IE3 Severe Duty Motors

Categories: , Tag:


XSD Ultra 841 IEC technology meets or exceeds IE3/NEMA Premium nominal efficiencies and exceeds all IEC/NEMA Premium minimum guaranteed efficiencies. Each motor comes with its own test report demonstrating performance compliant with the IEEE 841 specification, but with IEC construction and designs. ​ A five-year warranty comes standard with every XSD Ultra 841 IEC motor (60 months operational/66 months maximum from shipment). ​

Overall vibration is 1.4 mm/sec (0.55 inches per second) vs 0.08 inches (0.06 for 8 pole) per second per IEEE 841. This helps to extend the life of the motor and the connected equipment. ​ Total shaft runout is 0.025 mm (0.001”) for shaft diameters up to 41 mm and 0.038 mm (0.0015”) for shaft diameters greater than 41 mm for ball bearing machines. ​ GEGARD insulation systems feature Class H insulation materials. This system increases motor protection against IGBT drive voltage spikes which exceed NEMA MG1-31 standards.
