Synchronous Alternators
WEG was established in 1961 and is one of the largest manufacturers of alternators in Latin America
and of electric motors in the world. With extensive experience in the sector, WEG offers a wide range of
alternators to meet the requirements of different applications in virtually any environment.
The alternators are specially designed according to the specific characteristics of each application so as
to meet the customer’s needs: generator sets, wind turbines, turbogenerators (steam or gas) and
hydrogenerators.
Output (kVA)
WEG offers the customer after sales technical support in applications and installations by means of its
specialized customer service network.
This document presents WEG alternator options and applications in generator sets driven by internal
combustion engines (diesel, gas, biodiesel, ethanol, oil, gasoline, bi-fuel etc.).
The use of a generator set ensures power supply regardless the power grid, which makes WEG
alternators an excellent solution for emergency or continuous operation in maritime and ground
applications.
