■
Standard ambient temperature of the geared motors
The SIMOGEAR geared motors can be deployed in the following
standard ambient temperature ranges:
■
Increased protection against humidity and tropical climates
Increased protection against humidity and tropical climates can
be optionally supplied for the (geared) motors, frame sizes 63 to
200. This design is suitable for air humidity in the range between
30 and 60 g water per m³ air as a function of the temperature
(
see page 6/8
).
The increased protection against humidity and tropical climates
includes surface treatment with corrosivity category C2 (
L03
),
increased winding protection against moisture and acid (
N54
)
and internal motor corrosion protection (
N41
).
Please contact Siemens, if the motor requires other functions
(brake, backstop, encoder systems).
■
Extreme ambient temperatures
When operating the SIMOGEAR geared motors outside the
specified standard ambient temperatures, the geared motors
must be adapted to the special environmental conditions.
Please contact Siemens in this regard.
