ELECTRICAL CHARACTERISTICS

PARTNER LSA 49.1 alternator is a machine without
sliprings or revolving field brushes, wound as "2/3 pitch";
6 or 12-wire, with class H insulation and a field excitation
system available in either AREP or "SHUNT+PMG"
version (see diagrams and AVR maintenance manual).
• Electrical options
- Stator temperature detection sensors
- Space heaters
- Terminal box with connector links for mounting
protection or measurement C.T.
In order to conform to standard EN 61000- 6.3, EN
61000-6.2, the R 791 interference suppression kit is
needed.

MECHANICAL CHARACTERISTICS

• - Steel frame
- Cast iron end shields
- Greasable ball bearings
- Mounting arrangements:
IM 1201 (MD 35) foot and flange mounted, single-
bearing with SAE coupling disc.
IM 1001 (B 34) double-bearing with SAE flange and
standard cylindrical shaft extension.
- Drip-proof machine, self-cooled
- Degree of protection: IP 23
• Mechanical options
- Protection against harsh environments
- Air inlet filter, air outlet labyrinth seals: IP 44
To prevent excessive temperature rise caused by
clogged filters, it is advisable to monitor the stator
winding with thermal sensors (PTC or PT100).
