no influence
But I would extrude the inner cylinder through the whole domain (along your revolution axis)

Check display of velocity contour and pressure --> are they in agreement with your expectations?
Check also mass conservation (report/ mass-flow)

your picture is quite small...
As far as I saw, you can draw a circle (cylinder-surface in 3d) surrounding your impeller.
You can also attach your geometry (*.dbs) if you want

if you cannot create a circle-split, then yes you will have to handle with dynamic mesh.
Can you quick post a sketch of your rotor-stator?

no.
The split should be a circle.
For undestanding, try to imagine a split like a star. If you rotate your star with 10°, you cannot superpose rotor and stator regions.

what I mentionned above is just the geometry / mesh side (no physics).
How they move, can you explain later in fluent (not in gambit)

not like that.
Substract your solid region (you should have empty area instead of solid impeller)
Then if your geometry enables it, draw (split) a circle around your rotor.
You have now 2 regions,...

The easiest way would be to treat your problem with sliding mesh.
Basically you need 2 regions which are not connected: rotor and stator, and then define interfaces
