Low power three-phase synchronous alternator
14 - 28 V, 18 - 35 A | AAG

Low output powers make it possible for the
alternators to be built into systems with low
electrical requirements. Small dimensions allow
installation on all types of combustion engines
used on small tractors, small agricultural
machinery, stationary engines and some other
applications.
D E S I G N
The alternator is a three-phase, 12-pole
synchronous self-excited generator with builtin
rectifier and regulator and cooled by an
external fan. Various design solutions are
available depending upon the application:
insulated, marine, dustproof and other versions.
C o o l i n g
The integral fan provides effective through cooling
of the alternator. Two different fans are available,
for CW and CCW direction of rotation.
R o t o r
The rotor winding fixed between the claw poles
provides excitation of the alternator through slip
rings. For particularly dusty environments slip rings
and brushes are additionally protected.
R e c t i f i e r
Press fit Zener diodes are mounted into protected
heat sinks. Zener diodes protect the loads on the
vehicle against overvoltages from the alternator.
R e g u l a t o r
The monofunction regulator incorporating the brush
holder is built into the alternator. The regulator
is produced using thin-film hybrid technology.
The highest quality brushes ensure long life
of the alternator.

Brackets, bearings and pulleys are made according
to the customers' requirements. A range of special
sealed bearings makes it possible to design
alternators for specific installations, operating in
the harshest conditions whilst achieving long,
maintenance free life.
