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