Direct-drive generators are an attractive candidate for wind power application since they do not need a gearbox, thus increasing operational reliability and reducing power …
Our generators are the perfect solution wherever power has to be generated reliably and efficiently – whether in an industrial plant, a large gas or steam power plant or for the greed fed by renewables. Our generators cover a power range …
When calculating the total number of cycles experienced by the shaft during the design life of the turbine, it is assumed that the rated frequency, design life, and probability of operation (taken from Weibull parameters and cut-in/cut-out wind speed) can be multiplied to give an approximate lifetime number of shaft rotations.
A wind turbine''s hub height is the distance from the ground to the middle of the turbine''s rotor. The hub height for utility-scale land-based wind turbines has increased 83% …
The rotor connects to the generator, either directly (if it''s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force …
In this article, we aim at introducing some specifications of modern wind turbines like the latter ones. In this article, we will talk about four main specifications of wind turbine generators: rotor diameter (RD), tip height (TH), tip clearance (TC), and hub height (HH).
A modern wind turbine generator has as many as 8,000 different components . Wind turbines are soaring to record sizes. The average rotor diameter of turbines installed in 2018 grew to 115.5 meters, up 141% since 1998–1999. There is also an increase in the average nameplate capacity of turbines, meaning they have stronger generators.
The lift generated as wind passes over the blade causes it to move, thereby rotating the main shaft. The rotation is transmitted through a gearbox to a generator, which converts it into electricity. The magnitudes of …
The rotating blades make a shaft turn inside the nacelle, which goes into a gearbox. Next, the gearbox speeds up the rotation to an appropriate level for the generator, which uses magnetic fields to convert the rotational …
Wind turbines operate in some of the harshest environments on earth. From the turbulent winds of coastal regions to the fluctuating temperatures in deserts, these structures …

The nacelle houses the gearbox and generator connecting the tower and rotor. Sensors detect the wind speed and direction, and motors turn the nacelle into the wind to maximize output. In conventional wind turbines, the blades spin a shaft that is connected through a gearbox to the generator. The gearbox converts the turning speed of the bla…
The stator laminations of large permanent magnet synchronous wind generators are often sectionalized and overlapped, which will cause the magnetic circuit asymmetry. ... Full size …

The average rotor diameter of turbines installed in 2018 grew to 115.5 meters, up 141% since 1998–1999. There is also an increase in the average nameplate capacity of turbines, meaning they have stronger generators. In 2020, utility-scale wind turbines with 2.75 megawatts (MW) capcity were installed, 8% up from the previous year .
of wind turbine generators at offshore sites have increased, leading to the introduction of multi-megawatt wind turbine generators. A bigger bearing size and a various type of bearings are …
