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.
