General-purpose Form-wound Squirrel Cage Induction Motors 250 Horsepower and Larger - First Edition
N STD 547
Annotation
This standard covers the requirements for form-wound induction motors for use in general-purpose petroleum, chemical and other industrial severe duty applications. These motors:
a. Are rated 250 hp (185 kW) through 3000 hp (2250 kW) for 4, 6 and 8 pole speeds.
b. Are rated less than 800 hp (600 kW) for two-pole (3000 RPM or 3600 RPM) motors of totally-enclosed construction.
c. Are rated less than 1250 hp (930 kW) for two-pole motors of WP II type enclosures.
d. Drive centrifugal loads.
e. Drive loads having inertia values within those listed in NEMA MG 1 Part 20.
f. Are not induction generators.
Note: Motors larger than that covered above and motors in other applications should be specified in accordance with API Std 541.
