Morphology

rotor + shaft

The meaning is directly and compositionally derived from 'rotor' (a rotating part) plus 'shaft' (a long central/axial piece): it denotes the shaft belonging to or forming the rotor's axis. This noun–noun compound follows a common, cross-linguistic possession/part-of pattern, so a B1 learner who knows both constituents will readily infer the meaning.

Etymology

Rotor shaft comes from a simple, literal image: the rotor is the spinning part and the shaft is the long metal rod it turns on. So the name means the central rod 'around which the rotor turns' today.
