'drehen' and 'rotieren' can both mean that something moves around its own axis or around a central point. 'drehen' is the normal everyday word and fits in many situations: a wheel turns, someone turns their head, you turn a knob. 'rotieren' sounds more technical or precise and often describes a steady, continuous rotating movement, for example with machines, planets, or rotors. Learners may confuse the words because their basic meanings are very close. In everyday language, 'drehen' is usually more natural; in technical or factual descriptions, 'rotieren' can be more precise.
