NEMA Electric Motors
- Choose from lightweight aluminum NEMA motor versions
- For versatile general-purpose applications and
- heavy-duty cast iron NEMA motors for demanding industrial use.
NEMA Electric Motors, which are predominantly used in North America depending on regional standards and regulations, are designed for a wide range of industrial drive applications – from pumps, compressors and fans to conveyors, machine tools, petrochemical plants and other general-purpose three-phase applications.
They provide dependable performance for standard industrial duties as well as demanding operating environments.
NEMA Aluminum Motors are a practical choice for general-purpose industrial applications where reliable operation, flexible use and efficient integration into machinery are required. Typical applications include pumps, compressors, fans, conveyors, machine tools, petrochemical plants and other three-phase general-purpose applications.
NEMA Cast Iron Motors are built for demanding industrial environments and applications requiring a robust motor construction. The motor series features a NEMA Premium Energy Efficiency Design and is EISA regulation compliant.
For applications requiring enhanced mechanical strength and long-term reliability, NEMA cast iron motors provide a robust configuration with heavy-duty cast iron fan cover, double lip shaft seal protection, tropicalized VPI lap-wound Class H stator, rubber shaft slinger for vertical application and oversized bearings.
The motors are suitable for conveyors, gear reducers and applications requiring Design C torque.
Certain versions are Class 1, Div 2, Groups A, B, C and D certified.
Your benefits
NEMA Premium Energy Efficiency Design and EISA regulation compliance support energy-conscious motor selection for industrial applications.
MG1 Part 31 compliance for VFD use with 15:1 constant torque capability supports applications where variable speed operation is required.
Multi-mount frame design up to 320T, F1/F2/F0 configurations, interchangeable C and D flanges and a 90° rotatable conduit box help adapt the motor to different machine layouts.
