How do turbine blades work?

Part of the turbine's drivetrain, turbine blades fit into the hub that is connected to the turbine's main shaft. The drivetrain 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.

How does a turbine drive a generator?

Part of the turbine's drivetrain, the main bearing supports the rotating low-speed shaft and reduces friction between moving parts so that the forces from the rotor don't damage the shaft. Part of the turbine's drivetrain, the high-speed shaft connects to the gearbox and drives the generator.

What is a rotor blade in a wind turbine?

The rotor blades are the three (usually three) long thin blades that attach to the hub of the nacelle. These blades are designed to capture the kinetic energy in the wind as it passes, and convert it into rotational energy. The largest wind turbines being manufactured in the world (as of 2021) are 15MW turbines.
