Specialty Motors per API 541 4th Edition & API 547 Specifications
The highly demanding process industries, from oil production and refining to chemical processing and power generation, have adopted two rigorous standards set forth by the American Petroleum Institute for motor reliability and performance. API 541 - 4th Edition is for the most critical special purpose motors and API 547 is for severe-duty general purpose motors. No one meets these demanding standards with fewer comments or exceptions than Siemens.
Consult Siemens for a complete list of clarifications, exceptions, and bills of material that may apply. Motors bulit to API541 3rd Edition are also available upon request.
As of January 31, 2011, the Norwood, OH facility can offer motors per API 547 specification bearing the Official API Monogram®.
(NOTE: The use of the API Monogram by Siemens is pursuant to License # 547-0004 and is limited to the API product specifications shown. The use of the API Monogram does not constitute approval or endorsement of these products by the American Petroleum Institute.)
