Which motor is used in satellite to rotates solar panel,sensor,dish antenna etc
I suggest to take apart a satellite dish and see what the manufacturer used.
In the general case, the construction of the dish will determine the torque required, and hence the choice of motor.
How to change satellite-dish antenna with motor in space sky how it move in rotation to send and receive signal from earth
We merged your two threads since they have very similar questions and moved them to a more appropriate sub-forum for general discussion about motors. We do not have any particular insight into what motors are used in satellites, but if you are curious how a satellite dish you own works, Jim’s suggestion of taking it apart seems like a good way to find out.
