Asynchronous generatorsprices on 3 models
Asynchronous— the asynchronous alternator is called so because the rotor (rotating part) in such mechanisms, during rotation, somewhat outstrips the movement of the magnetic field created by the stator (fixed part). This is the simplest and most inexpensive type of alternators, which is also distinguished by high reliability, good protection from external influences and insensitivity to short circuits and prolonged overloads; the latter allows, in particular, the use of such generators with welding machines. However, nowadays, alternators of this type are used quite rarely, for which there are several reasons at once. Firstly, asynchronous units are mainly designed to power active loads such as lighting or appliances with electric heaters, they do not tolerate reactive loads that consume very high currents (for example, electric motors) when starting up. Secondly, the voltage and frequency of the output current in such models directly depend on the speed of rotation of the engine, and it is technically difficult and does not make sense to provide automatic adjustment. Thirdly, for electric welding, you can use not only a generator and a separate device, but also a specialized welding generator (see "Functions and Capabilities"), which allows you to do without a separate device; and such specialized generators are made mostly synchronous.
