ALTERNATORS
MAIN FEATURES
ALTERNATORS
Performance of Letrika alternators is based on long-term relationships with our customers, their high requirements
and expectations and our own long-standing experience in development and production. Quality is guaranteed
by applying procedures defined in the international standard ISO 9001. All business processes from customer
requirements and expectations, through development and production to after-sales activities, are planned and
controlled in detail. High operating reliability is assured by optimizing the design for use in different operating
conditions, together with numerous validations of different alternators in our own laboratories and with field tests
on vehicles.
The requirements of the Directive 2000/53/EC – End of Life Vehicles (ELV), amended by Commission Decisions
2005/438/
EC and 2000/673/EC, which deal with prohibition and restriction of the use of some hazardous substan-
ces, entered into force on July 1, 2007, are fully met. As are the legal obligations under the EU regulation 1907/2006
on the registration, evaluation, authorization and registration of chemicals - REACH valid from June 1, 2007.
Full attention is paid to the environment as Letrika is also certified to the international standard ISO 14001.
Letrika alternators are designed to meet a
wide range of engineering specifications
and applications. They are used on petrol
and diesel engines in the automotive
industry, on trucks, buses, agricultural
and construction machinery and other
applications. Different versions of our
alternators are designed taking into account
the demands of each application and are
designed for long life, maintenance free
operation under extreme conditions.
External fan alternators are specially
designed for operation in hard
environmental conditions (dust, mud, salt,
high vibrations level and high electrical
and thermal load); for example agricultural
and construction equipment. This is due to
the design, which offers better protection
of the alternator sub-assemblies giving
the bearings and brushes a longer life, and
includes the options of additional tubes for
clean air in-take and trash screens.
Compact alternators are designed for wide
range of applications, where lower noise,
compact design and operation at higher
rotational speeds are specifically required;
for example automotive and commercial
vehicle applications.
Special versions of alternators are also
available; for example alternators for battery-
less systems used as a power supply for
A/C devices, 48V alternators are designed
as a power supply for electric motors for
E-cut, AC voltage alternators together with
electronic controlers as a power supply
for special purpose vehicles (fire trucks,
ambulance, …, where an AC voltage 110V~,
230
V~ is needed), alternators for heating
devices, … .
