I have a Stab 90 hh motor, and was wondering if someone might be able to explain the actual operation of the inner workings.
It intrigues me that a 90 dollar motor with just one input to receive information and power, can precisely position itself to positions just degrees apart.
Obviously, the motor has an encoder, but there are other questions which I wonder about:
1.) What sort of control signals are being sent to position the motor?
2.) How is the positioning data sent by the receiver to the motor positioner? Is
it delivered by some sort of RF signal?
3.) Is the motor just a "dumb" device getting complex commands from the receiver, or is it processing and acting on a simple input (like the the longitude of the satellite)? In other words, which part (receiver or motor) is doing most the thinking?
4) What sort of signal does the receiver get back from the motor when the positioning action is completed? Is it just a go/no go signal, or is it an actual
encoded position?
Not really important questions....I was just wondering.
Thanks in advance for any replies.
