alternators are designed to meet a wide range of engineering specifications and applications. They are used on petrol and diesel engines fitted in trucks, buses, agricultural and construction machinery as well as in the automotive industry. The product range includes two basic designs with regard to the cooling of the electric motor: compact alternators with internal fans and classic alternators with external fans. Individual families of alternators are available with 14 V and 28 V DC rated voltage and output current up to 270 A.
External fan alternators are specially designed for operation under adverse environmental conditions, such as dust, mud, salt, high-frequency vibrations, and high electrical and thermal load, which are standard for agricultural and construction equipment. Compact alternators are designed for a wide range of applications where lower noise, compact design, and operation at higher rotational speeds are specifically required; for example, in automotive and commercial vehicle applications.
