Direct Drive Wind Turbines

A direct drive wind turbine converts rotor rotation to electrical power directly, without the use of a gear box. Traditional wind turbines use gearboxes to step up the rotational speed (about 100x) from the rotor to the generator, which makes electrical power.

Wind turbine technology battles: Gearbox versus direct drive

This paper studies the battle between two types of wind turbines, the gearbox wind turbine and the direct drive wind turbine. Applicable determinants that affect technological dominance for the wind turbine drive trains case are identified.

How a Wind Turbine Works

Direct-drive turbines simplify nacelle systems and can increase efficiency and reliability by avoiding gearbox issues. They work by connecting the rotor directly to the generator to generate electricity.

Advanced Wind Turbine Drivetrain Trends and Opportunities

Having all of those moving parts makes the gearbox one of the highest-maintenance parts of a wind turbine. One alternative is to use a "direct drive" generator that can generate electricity at much lower speeds. Direct drive systems do not require a gearbox and therefore have fewer moving parts.
