Torque Measurement in Wind Turbines

How much torque does a 500kW wind turbine shaft experience?

You needn''t work backward. 500kW is flowing from the blades to the generator and therefor every shaft in that path handles 500kW. Apply the formula to each shaft using the correct speed for each shaft. However the actual peak torque may be much higher as alzee76 says. A 10 cm shaft will handle the (corrected) blade torque.

Horizontal-Axis Wind Turbine (HAWT) Working Principle | Single Blade

The rotor receives energy from the wind and produces torque on a low-speed shaft. The low-speed shaft transfers the energy to a gearbox, high-speed shaft, and generator, which are enclosed in the nacelle for protection. The blades for this wind turbine will be 164 meters (538 feet) in diameter and will have a rated capacity of 8 megawatts

Why Turbine Blades Move There are two important reasons why wind turbine blades are able to spin in the wind: Newton''s Third Law and the Bernoulli Effect. Newton''s Third Law states that for every action, there is an equal and opposite reaction. In the case of a wind turbine blade, the action of the wind pushing air against the blade causes the

6 FAQs about [How much is the torque of the wind turbine blades]

How many blades should a wind turbine have?

The optimum number of blades for a wind turbine depends on the purpose of the turbine. Turbines for generating electricity need to operate at high speeds, but do not need much torque – these turbines generally have two or three blades, since this gives enough torque without adding the extra weight that can slow the turbine down.

How important is torque measurement in wind turbines?

This article clearly shows how important torque measurement in wind turbines was years ago and still is today. There is no power generation without rotation, hence, there is no power without angular speed and torque . Herbert Lauer: Die Windkraft meßtechnisch erfaßt, Markt&Technik No. 44 dated October 30, 1981

Do wind turbines need a lot of torque?

Turbines for generating electricity need to operate at high speeds, but do not need much torque – these turbines generally have two or three blades, since this gives enough torque without adding the extra weight that can slow the turbine down. Wind pumps need a lot of torque but not much speed, and so have many blades.

FAQs This wind turbine calculator is a comprehensive tool for determining the power output, revenue, and torque of either a horizontal-axis (HAWT) or vertical-axis wind turbine (VAWT). You only need to input a few basic parameters to check the efficiency of your turbine and how much it can earn you.

Why do wind turbines have 3 blades?

How long should a turbine blade be?

When attaching blades to the rotor hub, the best results are produced when the blade is attached at one edge, rather than in the centre. If 3 blades are used, it is possible to fit larger blades on the turbine. The maximum length to produce a good output was found (in testing) to be about 18cm; the maximum useful width, about 7cm.
