Endleistung

Endleistung is a German term that translates roughly as “final power” or “output power.” It is used in technical language to refer to the power that a system delivers to its load at the end of a process, as opposed to the input or internal power. The exact meaning of Endleistung is not strictly standardized and depends on the context in which it appears.

In electrical engineering, Endleistung may be used to denote the power delivered by the output stage of a device to a load. In practice, however, many sources prefer terms such as Ausgangsleistung (output power) or Nutzleistung (useful power), and Endleistung’s specific meaning can vary between documents.

In mechanical engineering and energy systems, Endleistung can refer to the shaft power or useful power produced by a drive system after accounting for losses in components like gears or transmissions. It is commonly expressed in watts or kilowatts and used to characterize the usable power available to perform work.

Relation to other quantities is important: input power (Aufnahmeleistung) is the power entering the system, Endleistung is the delivered power, efficiency (Wirkungsgrad) is the ratio of Endleistung to Aufnahmeleistung, and apparent power (S) is a different electrical quantity relevant in AC systems.

Because Endleistung is not universally standardized, its exact meaning should be clarified by the source. When precision is required, it is often better to use more specific terms such as Ausgangsleistung, Nutzleistung, or Shaft power, depending on the domain.
