IEC 60034-7:1992/AMD1:2000 Overview

IEC 60034-7:1992 Amendment 1 (2000) addresses the classification of rotating electrical machines by defining the International Mounting (IM) Code. It standardizes the types of construction, mounting arrangements, and terminal box positions for these machines. This amendment updates the original 1992 standard, offering clarifications and new coding rules to enhance uniformity in machine designation globally.

The IM Code enables manufacturers, engineers, and users to identify and specify mounting types and terminal box locations clearly, facilitating interoperability, installation, and maintenance of rotating electrical machines.

Key Topics in IEC 60034-7 Amendment 1

  • Classification of Construction Types:
    The standard categorizes machines based on shaft orientation:

    • Horizontal shaft machines (denoted as IM B...)
    • Vertical shaft machines (denoted as IM V...)
  • Mounting Arrangements:
    Defines how machines are mounted using feet, flanges, or other supports, with standardized codes describing each mounting configuration.
    For example:

    • IM V15: Vertical shaft machine with feet and a flange on the D-end, feet positioned downward with back access.
    • IM V17: Vertical shaft machine with flange but no rear access.
  • Terminal Box Positioning:
    A key update in Amendment 1 is the terminal box location coding system. The position of the terminal box is denoted by a letter appended to the mounting code. The coding rules specify how to view the machine (usually from the D-end) to determine the terminal box location.
    Location codes include:

    • R = Right (3 o’clock)
    • B = Bottom (6 o’clock)
    • L = Left (9 o’clock)
    • T = Top (12 o’clock)
    • None = Unspecified
  • Designation Examples:
    Amendment 1 introduces guidelines for designating machines with combined codes for shaft orientation, mounting, and terminal box position to ensure consistency across technical documents and catalogs.

  • Alignment with Previous Codes:
    The amendment also provides updated tables correlating the new IM Code with previous code systems, ensuring backward compatibility and aiding transition.

Applications of IEC 60034-7 Amendment 1

This amendment is essential for industries and professionals involved with rotating electrical machines, including motors and generators, covering:

  • Manufacturing:
    Ensures that machine producers classify and mark their products accurately for mounting and terminal arrangements.

  • Engineering Design and Installation:
    Helps engineers select machines compatible with mounting conditions and connector access points, reducing installation errors.

  • Maintenance and Service:
    Standardized terminal box positioning simplifies troubleshooting and servicing by defining consistent access points.

  • Procurement and Specification:
    Provides clear, internationally recognized designation methods for requesting and supplying rotating machines matching specific mounting and terminal box requirements.

Related Standards

  • IEC 60034 series:
    This amendment is part seven of the IEC 60034 series that addresses various aspects of rotating electrical machines including ratings, test methods, and performance requirements.

  • IEC 60529:
    Relates to protection degrees (IP codes), often used alongside mounting classifications for environmental considerations.

  • ISO 9001:
    Quality management systems that may incorporate IEC standards like 60034-7 to ensure product conformity and traceability.
