What is this type of sci-fi mechanical device called?

Wait 5 sec.

I'm trying to identify the terminology used for this type of sci-fi mechanical device. It appears to have a glowing cyan core surrounded by a heavy metallic housing with concentric rings and mechanical details. Is there a general term for this kind of object in sci-fi design or 3D modeling? I'm looking for keywords I can use to find similar 3D assets and references. Thanks! https://preview.redd.it/u1kk97cn0avh1.jpg?width=931&format=pjpg&auto=webp&s=5d4503ff8f2af0dec73d48fc3d03e52b3f61a7de   submitted by   /u/Low_Garlic_8668 [link]   [comments]
