Scope
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.
