ALTERNATORS

The technical performance of Iskra alternators is based on long-term relationships with the customers, their highrequirements and expectations and our own long-standing experience in development and production. We control quality using standard ISO 9001 : 2000. The entire process from customer requirement and expectation, through development and production is planned and controlled in detail. High operating reliability is assured by optimising the design for use in different operating conditions, together with numerous validations of different alternators in Iskra's own laboratories and on vehicles.Alternators are air-cooled synchronous three-phase generators with claw poles and a built-in semiconductor rectifier.A three-phase stator winding is connected to the three-phase rectifier bridge with power rectifier or Zener diodes. The rotor coil is connected to the slip rings with brushes that conduct the excitation current. Alternators are self- excited through excitation diodes or they are excited directly by the battery. The voltage regulator can be either built- in or separately mounted. The negative terminal is normally connected to the chassis.Iskra Avtoelektrika keeps abreast of all technical innovations in the field of alternators. Its staff are aware that energyconservation in vehicles is an absolute necessity. The results are different families of alternators designed in modern compact versions with internal fans in parallel with families of conventional design using external fans. Modern versions of rectifiers and specific multifunction regulators are also available.Different versions of alternators meet very high specifications in terms of resistance to salt spray, humidity, water,mud, dust, vibrations, high and low temperatures and aggressive liquids. They are also designed to meet electromagnetic compatibility and other international directives and standards. They are produced using ecologically sound technologies and environmentally friendly materials.Iskra alternators are designed to meet a wide range of engineering specifications and applications. They are usedon petrol and diesel engines in the automotive industry, on trucks, buses, tractors, construction machinery and in other applications. Different solutions of our alternators are defined taking into account the demands of each application and are designed for long life, maintenance free operation under extreme conditions.
