I am currently working on a design for an Alt-Az telescope mount that utilises large (12"ish) axial flux motor (home made) with 18 coils (24 magnets) and a high precision encoder with sub arc-second solution. Obviously the primary function is to move the scope at a slow rate to compensate for the Earth’s rotation which is 1 rev per day (of course). The scope itself with all the cameras etc mounted weighs around 20kg. so a fair amount of torque is needed…especially to accelerate it and move it to a new target. I think somewhere in the order of 10N/m would be sufficient and I believe a motor that size could easily provide that at 24V and maybe a handful of amps.
My question … Is the ODRIVE suitable for this? I am a Python programmer by trade and therefore this is a very attractive solution for that reason. Would the current firmware already do this slow, precise movement - or would I need to work on that too? Lastly would the encoder input work with something like the Renishaw ring encoders?
