IEC 60034-7:2020 specifies the IM Code, a classification of types of construction, mounting arrangements and the terminal box position of rotating electrical machines. Two systems of classification are provided as follows:
- Code I: An alpha-numeric designation applicable to machines with end-shield bearing(s) and only one shaft extension
- Code II: An all-numeric designation applicable to a wider range of types of machines including types covered by Code I.

- new subclause on marking of shaft inclination or declination.
