COMPANY INTRODUCTIONSectors of interest and products: ENERGY
UmbraGroup property informationwww.umbragroup.it
The challenges involved in maximum powerextraction suggests that direct drivegenerators could be a viable alternative tothe more used hydraulic systems.
Reciprocating Linear Alternators have beenproposed as a suitable power take-off systemfor a straightforward applicability to sometype of WECs such as Attenuators, OWSCsand Point Absorbers.
Electro Mechanical GeneratorPower generator sizes:
5KW to 250KW
(the linear generator is fully reversible)
COMPANY INTRODUCTIONSectors of interest and products: OCEAN ENERGY
UmbraGroup property informationwww.umbragroup.it
R&D BACKGROUNDConcept
Garcia-Rosa, P. V. S. Cunha, Lizarralde “Efficiency Optimization in a Wave Energy Hyperbaric Converter”.
EMGs drastically shorten the conversion chain between the prime mover and the grid: the introduction of the ballscrew in the
system allow to pass directly from a reciprocating linear motion into an rotary electrical generator.
Advantages are the complexity reduction and overall reliability increase.
