MT 9 - TC 2/MT 9

IEC TS 60034-25:2022 describes the performance characteristics of AC electrical machines for use on converter supplies. For electrical machines specifically designed for converter duty application design features are defined. It also specifies the interface parameters and interactions between the electrical machine and the converter including installation guidance as part of a power drive system, but except for the voltage at the power interface which is described in IEC TS 61800-8. This fourth edition of IEC TS 60034-25 cancels and replaces the third edition, This edition includes the following significant technical changes with respect to the previous edition:
a. The definitions of a converter capable motor and a converter duty motor are added.
b. Clause 18 modified to include the performance expectations of a converter capable motor.
c. Clause 8 modified to update shaft currents section.
d. Annex D added to define the derating requirements.

IEC TS 60034-25:2014 describes the performance characteristics of a.c. electrical machines for use on converter supplies. For electrical machines specifically designed for converter duty application design features are defined. It also specifies the interface parameters and interactions between the electrical machine and the converter including installation guidance as part of a power drive system, but except for the voltage at the power interface which is described in IEC 61800-8. The main technical changes with regard to the previous edition are as follows:
- merging of IEC TS 60034-17 into IEC TS 60034-25 adding a clause which now includes all specific requirements for standard non-definite purpose electric machines;
- removal of Annex C: Noise increments due to converter supply.

IEC 60050-212:2010 gives the general terminology used in discussing electrical insulating solids, liquids and gasses. This second edition cancels and replaces the first edition published in 1990. It constitutes a technical revision. It includes updated terms and definitions with respect to the previous edition. It has the status of a horizontal standard in accordance with IEC Guide 108.
