Operating range
Comments
Continuous operation In observation of above listed thermal resistance (lines 17 and 18) and above listed ambient temperature, 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 This motor contains leaded solder. It therefore does not fulfill the requirements for the permit- ted maximum concentration of hazardous substances in accordance with the EC directive 2011/65/EC (RoHS) for all applications. The mo- tor may therefore only be used for devices that are not subject to this directive. *The Hall sensors in this motor are rated for ambient temperatures up to 150°C. The motor with Hall sensors is fully tested at 200°C in the final inspection. Nevertheless, the Hall sensors may temporarily fail below 200°C under certain conditions. Notice
