Direct Drive Wind Turbine Market - Global Industry Analysis, Size, Share, Growth, Trends, and Forecast 2016 – 2024
Direct drive wind
turbines, also known as gearless wind turbines, are wind turbines
without a gearbox. The rotor shaft is directly
connechttps://www.transparencymarketresearch.com/sample/sample.php?flag=CR&rep_id=39ted
to a synchronous or permanent magnet generator for power generation.
Direct drive wind turbines usually use either permanent-magnet
excited direct drive generator system or electrically excited direct
drive synchronous generator system depending upon cost, location, and
other constraints. Direct drive wind turbines are better alternatives
for offshore applications, as they require less preventive and break
down maintenance vis-à-vis geared wind turbines. Furthermore, most
direct drive wind turbines are contactless and contain fewer parts.
Operation and maintenance is also more expensive for offshore farms
as compared to their onshore counterparts. This ultimately increases
the overall reliability of turbines and wind farms.
Increase in demand
for energy, especially renewable energy, across the globe is one of
the major factors driving the direct drive wind turbine market.
Direct drive wind turbines are viable alternatives for offshore wind
farms due to high reliability and lower maintenance costs.
Furthermore, offshore winds farms eliminate several severe problems
caused by windmills such as noise pollution and ecosystem damage. The
overall weight of direct drive wind turbines is substantially low as
compared to that of its geared counterparts. Gearless wind turbines
are also noticeably efficient. This further reduces operating costs
and increases the energy output. However, the cost of setting up
direct drive wind turbines is relatively high due to the substantial
usage of rare neodymium magnets, technology costs, and large size of
generators. The average energy yield per unit cost of direct drive
wind turbines is also low. However, the cost of manufacturing and
setting up direct drive wind turbines is anticipated to decline in
the near future, led by the rise in demand for these turbines and
economies of scale.
Based on
application, the direct drive wind turbine market can be segmented
into onshore direct drive wind turbine and offshore direct drive wind
turbine. The offshore application exhibits significant growth
opportunities due to the various advantages offered by direct drive
wind turbines compared to geared wind turbines. Based on the capacity
of turbine, the direct drive wind turbine market can be classified
into less than 1 MW, 1 to 4 MW, and 4 MW and above segments. In terms
of generator, the market can be segregated into permanent-magnet
excited direct drive generator system and electrically excited direct
drive synchronous generator system. Both these technologies carry
certain advantages; however, electrically excited direct drive
synchronous generator systems are relatively expensive.

Asia Pacific, Europe, North America, Latin America, and Middle East &
Africa. Asia Pacific is a major market for direct drive wind
turbines; China is one of the leading countries in terms of
installation of direct drive wind turbines. Increase in demand for
energy and need for environmental protection are boosting the demand
for wind farms across the globe. Europe and North America are also
lucrative markets for direct drive wind turbines, as these regions
are investing significantly in harnessing renewable energy. Countries
such as Germany, Italy, and France have invested in direct drive wind
turbines to meet their demand for energy.
