I don't have much experience with Electronics but I'm an engineer and programmer and have wanted to start playing about with some projects using a Raspberry Pi and/or Arduino.
One project I want to start involves very precise angular movements on motors. I'm looking at stepper motors but know very little (I'm an aerodynamic engineer so my skills don't translate lol). What I need is 3 motors, that can turn in increments of about 1 degree so I am looking at 1.8deg stepper motors with some micro stepping but the more steps the better. Two of the motors will turn very slowly, with the other having a max speed of about 1-2 revolutions per second.
The project isn't big and I have been looking at motors as small as possible (sub 45mm3 ideally)
My biggest issue is that ideally I need to know the angular position of the motors at any time even when turned of and on. I have looked at Absolute Radial Encoders and Potentiometers but wondered if anyone had any thoughts? Am I trying to do the impossible?
I would appreciate any help,
