And yes: it is very possible that these motors are inside the Technic Motors too (although a bit modified...)
Should I model it too (Dimensions: Diameter 23,5mm, flat part 18,5mm, length 27,8mm, driving shaft 2mm)?
Don't get too far out into the weeds detailing the internals for electrical parts. Simple placeholders, if anything at all, are sufficient.
