F03D 9/10

Combinations of wind motors with apparatus storing energy

Introduced: January 2016

Full Title

Full titles differ between systems:

IPC:

Adaptations of wind motors for special use; Combinations of wind motors with apparatus driven thereby; Wind motors specially adapted for installation in particular locations > Combinations of wind motors with apparatus storing energy

CPC:

Adaptations of wind motors for special use; Combinations of wind motors with apparatus driven thereby; Wind motors specially adapted for installation in particular locations (hybrid wind-photovoltaic energy systems for the generation of electric power H02S10/12) > Combinations of wind motors with apparatus storing energy

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

IPC defines codes here since 2016.
