Operating Range Comments
Continuous operation
In observation of above listed thermal resistance
(lines 17 and 18) the maximum permissible winding
temperature will be reached during continuous
operation at 25°C ambient.
= Thermal limit.
Short term operation
The motor may be briefly overloaded (recurring).
