■ Overview
Explosion-protected motors
For converter operation of Ex motors, special measures must be
considered, see Chapter 5.
DURIGNIT IR 2000 insulation system
The DURIGNIT IR 2000 insulation system consists of high-quality
enamel wires and insulating sheet materials in conjunction
with temperature-resistant resin impregnation.
This ensures that these motors will have a high mechanical and
electrical strength, high service value, and a long lifetime. The
insulation system protects the winding to a large degree against
aggressive gases, vapors, dusts, oils and increased air humidity.
It can withstand the usual vibration stressing. The insulation
is suitable up to an absolute air humidity of 30 g water per m 3 of
air. Moisture condensation should be prevented from forming on
the winding. For higher values, the N30 and N31 options are
available – see page 1/28.
Please inquire about extreme applications.
Restarting against residual field and opposite phase
All motors can be restarted against 100 % residual field after a
line voltage failure.
Winding and insulation version with regard to temperature
class
At rated power in line operation, the 1LE5/1MB5 motor series
can be utilized in the following temperature class:
• For SIMOTICS SD Add 1) : Temperature class 130 (B)
• For SIMOTICS XP 1) : Temperature class 130 (B)
• For SIMOTICS SD Pro and SIMOTICS XP 1MB58:
Temperature class 155 (F)
All motors are designed with temperature class 155 (F).
For details of derating for utilization in temperature class 155 (F),
see "DURIGNIT IR 2000 insulation system".
Temperature class 155 (F), utilized according to 155 (F),
with service factor (SF)
According to the selection table, at rated power and rated voltage,
all 1LE./1PC1 motors in line operation have a service factor
of 1.15. An exception are IE1 motors, which have a service
factor of 1.1.
For the line operation, all motors with frame sizes 400 and 450
have a service factor of 1.05 at rated power.
Order code N01
Temperature class 155 (F), utilized according to 155 (F),
for higher power
When utilized according to temperature class 155 (F), the rated
power specified in the selection and ordering data can be increased
by 15 %. Exception for IE1 motors – can be increased
by 10 %. For motors of frame sizes 400 and 450, for line
operation, when utilized according to temperature class 155 (F),
the rated power listed in the selection and ordering data can be
increased by 5 %. In this case, the service factor is 1.0.
Order code N02
Temperature class 155 (F), utilized acc. to 155 (F),
with increased coolant temperature
With power as defined in the catalog and line operation, the
coolant temperature is permitted to rise to 55 °C and, for motors
of frame sizes 400 and 450, to 45 °C.
In this case, the service factor is 1.0.
