Nennlinien

Nennlinien, also known as rated curves or characteristic curves, are graphical representations used in engineering to depict the performance or operational limits of a component, device, or system under various conditions. These curves typically plot one or more output parameters against one or more input parameters. For example, a motor's Nennlinie might show its torque output as a function of its rotational speed. Similarly, a pump's Nennlinie could illustrate its flow rate at different head pressures.

The primary purpose of Nennlinien is to provide a clear and concise overview of how a system behaves and to define its intended operating range. They are crucial for selecting appropriate components for a given application, ensuring proper system design, and troubleshooting performance issues. By examining a Nennlinie, engineers can quickly understand a device's capabilities, identify potential bottlenecks, and avoid operating outside of its designed specifications, which could lead to damage or reduced efficiency. The curves often highlight maximum or minimum thresholds, recommended operating zones, and specific operating points.
