Asynchronous generators

Asynchronous generators are important components in energy production that convert mechanical energy into electrical energy. These generators, also known as induction generators, are particularly valued for their robustness and reliability and have a wide range of applications in industry and in the field of renewable energies.

Features

Asynchronous generators are characterized by their simple design and low maintenance requirements. They consist of a rotor and a stator, with the rotor usually being a squirrel-cage type. These generators can be operated without additional synchronization equipment, which simplifies their handling and integration into existing systems. They are available in various power and voltage ranges, increasing their flexibility and adaptability to different requirements. Their thermal stability and high efficiency make them a reliable choice for numerous applications.

Applications

Asynchronous generators have a wide range of applications. In power generation, they convert the kinetic energy of the wind into electrical energy. They are also frequently used in smaller hydroelectric power plants. Furthermore, they are used in industry to recover braking energy in electric drives. In remote or off-grid areas, they ensure a reliable power supply when combined with diesel engines. Their versatility and robustness make them a preferred choice for a wide variety of power generation projects.

Our range of services

The asynchronous generator represents a reliable, cost-effective, and easy-to-maintain alternative to the conventional synchronous generator for the use of renewable energy sources such as wind and hydropower, even in small and medium-sized installations. Depending on the application, asynchronous generators are operated on their own dedicated grid or in parallel with an existing grid. The existing G21R/G22R series have now been supplemented by the GE1R/GE2R series, whose design is based on the IE2 series of asynchronous motors.
