Why Use API 541? Standard specification that provides customized product Creates motor definitionDictates proposal preparationSimplifies proposal evaluationProvides for a reliable machine Utilizes comprehensive data sheets Important to everyone involved from manufacturer to userSauer May 2017Page 5

API 541 5th Edition - ScopeThis standard covers the minimum requirements for special purpose form-wound squirrel-cage induction motors 375kW (500 Horsepower) and larger for use in petroleum, chemical and other industry applications.Note 1: Special purpose machines typically have one or more of the following characteristics:1. Is in an application for which the equipment is designed for uninterrupted, continuous operation in critical service,and for which there is usually no installed spare equipment.2. Is larger than 2250 kW (3000 hp) for speeds 1800 RPM and below.3. Is rated 600 kW (800 hp) or greater for two-pole (3000 or 3600-RPM) machines of totally-enclosed construction, orrated 930 kW (1250 hp) or greater for two-pole machines of open or guarded construction (including machines withWP-I or WP-II type enclosures).4. Drives a high-inertia load (in excess of the load WK2 listed in NEMA MG 1 Part 20).5. Uses an adjustable speed drive as a source of power.6. Is an induction generator.7. Is a vertical machine rated 375 kW (500 hp) or greater.8. Operates in abnormally hostile environments.Sauer May 2017Page 6
