GB/T 997-2022 Classification of types of construction,mounting arrangements and terminal box position (IM Code) for rotating electrical machines
Abstract
This document specifies the structural types, installation types, and the classification of the wiring box positions of rotating motors - IM code.
The two classification methods are defined as follows:
—— Code 1 (see Chapter 4): The alphanumeric code is suitable for motors with end-cover bearings and one shaft extension.
—— Code 2 (see Chapter 5): The all-numeric code is suitable for a wider range of motor types, including the motor types covered by Code 1.
Motor types not listed in Code 2 require a complete written description.
The relationship between Code 1 and Code 2 is described in Appendix A.
