NEMA 3 phase induction motors

Product catalog summary
Introduction
The document focuses on NEMA three-phase induction motors with cast-iron construction, emphasizing standardization and specifications. It highlights the role of the International Electrotechnical Commission (IEC) and its member countries, including the USA and Italy, in setting global standards for the electric field sector. Major institutes in the USA, such as ANSI, ASTM, IEEE, NEMA, and UL, are also discussed for their contributions to these standards.
NEMA Standards
NEMA is a national association that promotes cooperation between electric equipment manufacturers and users. It provides comprehensive publications for electric machines, including MG1 (Motors and Generators), MG2 (Construction Safety Standards), MG3 (Sound Level for Electric Machines), MG10 (Guide for Selection and Use of Electric Motors), and MG13 (Power rating/size correlation for Electric Motors). MG1 serves as a guide for standard motor design, covering definitions, final marking, dielectric strength test, dimensions, tolerances, construction types, power ratings, and application data.
ISGEV S.p.A.
ISGEV S.p.A. has been designing and constructing electric motors since 1948, known for its reliable, high-quality motors. The company adheres to ISO 9001:2000 standards, ensuring quality and customer satisfaction, and has expanded its market presence to Europe and America.
Electric Motor Warranty
I.S.G.E.V. S.p.A. guarantees the quality and construction of its motors, offering repair or replacement for defects in workmanship or assembly within a 12-month warranty period. The warranty excludes defects caused by natural wear, customer inexperience, or misuse beyond rated performance.
NEMA Motor Construction
The document details NEMA construction forms, divided into floor, wall, and ceiling mounted groups. It describes the standard terminal box with IP55 protection, upgradeable to IP56, and the use of NPT connectors for cable connections.
Bearings and Technical Specifications
Grease-lubricated ball bearings are used for all axis heights, with options for 2RS or C3 clearance bearings. Detailed tables provide motor types, power, speed, efficiency, current, torque, and moment of inertia for various pole configurations (2, 4, 6, and 8 poles) at 460V and 60Hz.
Conformity and Construction Forms
The document compares NEMA motor sizes with IEC standards, providing a table of construction forms and frame sizes for different power ratings.
Overview
The document provides technical specifications and construction details for NEMA three-phase induction motors, including brake motors, explosion-proof motors, and high-speed motors. It includes dimensional tolerances, construction forms, and overall dimensions.
Specifications
Detailed specifications for different motor frames are listed, including dimension tolerances for U, AK, and D dimensions. For example, U dimension tolerance is up to 34.925 from 0 to -0.013, and over, from 0 to -0.025. AK dimension tolerance is up to frame 286C from 0 to -0.076, and over, from 0 to -0.127.
Construction Forms
The motors are available in various construction forms, including those with flanges with threaded holes (NEMA C) and those with feet and flanges with threaded holes (NEMA TC). Specific frames come with lifting eyebolts or flanges with 8 holes.
Dimensional Data
Extensive dimensional data in millimeters is provided for various motor components, including shaft projections and overall dimensions, critical for ensuring compatibility and proper installation.
Product Variants
The document mentions different motor versions, such as cast iron and aluminum, and highlights special types like servo ventilated motors, extreme temperature motors, and motors with integrated inverters.
Manufacturer Information
ISGEV S.p.a., located in Arzignano, Italy, is the manufacturer. Contact details, including telephone, fax, and email, are provided for further inquiries.
