IEEE P1719/D56, Dec 2023

IEEE P1719/D56, Dec 2023 is a draft IEEE guide for evaluating stator cores of AC electric machines rated 1 MVA and higher. It focuses on the inspection, assessment, and technical review of stator core condition, helping engineers and asset owners judge performance and integrity in larger rotating machines. By addressing core evaluation in power and industrial equipment, IEEE P1719/D56, Dec 2023 supports more consistent decisions about maintenance, testing, and continued service.

IEEE P1719/D56, Dec 2023 overview

This draft guide is set within the technical area of electromagnetics and power applications, where stator core condition can affect machine losses, heating, and overall reliability. IEEE P1719/D56, Dec 2023 is relevant to AC electric machines at or above 1 MVA, where evaluation practices often need to be more structured and repeatable. The document is intended to guide judgment of core condition rather than define a one-size-fits-all design, making it useful for technical review and field assessment.

Typical use cases

IEEE P1719/D56, Dec 2023 is commonly used when checking stator cores in large motors, generators, and similar AC machines during commissioning, outage work, or refurbishment planning. It may support inspection workflows that look for physical damage, thermal concerns, or signs of core degradation before returning equipment to service. The guide is also useful in procurement and engineering review when comparing test results, documenting condition, or deciding whether further analysis or corrective action is needed for a machine rated 1 MVA and higher.

Why this standard matters

For large electric machines, stator core condition can influence operating efficiency, reliability, and maintenance cost. IEEE P1719/D56, Dec 2023 helps create a common basis for evaluating those cores, which can reduce uncertainty in testing and repair decisions. Using a recognized guide improves consistency across teams and sites, supports better compliance with internal engineering practices, and can lower the risk of overlooked defects. It is especially valuable when technical decisions must be documented and justified.
