LSA 42.2 - 2 & 4 POLE
ALTERNATORS
3433 en - 2010.10 / g
LEROY-SOMER
4.7 - Electrical characteristics table
Table of average values:
Alternator - 2 and 4 pole - 50 Hz/60 Hz - Standard winding
n°6 and M or M1 in dedicated single phase (400 V for the
excitation values).
The voltage and current values are given for no-load operation
and operation at rated load with separate eld excitation. All
values are given at ± 10% and may be changed without prior
notication (for exact values, consult the test report). For 60 Hz
machines, the “i exc” values are approximately 5 to 10 %
lower.
