For service professionals working with large electric motors and generators, machines with voltage ratings 5 kV and higher can be vulnerable to invisible threats of partial discharge (PD). Corona and PD activity have long been a challenge to detect before failure occurs. Traditionally, detecting these issues required indirect methods like radio interference voltage (RIV) testing, ultrasonic detection or offline insulation tests. But recent advances in partial discharge imaging—sometimes called corona cameras—are giving engineers and technicians a powerful new tool: the ability to see electrical discharge activity directly and in real time. 

As a small business owner employing skilled trade workers who are aging out of the workforce, sustainability is not just about the natural or political environment outside of our walls; it is increasingly becoming challenging in terms of sustaining the capabilities that our customers have come to expect from us.

As our company has grown, we have had to learn to trust others to get things done in a way that is consistent with how you would want them done. Here is how we chose to attack the trust issue and some of the lessons learned along the way.

Para los profesionales que trabajan con grandes motores y generadores eléctricos, las máquinas con tensiones nominales de 5 kV o superiores pueden ser vulnerables a amenazas invisibles de descargas parciales (DP). Detectar la actividad corona y las DP antes de que se produzca un fallo ha sido un desafío durante mucho tiempo. Tradicionalmente, detectar estos problemas requería métodos indirectos como pruebas de voltaje de radio interferencia (RIV), detección ultrasónica o pruebas de aislamiento a máquina parada. Sin embargo, los recientes avances en imágenes de descargas parciales, a veces llamadas cámaras corona, brindan a ingenieros y técnicos una nueva y poderosa herramienta: la capacidad de ver la actividad de descargas eléctricas directamente y en tiempo real.

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.

Managing through this polarizing political climate doesn’t mean that you must choose sides, but we do have to motor on. I have found three tips that help me in my business life.

This article highlights how motor repair service centers can support sustainability goals by documenting carbon offsets from motor upcycling. Rewinding motors typically reuses or recycles over 90% of materials, significantly reducing Scope 3 emissions. By leveraging EPA and transportation emission data, centers can provide science-based reports to clients aiming to meet environmental targets. This approach positions service centers as valuable partners in the circular economy and appeals to sustainability-conscious customers.

While robotic systems are advancing rapidly, their ability to replicate the complex, highly dexterous tasks performed by skilled craftworkers like motor winders, manual machinists and mechanics, especially in bespoke electric motor repair, is still significantly limited. Expert human judgment, adaptability and fine motor skills are not easily replicated by robots today, particularly in nuanced troubleshooting, diagnostics and precise manual repairs.

Este artículo destaca cómo los centros de servicio de reparación de motores pueden apoyar los objetivos de sostenibilidad mediante la documentación de las compensaciones de carbono del reciclaje de motores. El rebobinado de motores suele reutilizar o reciclar más del 90 % de los materiales, lo que reduce significativamente las emisiones de Alcance 3. Al aprovechar los datos de emisiones de la EPA y del transporte, los centros pueden proporcionar informes con base científica a los clientes que buscan cumplir los objetivos ambientales. Este enfoque posiciona a los centros de servicio como socios valiosos en la economía circular y atrae a clientes conscientes de la sostenibilidad.

Large Language Models (LLMs), powered by artificial intelligence (AI), can process and generate human-like text, making them invaluable for a variety of applications, including technical support, documentation, and troubleshooting. Just remember, these tools can be prone to error and when unrealistic or poor prompts are used.

Employee recruitment, retention and succession are all areas that are challenging and infinitely important to business and personal success. Increased employee engagement translates into enhanced quality outcomes and generally positive working conditions. So, how do we get there?

Revamping your employee reward system to shift away from a standardized approach to a more personalized model that offers a variety of options can make a big difference in engagement.

En el campo de la tecnología electromecánica, en evolución rápida, es crucial estar al día con las últimas herramientas y metodologías. Una de estas herramientas que ha cobrado gran relevancia es el Modelo de Lenguaje Grande (LLM). Estos modelos, impulsados por inteligencia artificial (IA), pueden procesar y generar texto con una calidad similar a la humana, lo que los hace invaluables para diversas aplicaciones, como soporte técnico, documentación y resolución de problemas.

This webinar goes through some data verification and redesign examples using the Motor Stats view within EASA’s AC Motor Verification & Redesign software to learn what it tells us and what it doesn’t tell us about our data.

Horizontal and vertical motors have uniquely different requirements for endplay, while sleeve bearing machines bring their own challenges. This presentation examines those differences.

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.

La información de este artículo proporciona comparaciones de las características clave de los motores IEC y NEMA para ayudar a evaluar la posible simplicidad o complejidad de la conversión de diseño IEC a NEMA.

This presentation 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.

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.
