In following your replies, I’m not actually sure what you are looking for in this thread. Do you seek examples of non-emotionally-framed aliens? Or just thoughts on how to execute such a species? Or is this more of a statement of your own goals?
If you want truly alien aliens, I‘d first play with a lifeform that was not evolved by natural selection. An example might be an AI created by some progenitor species. Such a lifeform is free to have an arbitrary divorce from what we consider basic mechanics of living (such as emotion).
As for naturally occurring creatures, there is only one known (or theorized) scientific method for making life forms, and it is evolution through natural selection. Anything that developed naturally, on Earth or elsewhere, is therefore pressured towards certain lowest-friction solutions to the problem of living. Some kind of central nervous system with the ability to react to the environment with an understanding of how that environment affects its own well being is pretty unavoidable. Maybe that is a lack of imagination on my part, but I have undertaken the thought experiment without much luck. Once you are processing input and applying it to your own self, emotion isn’t really a magical addition to the recipe. It is nothing more or less than signaling from your brain when things favor or harm you in certain ways, encouraging you to repeat or avoid or enter some particular necessary mindset. How those “emotions” manifest exactly, could vary, I’m sure, but it would never be difficult (I suspect) to relate them to human emotions. Thus, even given a creature that doesn’t experience any human emotions, we’d still be able to map their own reactions back to familiar reactions of our own, and we’d slap a label on it and call it a day. Point being, if you were writing about such a species, it still might not seem quite as alien as you are hoping, even if it isn’t feeling precisely any of the emotions we’d immediately call our own. Does that make any sense? To put it another way, our ability to anthropomorphize is likely to outmaneuver nature’s ability to create distinct non-human emotional states.
