The turbine shaft of a wind turbine generator is
The drivetrain on a turbine with a gearbox is comprised of the rotor, main bearing, main shaft, gearbox, and generator. The drivetrain converts the low-speed, high-torque rotation of the turbine’s rotor (blades and hub assembly) into electrical energy.
The drivetrain on a turbine with a gearbox is comprised of the rotor, main bearing, main shaft, gearbox, and generator. The drivetrain converts the low-speed, high-torque rotation of the turbine’s rotor (blades and hub assembly) into electrical energy.
The turbine generator is the component that turns the rotational energy in the high-speed output shaft from the gearbox into an electrical current. The electrical principle of electromagnetic induction shows that while a magnet is moving past a coil of wire, an electric current is created (or “induced”) in the wire.
Wind turbine power output is variable due to the fluctuation in wind speed; however, when coupled with an energy storage device, wind power can provide a steady power output. Wind turbines, called variable-speed turbines, can be equipped with control features that regulate the power at high wind velocities.
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
A major turbine part among these components is the generator and the turbine shaft that transfers the harvested power from wind to the generator through a gearbox. The gearbox is a vital component of wind turbines; it resides in the nacelle.
