Morphology
The phrase is compositionally built from 'synchronous' (occurring at the same time/in phase) and 'motor' (a device producing motion), so a learner who knows both words can infer it refers to a motor that runs in sync with the power supply. The precise engineering detail about speed being proportional to AC frequency is technical but does not prevent the basic meaning being transparently derivable from the constituents.
Etymology
Synchronous motor gets its name because synchronous means 'at the same time' and the motor turns in time with the electric 'beat' of the power. So, it keeps a 'constant speed' that matches the electricity.
