Spin energy raters conceal (6)
I believe the answer is:
gyrate
'spin' is the definition.
('gyrate' can be a synonym of 'spin')
'energy raters conceal' is the wordplay.
'conceal' indicates the answer is hidden within the clue.
'GYRATE' can be found hidden inside 'energy raters'.
(Other definitions for gyrate that I've seen before include "Spiral about a point" , "Spin round" , "Move rapidly in a circle" , "Dance wildly" , "Move in a circle or spiral" .)
