Asynchronous Generators  Manufacturers, Traders, Suppliers

An asynchronous generator is based on the functionality of an asynchronous machine, whereby asynchronous generators must be magnetically excited and mechanically driven. First of all, the function of an asynchronous machine is explained below:In asynchronous machines a distinction is made between internal and external rotor machines, whereby in internal rotor machines the stator encloses the rotor and in external rotor machines the rotor encloses the stator. To put it simply, an asynchronous machine works by means of a stator winding whose axis of rotation is perpendicular to the drawing plane around the rotor (vice versa with the external rotor machine). On asynchronous machines, the rotor consists of a short-circuit cage with sheet stack, which has one or more short-circuit rods and one or more short-circuit rings. The stack of sheets completely fills the space inside the cage and consists of insulated sheets to keep eddy current losses as low as possible.The winding of the stator generates a rotating field, which enables a magnetically effective induction of the current in the rotor (induction law). The movement between rotor and stator is described by the slip circuit frequency. The magnetic field, which circulates the rotor with the slip circuit frequency, induces a voltage in the rotor. If you drive asynchronous machines faster than with the rotation frequency, then they are called asynchronous generators and can feed power into the grid.Asynchronous generators are mostly used in decentralized power plants such as wind power plants or in emergency power generators.
