GENERAL FEATURES:

Apart from guaranteeing the characteristics of the preceding series, such as assuring a permanent short circuit current above or equal to 3 times the nominal current, the ECO series has also been improved. As far as its mechanical components are concerned, the end-brackets have a new shape to improve ventilation, the coupling to the prime mover is simpler and the terminal boxes are bigger to simplify the connection of the electric cables.

As for the electric components, the electronic regulators are always updated to improve their performance and reliability, with the possibility to interchange them with the previous ones. All the ECO alternators have a fixed inductor with skewed slots and a rotating inductor fitted with a damper cage (except for the ECO3/4 and ECO28/4 alternators.) The windings have a 2/3 pitch in order to reduce the harmonic content of voltage. The entire series is manufactured according to and complies with the most common specifications such as CEI 2-3, IEC 34-1, EN 60034-1, VDE 0530, BS 4999-5000, CAN/CSA-C22.2 N˚ 14-95 – N˚ 100-95; special versions are available on request to meet specific specifications and regulations.
