Torque Measurement in Wind Turbines HBM

Gear unit. In wind turbines, there is a "conflict of interests" between the rotor's drive speed, limited, for example, by pitch speed, and the required rotational speed of the generator.With two pole pairs, a rotational speed of 1500 rpm is required for a mains frequency of 50 Hz. [4]. The solution is to use a gear unit. Gear units convert rotational speed and torque and transmit high power.

Wind energy Open Energy Information

Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth's surface, and rotation of the earth. Mountains, bodies of water, and vegetation all influence wind flow patterns, . Wind turbines convert the energy in wind to electricity by rotating propeller-like blades around a rotor. The rotor turns the drive shaft, which turns an electric generator.
