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.

Application
Notice
General – extreme temperature applications – vibration tested according to MIL-STD810F/ Jan2000 Fig. 514.5C-10 – operation in oil and high pressure (only minimal lubrication, therefore use under rated ambient conditions is not suggested) Oil & Gas Industry – oil, gas and geothermal wells
This motor contains leaded solder. It therefore does not fulfill the requirements for the permitted maximum con- centration of hazardous substances in accordance with the EC directive 2011/65/EC (RoHS) for all applications. The motor may therefore only be used for devices that are not subject to this directive. Reference medium: Shell Tellus oil T32 Operation in oil of different viscosity will affect the motor data. *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.
