have you worked with so far? What resolution and accuracy specs do you think you have for this project?
 
Thanks for your reply.

I am a satellite engineer basically but I do have some mechanical background. And this is my first time to work on motors. Initially I can keep a accuracy of about +/- 1 degrees.

I just want to know how can i theoretically design a motor for the required movement of the antenna.

Thanks and Best Regards

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
