Drehfeld
Drehfeld is a German term that can refer to different concepts depending on context. The word is a compound of drehen, meaning to turn or rotate, and Feld, meaning field. In technical usage, Drehfeld commonly denotes a rotating or turning field, most notably the rotating magnetic field that underpins the operation of polyphase electrical machines. In three-phase systems, the phase-displaced currents produce a magnetic field that rotates in time, enabling torque generation in induction motors and similar devices. The term is used in German-language textbooks and engineering literature to describe this phenomenon, and it appears in historical discussions of early electric motor development.
