LEROY-SOMER offers a range of alternators that arePOWER range alternators are produced on a 25,000 m2 dedicated site atperfectly suited to market requirements.ORLEANS (France). This site incorporates high-performance production toolsPOWER range alternators cover a power range from 1 to 20specific to the alternator application: stamping magnetic laminations,MW responding to the most demanding operatingmachining, mechanical welding, winding, impregnation under high vacuumconstraints: speed of rotation (333 rpm to 1800 rpm) andadaptation to various drive systems voltages from 380 V to 15 kV healthy or extreme environmental conditionsand pressure.The plant production output is organised so as to satisfy the most stringentdemands for quality and short delivery times, while dealing with a wide rangeof alternator dimensions and weights (2 to 80 tonnes).(humidity, corrosion, etc).A high-performanceindustrial toolPoweracross the whole rangePOWER range alternators: modularity to adaptbetterThe originality of POWER range alternators lies in their modulardesign which enables them to adapt to all types of application,but also to all environments.From a basic module, LEROY-SOMER engineers can createalternators which match the requirements of packagers and finalusers perfectly.Go for reliabilityAn in-depth knowledge of the processes, continuous monitoringthroughout the process and thorough testing of all products beforedespatch, guarantee the quality of POWER range alternators.This high level of quality is demonstrated by the achievement of ISO9001 certification from the DNV, which has been held since 1994.
