Crossword Genius

It revolves either way (5)

Ross

I believe the answer is:

rotor

I believe this is a double definition.

'it revolves' is the first definition.
(I've seen this before)

'either way' is the second definition.

(Other definitions for rotor that I've seen before include "Revolving component" , "one lifting chopper?" , "Reversible piece of moving machinery?" , "Turning motor part" , "Part of electric motor" .)
