The 2024 NEMA MG 00001 standard introduces key updates, including new Design BE and CE motors with defined locked-rotor current limits, Class N insulation for high-temperature use, and revised stall time requirements. It adds Super Premium efficiency levels aligned with IEC IE4, adopts IEC voltage/frequency variation guidelines, and expands duty ratings for variable load/speed motors.

La norma NEMA MG 00001 2024 introduce actualizaciones clave, incluyendo nuevos motores de Diseño BE y CE con límites de corriente de rotor bloqueado definidos, aislamiento Clase N para uso a alta temperatura y requisitos revisados ​​de tiempo de pérdida. Añade niveles de eficiencia Super Premium alineados con IEC IE4, adopta las directrices IEC sobre variación de voltaje/frecuencia y amplía las capacidades de servicio para motores de carga/velocidad variable.

The information in this article provides comparisons of key characteristics of IEC and NEMA motors to aid in evaluating the potential simplicity or complexity of the IEC to NEMA design conversion.

Being proactive on behalf of the repair industry, EASA created the best practice repair standard for the industry. This article looks back on this history of this important document.

Durante los 90, las normas gubernamentales para la eficiencia de los motores eléctricos fabricados generaron preocupaciones de que pudieran surgir regulaciones o normas para la reparación de motores eléctricos. Como representante de la industria de reparación de motores eléctricos, EASA respondió buscando el reconocimiento de su Práctica Recomendada para la Reparación como Norma Nacional Americana. Ser proactivo en la obtención de dicho reconocimiento significaría que, en nombre de la industria de la reparación, EASA crearía la norma de las mejores prácticas de reparación para la industria.

El propósito de IEEE 841-2021 es definir requisitos específicos que mejoren el rendimiento mecánico, el rendimiento eléctrico y la confiabilidad del motor. Vea lo que se ha hecho para actualizarlo con los últimos estándares.

The purpose of IEEE 841-2021 is to define specific requirements that improve the mechanical performance, electrical performance and reliability of the motor. See what has been done to bring it up to date with the latest standards

The procedure for aligning two rotating machines requires measuring their relative shaft positions and adjusting one or both machines. Until recently, though, how closely the shafts need to be aligned was an open question. That changed with the publication of American National Standards Institute/Acoustical Society of America (ANSI/ASA) standard 2.75-17.

This article explores the distinction between a controlled environment and a cleanroom, the requirements for both, and provides details to help you determine if you want to add a controlled environment or a cleanroom to your facility.

The US Department of Energy (DOE) has issued rulemaking on test procedures for small electric motors for more than a decade. The present “final rule,” effective February 3, 2021, is the culmination of those efforts.

This valuable publication explains the findings of a major study that analyzed the impact of repair/rewinding on the energy efficiency of Premium Efficiency/IE3 electric motors. This study was a follow up to a 2003 study.

This webinar covers the results and the technical details of the recently completed follow-up to the 2003 EASA/AEMT Rewind Study.

How are your marketing efforts related to the latest changes in the National Fire Protection Association's electrical safety standard, NFPA 70E® Standard for Electrical Safety in the Workplace? 
The NFPA 70E® has a specific purpose, and it never mentions marketing. After all, these are two entirely different subjects. Or are they?

ANSI/EASA AR100 is a must-have guide to the repair of rotating electrical machines. Its purpose is to establish recommended practices in each step of the rotating electrical apparatus rewinding and rebuilding processes.

What are the normal conditions for which a motor is designed? This is a question that does not often come up except when there is an issue with a motor application.

¿Cuáles son las condiciones normales para las que está diseñado un motor eléctrico? Esta es una pregunta que no surge muy a menudo, excepto cuando existe un problema con la aplicación.

This manual covers horizontal and vertical squirrel-cage induction motors in the 300 to 5,000 horsepower range, low- and medium-voltage. Most of the principles covered apply to other sizes as well. This manual focuses primarily on IEC motors and standards.

There are changes in the National Electrical Code that EASA members need to know about. View this webinar to learn:

• The background behind these changes
• The 2020 change impacting reconditioned motors
• How the changes will be interpreted
• What the changes mean for the electric motor service industry

The international Ex community (Ex equipment manufacturers, end users and regulators) have worked hard at providing standardization of technical requirements for Ex equipment and systems now reflected in a mature set of standards; work on standardizing the approaches to testing and certification is relatively young. The benefits of publishing international equipment standards can be overshadowed by the application of different testing and certification practices and systems. This can result in costly re-testing and re-certification as well as lost time-to-market for manufacturers and down time for plant operators. While Underwriters Laboratories (UL), the Canadian Standards Association (CSA) and Equipment and Protective Systems intended for use in Potentially Explosive Atmospheres (ATEX) Directive have been seen as a solution to a converging common approach, the question remains: "What about companies and organizations that operate globally?"
