EXCITATION
The marine range has an excitation 
system requiring neither ring nor 
brush. The AREP system, enables 
short-circuit current to be maintained 
at 300 % for a period controlled by 
the regulator and limited to 10 
seconds. PMG excitation is also 
available as an option.
CONSTRUCTION
- Rigid steel casing.
- Rotors are dynamically balanced  
with 1/2 key (ISO 8821), conform to 
class G 2.5 (ISO 1940).
- Squirrel damper winding in the 
rotor for parallel operation.
BEARINGS
- Sealed for life bearings for models 
up to the LSA M 47.1 L10
H
 life of 
20,000 hours (ISO 281)
- Regreasable bearings for LSA M 
49.1 to LSA M 51.2 L10
H
 life of 
40,000 hours (available as an option 
on LSA M 44.2, 46.2 and 47.1).
PROTECTION
- IP 23 enclosure as standard
 (IP 44 or IP 55 on request)
- Thermal protection can be installed 
in the windings or end shields.
CAPABILITY
LEROY-SOMER is a world leader with the most comprehensive range of alternators 
on the market  : from 1 to 25000 kVA for speeds of 300 to 3600 mn
-1
For marine use, LEROY-SOMER has a compact, sturdy range which operates either 
as a main power supply or as an auxiliary generator, in continuous duty or on 
standby.
STANDARDS & CERTIFICATION
LEROY-SOMER alternators conform to IEC recommendations 34-1 and other 
international standards : NFC 51-111, UTE 5100, VDE 0530, BS 5000, IEC 2.3, 
NEMA, IEEE, CSA, etc.
Alternators for marine use are supplied with certificates issued by the following 
international organisations. LSAM range is approved by organisations marked with (*).
