IEC TS 60034-31:2021

IEC TS 60034-31:2021 provides application guidelines for selecting energy-efficient motors, including use with variable speed applications, and is relevant where motor choice affects energy performance, system behavior, and long-term operating cost. For engineering teams and procurement specialists, IEC TS 60034-31:2021 supports more informed evaluation of motor options against the intended duty, control method, and installation context. As a technical document, it is useful when comparing equipment alternatives, preparing compliance files, or aligning selection criteria with documented energy-efficiency objectives.

IEC TS 60034-31:2021 standard overview

Rotating electrical machines - Part 31: Selection of energy-efficient motors including variable speed applications - Application guidelines focuses on practical guidance for choosing motors where efficiency and drive compatibility are part of the technical assessment. It is especially relevant to teams performing documented evaluation of electrical equipment, reviewing performance criteria, or validating whether a motor solution suits variable speed operation. The publication serves as a compliance reference that can support engineering documentation, technical review, and conformity assessment preparation.

Applications of IEC TS 60034-31:2021

IEC TS 60034-31:2021 is commonly used in motor specification, plant modernization, equipment procurement, and verification activities involving rotating electrical machines. It may support selection work for industrial drives, process equipment, pumps, fans, compressors, and other systems where variable speed control influences energy use and operating consistency. Laboratories, consultants, and internal engineering teams can also use it during technical validation, supplier comparison, and quality workflows that require a clear basis for documenting motor selection decisions.

Why IEC TS 60034-31:2021 matters

This technical guidance matters because motor selection decisions can affect efficiency, interoperability with variable speed drives, and overall system reliability. Using IEC TS 60034-31:2021 can help reduce risk in procurement and engineering review by providing a structured basis for comparison and technical assessment. It also supports more consistent testing workflows and conformity assessment preparation, especially where organizations need to show that chosen equipment aligns with operational requirements, energy objectives, and internal compliance practices.
