Siemens Industry Inc. recently introduced a completely new design concept for the low vibration version of its rugged SD100 IEEE841 motor. The frame, bearing housings, stator and rotor employ technologically advanced designs to surpass the demanding vibration requirements of the IEEE Standard 841-2009.
The IEEE Std 841-2009 requires 3,600 rpm motors to operate with a maximum filtered vibration of .05 inch/second at twice speed or twice line frequency. This specification is particularly difficult to meet in the horizontal plane. Test results of .033 inches/second have been recorded, demonstrating the new low vibration motor not only meets the standard but exceeds it.
The new low vibration SD100 IEEE841 motor is well suited for a wide variety of severe duty applications in industries, such as petrochemical and paper processing. 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
- Inverter-rated insulation system
To provide users a variety of application options, the motors are available in three configurations: stock, modifiable through Siemens’ unique QuikMOD program, or custom-built to meet specific customer requirements.
