Siemens low vibration motor exceeds IEEE STD 841-2009

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.  Separately, Siemens 1FK7 servomotors are now available in three weeks.

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.

IEEE Std 841-2009 requires 3,600 rpm motors to operate with a maximum filtered vibration of .05 in./sec at twice speed or twice line frequency. This standard is particularly difficult to meet in the horizontal plane. Siemens test results of .033 in./sec have been recorded for the new design, exceeding the standard.

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:





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.

The Drive Technologies (DT) division of Siemens Industry, Inc. supplies products and services for production machinery and machine tools. DT’s integrated electrical and mechanical technologies cover the entire drive train, and include standard products as well as industry-specific control and drive solutions for metal forming, printing and electronic manufacturing. DT also provides solutions for the glass, wood, plastics, ceramics, textiles, packaging equipment and crane system industries, as well as mechatronics support to online services for Web-based fault management and preventive maintenance.

Separately, Siemens Industry announced a new service for its line of 1FK7 servomotors . Using a configurable options menu to build exactly the motor required, customers in the U.S. market can now place an order and have it drop-shipped in three weeks. According to Arun Jain, general manager, Siemens Motion Control Business, "We have made the commitment to significantly shorten servomotor delivery times…. We have devised and implemented an entirely new protocol for motor manufacturing and production at our factories."

This new service applies to all compact (CT) and high-dynamic (HD) servomotors in the 1FK7 family. With a total of 6,150 option pairings and 18 color choices, servomotors in the 1FK7 family can be configured to 110,700 possible designs. Options include stall torque and RPM rating, encoder style and bit resolution, holding brake functionality, shaft style, IP rating, AC line supply voltage and electronic nameplate recognition via Drive-Cliq. 1FK7 geared motor options are not included in this program. With the Simotion motion controller and Sinamics S drive system stocked in the United States, Siemens can now supply complete motion control systems with three weeks lead time.
