Lagerwey’s next generation of direct drive
Durability
Durability begins with a quality product. Lagerwey's
newestgeneration of direct drive turbines is ready for the
futureand is challenging the old concepts in many
aspects.Lagerwey’s long experience and innovative mind
regardingdirect drive technology has resulted in an optimal next
generation turbine called the L82. Reducing the amount of
components and design simplicity are essential drivers in
making durable quality.Technology
The turbine has a permanent magnet generator withexcellent
efciency in partial and full load. Together with afull power
converter we are able to deliver a clean, gridfriendly power during
worst case circumstances.
Due to the variable speed principle, the turbine is the best
choice when conditions get rough. An advanced electricalpitch
system reduces the loads and guarantees a maximumenergy capture.
The only moving part with a high loadcycle is the main bearing
where Lagerwey deliberately engineered a comfortable safety margin
regarding wear and loads. The automatic lubrication system is
closely monitored and is very accessible for maintenance.
The L82 has an hollow main shaft for direct access to thehub.
This makes the design light together with high stiffnessto
withstand the loads. All service can be done comfortably from the
inner side of the turbine.
The generator is closed from outside inuences and has anefcient
passive cooling system that makes her withstandthe most severe
environments (dust, coastal operation etc.).
Transportation and installation cost have become mayor costs in
the multi megawatt turbine class. Our concept withready to t
assembly modules enables low installation cost and requires minimal
crane capacity. The turbine can beerected with a 500 ton mobile
crane.
The L82 energy capture is very high, especially there where it
matters, in partial load. In partial load the L82outperforms the
existing drive train concepts by far.
Design margins and low installation and maintenance cost make
the turbine a low risk investment and combined withthe excellent
energy capture allows for an attractive returnof investment. This
is the turbine of choice for your projects.
