feldorientierten

Feldorientierten is the inflected form of the German adjective feldorientiert, which means field-oriented in English. It is used to describe approaches, methods or systems that orient or align to a field, most often an electromagnetic field or a vector field in physics and engineering. In technical usage the adjective typically modifies a noun such as Regelung (control) or Ansatz (approach).

The best-known expression is feldorientierte Regelung, commonly abbreviated as FOC (field-oriented control). This control strategy is applied in drive technology for electric motors, notably brushless DC motors and induction motors, to decouple torque and flux by transforming quantities into a rotating reference frame aligned with the rotor flux. The result is improved dynamic response and easier, more accurate control of motor torque and magnetic flux. The concept can also appear in related terms such as feldorientierte Analysen or feldorientierte Modellierung, where analyses or models are conceived with respect to a field, for example an electromagnetic field or a stress field.

Grammatically, feldorientierten is one of the inflected forms of feldorientiert. It can occur in contexts such as the dative singular masculine or neuter (dem feldorientierten Motor) or in plural forms (die feldorientierten Ansätze). The exact meaning is determined by the surrounding noun and case, as with other German adjectives.

In German-language technical literature, feldorientierten and feldorientierte forms are common in discussions of field-oriented methods and their applications in engineering and physics. The underlying concept—orienting analysis or control to a field—remains the same across contexts.
