Recommended operating range
Continuous operation
In observation of above listed thermal resistances
(lines 19 and 20) the maximum permissible rotor
temperature will be reached during continuous ope-
ration at 25°C ambient.
= Thermal limit
Short term operation
The motor may be briefly overloaded (recurring).
Motor with high resistance winding
Motor with low resistance winding
