rotary motion singular

Morphology

rotary + motion

The meaning 'movement in which an object rotates around an axis' is directly and transparently derived from combining 'rotary' (moving by rotation) with 'motion' (movement). This is a straightforward compositional compound following normal English adjective + noun patterns and is cross-linguistically common, so a B1 learner who knows the constituents would understand it.

Etymology

Rotary motion comes from the simple picture of a wheel or fan turning around its center again and again. Here rotary means 'turning' and motion means 'movement', so the phrase describes 'movement in which something turns around a center point'.
