I added support for OBJ groups a few years ago.  You can load just a group and rotate it for example.  Check the docs for your modeling app on how to make and export groups into .obj.

The multimodel object allows for a range of models to be loaded and then called using the right inlet.  The old Quake animations used a series of models for the animations loaded into display lists.

Hi,

Im interested in adding 3D models with integrated animations.

An example: I know is possible loading any .obj model, for example a
helicopter, but if i animate the propellers of the helicopter in Wafefront,
could i take not only the helicopter but even the animated propellers to GEM
(OpenGL)?
