Wind generators - The heart of the wind turbine 

Without generators, it would be impossible to convert the mechanical energy of the rotor blades of a wind turbine into electrical energy. In general, there are three different types of construction that are used in the wind turbine. The asynchronous generator dates back to the early days of wind power and is now often found in plants on the secondary market. The advantage of the robust, cost-effective and low-maintenance design is offset by the disadvantage of a narrow speed range. These new or used generators are therefore designed for only one wind speed, so that adaptation is hardly possible.   In contrast to the synchronous generator, however, the asynchronous generator can be connected directly to the grid without an inverter. Synchronous generators can operate in a wide speed range and are primarily used in gearless wind turbines. A double-fed asynchronous generator, on the other hand, is part of the concept of a variable-speed rotor, which has adjustable rotor blades, the so-called pitch control.

Wind turbines with various types of wind turbine generators on wind-turbine.com

As an international marketplace, wind-turbine.com offers the opportunity to buy and sell used wind turbines with wind generators of different designs. Project developers can thus benefit from wind turbines on the secondary market in several ways: If older turbines are no longer needed, for example due to repowering, they can find a new use at another location at a lower price and, depending on the wind conditions, even work more efficiently than at the place of origin. At the same time, a discarded wind turbine does not have to be disposed of at a cost. Both buyers and sellers thus benefit greatly from the opportunity to wind-turbine.com to trade a used wind turbine at fair prices.
