AS-PL offers more than 4 100 types of alternators for various vehicles: passenger cars, lorries, agricultural machines, boats, motorcycles, and for the industrial market. Such a wide selection of products enabled the company to become one of the leading suppliers in the worldwide spare parts industry.


Alternator – operating principle

An alternator is an AC used to change mechanical energy into alternating current. Inside an alternator, electric current is produced in stator windings by the rotating magnetic field of a rotor. It is commonly used in mechanical vehicles as a source of electricity. Nowadays, alternators are digitally controlled so their quality control requires using state-of-the-art machinery.

A battery is an inherent component of both older and modern vehicles. A battery that supplies electricity to the whole vehicle requires charging. This is where an alternator comes in handy. The first alternator was constructed and patented by Nikola Tesla in the USA in 1891. Currently, every single car is equipped with one.


Quality control

Products offered by the company undergo strict testing procedures and meet the highest requirements in relation to their assembly and technical parameters. All alternators and starters offered by the company are tested using specialist machinery. The test results are included in the product packaging. Supplying reliable products tailored to current market expectations while using state-of-the-art technologies is the company's crucial goal and mission.


Online catalogue

In order to meet our Customers’ needs and expectations, we created an online catalogue that enables them to search for necessary parts quickly and easily. The catalogue is available at: and on the company website.

To reduce our carbon footprint, we decided to not provide printed catalogues. A specialist mobile application, AS-PL Catalogue, is available in order to facilitate selection of the proper components. You can download it from Google Play™ and App Store®. The “AS” brand is also available in the TecDoc catalogue under the name AS-PL.
