press release

Bosch now has a new alternator for commercial vehicles in its portfolio. Designed for the lower power segment, the models of the Classic Line series deliver currents from 70 to 150 amperes at 14 volts, and 50 to 80 amperes at 28 volts, depending on variant. The alternators stand out for their improved electrical layout, with high levels of efficiency and an extremely robust design. They can also be used in off-highway applications. The alternator’s performance characteristics and cost-effective design mean that Bosch is positioning its new model especially in the emerging markets of South America, eastern Europe, and Asia, but also in the lower power segment in western Europe and the United States. Series production started in China this year, with production in other countries to follow shortly.

The high level of efficiency, which can exceed 70 percent, is a novelty in this performance class. For example, it has allowed the alternator’s design to be especially compact: without the belt pulley, its length is just 125 millimeters. If power requirements are the same, this creates additional space in the engine compartment. Alternatively, engineers have the benefit of greater power from an alternator of the same size. Moreover, fuel consumption is reduced, and thus emissions as well.

Long-lived and rugged
Several features ensure smooth operation, also off-road. An internal fan keeps the alternator sufficiently cooled, the slipring system is especially well protected against spray and dirt, and the end shields and bearings have been reinforced. The result: a service life of 400,000 kilometers or 7,500 hours of operation.

When developing the new Classic Line, Bosch also had the world’s growth markets in its sights, where there is a demand for affordable yet high-quality products. Following the initial start of series production in China, therefore, production of the new alternator series will now start in quick succession in Hungary, India, Brazil, and Mexico, where it will gradually displace its predecessor models. For commercial vehicles requiring higher power, Bosch still has the models from its heavy-duty series in its portfolio.
