IEC 60034-26:2006/COR1:2014 is a corrigendum to the parent document IEC 60034-26:2006, correcting the technical record for Rotating electrical machines - Part 26: Effects of unbalanced voltages on the performance of three-phase cage induction motors. For engineering teams, laboratories, and procurement specialists, it supports accurate document control when evaluating motor performance under unbalanced supply conditions. As a supporting reference rather than a standalone technical specification, it is most useful where technical review, conformity assessment, and compliance workflows depend on the exact wording of the parent document.

Purpose of IEC 60034-26:2006/COR1:2014

The purpose of IEC 60034-26:2006/COR1:2014 is to amend and clarify the published guidance on how unbalanced voltages can affect three-phase cage induction motors. In practice, this kind of corrigendum helps maintain technical accuracy in design verification, test planning, and documented evaluation of motor performance. It is relevant to organizations that rely on the parent reference for operational consistency, risk management, and technical validation of rotating electrical machines in compliance-oriented engineering workflows.

Compliance applications of IEC 60034-26:2006/COR1:2014

IEC 60034-26:2006/COR1:2014 is commonly used when reviewing motor-related documentation, interpreting performance expectations, or aligning testing workflows with the corrected text of the parent document. It may be consulted by manufacturers, testing laboratories, and asset owners involved in product evaluation, laboratory evaluation, or procurement checks for three-phase cage induction motors. In regulated or quality-driven environments, it can support clearer engineering documentation and reduce ambiguity during technical assessment and conformity assessment preparation.

Benefits of IEC 60034-26:2006/COR1:2014

Using IEC 60034-26:2006/COR1:2014 helps organizations work from the corrected technical reference when assessing the effects of voltage unbalance on motor performance. That can improve testing consistency, reduce interpretation errors, and strengthen quality assurance across engineering and compliance workflows. It also supports safer decision-making by keeping conformity assessment and procurement review aligned with the published correction to the parent document. For teams managing electrical equipment documentation, this helps preserve technical integrity and reduce avoidable compliance risk.
