Is it possible to create Radial scrolling UV motion without scaling? Inorder to show the winddirection in a turbine animation, the UVs (parented empties with  a UV wrap modifier) are to be scrolled radially .
Scaling the empties does provide radial motion but it scales them as well.

It's hard to say in detail without knowing exactly what you need, but some variation on this might serve your purpose:

Here, the nodes are being used to control simple color bands, keying the offset on Length, but they could be used to control the UV look-up of a suitably mapped texture, for hand-drawn, or other effects
