4.7 - Installation and maintenance of
the PMG
For the LSA 43.2 and LSA 44.2, the PMG
reference is PMG 1.
See the PMG maintenance manual, ref:
4211.
Mounting is impossible with the
«regreasable bearings» option with the
LSA 44.2.
4.8 - Table of characteristics
Table of average values:
Alternator - 2 and 4 poles - 50 Hz/60 Hz -
Winding n° 6 and M or M1 connected 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 field excitation. All values
are given at ± 10% (for exact values, consult
the test report) and are subject to change
without prior warning. For 60 Hz machines,
the resistance values are the same and the
excitation current «i exc» is approximately 5
to 10% weaker.
