Turner taking some Miro to Raphael (5)
I believe the answer is:
rotor
'turner' is the definition.
(something that turns)
'some miro to raphael' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'ROTOR' is hidden in the letters of 'miro to raphael'.
'taking' acts as a link.
(Other definitions for rotor that I've seen before include "Mechanical part that revolves, an acronym" , "Turning component" , "Turning motor part" , "Arm moving" , "Distributor arm" .)
