摘要

Siemens Industry Inc. has introduced a new design concept for the low vibration version of its rugged SD100 IEEE841 motor. The frame, bearing housings, stator and rotor employ the company's most technologically advanced designs to surpass the vibration requirements of the IEEE Std 841-2009, which requires 3,600 rpm motors to operate with a maximum filtered vibration of .05 in./sec at twice speed or twice line frequency. Siemens test results of .033 in./sec have been recorded for the new design, exceeding the standard. The new motor is well suited for severe duty applications in petrochemical and paper processing, among others. Features include: rugged cast iron frame, bearing housings, fan cover and conduit box; double-drilled (8 mounting holes) feet for easy installation; 6-bolt bearing housings for improved stiffness; NEMA Premium or higher efficiencies to lower operating costs; Inpro/ Seal bearing isolators on both ends of the motor to protect bearings; and inverter-rated insulation system.
