Figure 227: Chronological sequence of the motor l
2
t actual value in the nominal operating point
The chronological sequence of the l
2
t model during nominal current is presented in ZFig.
227. The standardization of the l
2
t model corresponds to 40°C 0% (maximum value
of the environmental temperature) and the maximum thermal load of the motor 100%.
The maximum thermal load of the motor corresponds to the continuous load of the motor.
The maximum thermal load of the motor
In general the maximum thermal load (and accordingly the maximum operating tempera-
ture) corresponds to the maximum permissible continuous temperature of the winding.
The maximum load and the operating temperature however can be limited by other fac
-
tors. Contact the motor manufacturer for more detailed information.
The maximum permissible continuous temperature of the winding depends on the insu-
lation class of the motor. It results from the permissible temperature increase plus a
hotspot safety margin and refers to a specified maximum environmental temperature of
40°C. The maximum continuous temperature NEMA motor insulation class F is 155°C,
for example. That means that a motor with insulation class F 155°C has the standardiza

NOTE!
The overload monitoring applies to motors used for continuous operation (S1) at a
maximum environmental temperature of 40°C and set up under 1000
m altitude. If
these motors should be used within an environmental temperature of more than 40°C
or in heights over 1000
m altitude, then the motor nominal power Z107.6 and the
motor nominal current Z107.9 must be accordingly minimized. For this purpose the
motor manufacturers provide the accordant derating factors.
