The typical customer has an expectation of sending in their equipment to a service center to get it repaired correctly. Whatever the process, service centers should capture the “As Received” information accurately. This article will point out some pitfalls that can be avoided by taking the right steps during the “As Received” process.

El cliente típico espera enviar su equipo a un centro de servicio para que sea reparado de manera correcta. Sea cual sea el proceso, los centros de servicio deben registrar la información del estado "a la entrada" con total precisión. Este artículo señalará algunos errores comunes que se pueden evitar si se adoptan las medidas adecuadas durante el proceso de recepción del equipo.

Right now, electric utilities across North America are spending money like never before – and that investment is driving one of the biggest infrastructure buildouts we’ve ever seen. But here’s the thing: behind every new substation, data center and transmission line is another part of the story – the people and companies, especially within EASA, that repair, rebuild and maintain the motors, generators, transformers and associated switchgear that keep it all running. That’s the electromechanical side of the business, and it’s about to get a lot busier.

Artificial intelligence has quickly become one of the most talked-about technologies across every industry, including the electromechanical world. Depending on who you listen to, AI is either going to replace engineers and technicians, or it is just another overhyped tech trend. As is often the case, the reality sits somewhere in the middle. 

Artificial intelligence is one of the most talked about technologies in industry right now, but how much of it is actually being used inside EASA member companies? To better understand this, the Emerging Technologies Committee recently surveyed the membership about AI adoption in service centers.

The repair/replace conversation should be built on facts, not feelings. Customers respect recommendations that are based on clear, technical, logical and economic reasoning.  A simple framework helps keep the discussion professional instead of emotional. 

When equipment fails and customers wait, knowing exactly how to test each temperature-sensing device becomes critical. Don't let temperature accessories be your diagnostic blind spot.

The purpose of this article is to provide some tips for working with unequal-turn (odd-turn), two-layer lap windings, with emphasis on how to sequence the coils within the group for optimum slot fill.

El propósito de este artículo es brindar consejos para trabajar con bobinados imbricados de dos capas con vueltas desiguales (impares), con énfasis en cómo secuenciar las bobinas dentro del grupo para obtener un llenado óptimo de las ranuras

For decades, digital visibility meant mastering search engine optimization. But it no longer tells the whole story. AI-driven search systems operate by new logic.

NEMA anunció la revisión de la Tabla 12-23 de la norma MG 00001-2024, Motores y Generadores.

NEMA issues revision to motor efficiencies table (MG 00001-2024, Motors and Generators, Table 12-23).

Spectrum analysis is the primary tool for analyzing vibration problems. Yet, a lot of useful information can be acquired by tracking the vibration characteristics as power is disconnected from the machine.

Simple diagnostic tests—such as bump tests and speed‑variation checks—can be used to identify resonance as the cause of high vibration in rotating machinery. By recognizing when vibration frequencies align with natural frequencies, technicians can diagnose resonance issues early and avoid unnecessary corrective actions.

Este artículo explica cómo pruebas diagnósticas simples —como las pruebas de impacto (bump tests) y las verificaciones mediante variación de velocidad— pueden utilizarse para identificar la resonancia como causa de alta vibración en maquinaria rotativa. Al reconocer cuándo las frecuencias de vibración coinciden con las frecuencias naturales, los técnicos pueden diagnosticar problemas de resonancia tempranamente y evitar acciones correctivas innecesarias.

Like many EASA member service centers, Good Fruit Electric, LLC has learned that growth and sustainability depend on one thing: finding good people and helping them become productive quickly. Over the years, we’ve refined how we recruit and train new team members, but the process became far more effective when EASA introduced its learning management system.

Emotional intelligence is simply the ability to recognize, understand and manage your own emotions— and to recognize and respond to the emotions of others. When leaders grasp this side of their teams, performance improves—but more importantly, people grow. They become problem-solvers instead of task-doers. They become the next generation of leaders.

This webinar recording shares practical solutions for mechanics and winders to overcome common challenges and streamline their daily work.

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.

Many service centers are unable to perform full-load testing of large DC machines. The good news is that there are specific tests that can be performed on a DC motor to verify the integrity of windings, the correct relative polarity of armature to interpoles, and proper running performance. This article explains specific tests that can help ensure a motor operates properly when the motor is installed. 

Does your electric motor service center have prescribed standard operating procedures? When we hire a new team member, we load them up with policy, safety and procedural manuals, often including resources like ANSI/ EASA Standard AR100-2020. Yet, many service center owners and managers have a disconnect when it comes to formal skill development programs.

The purpose of this article is to explain the basis and application of rules used to “estimate” fan performance for a fan installed in a duct system moving air when the speed of the fan is changed.

Muchos centros de servicio no pueden realizar pruebas a plena carga en máquinas de corriente continua grandes, sin embargo, la buena noticia es que existen pruebas específicas que permiten verificar la integridad de los devanados, la polaridad relativa correcta entre la armadura y los interpolos, y el adecuado funcionamiento del motor. Este artículo explica pruebas específicas que pueden ayudar a garantizar que el motor funcione correctamente una vez instalado.

El propósito de este artículo es explicar los fundamentos y la aplicación de las reglas utilizadas para estimar el rendimiento de un ventilador instalado en un sistema de conductos que mueve aire al variar su velocidad. Con un conocimiento básico de estas reglas, es posible calcular rápidamente el rendimiento de un ventilador para diversas condiciones de velocidad.

La norma ANSI/EASA AR100 es una guía indispensable para la reparación de máquinas eléctricas rotativas. Su objetivo es establecer las prácticas recomendadas en cada etapa de los procesos de rebobinado y reconstrucción de aparatos eléctricos rotativos.

This presentation covers the important details for a properly converting a 3 phase winding from concentric to lap.

Identificar los cables sin marcar en los motores trifásicos es una tarea habitual para los técnicos de los centros de servicio. Este artículo presenta un método para asignar números a los cables de una máquina de 12 cables con los terminales sin marcar.

En el mundo de la maquinaria rotativa, términos como balanceo, holgura y alineación son habituales para ingenieros y técnicos. Pero hay un concepto que a menudo se esconde a simple vista, crucial para el rendimiento, la longevidad y la seguridad: la alineación del centro magnético.

No importa donde opere en el mundo, la respuesta más común a los desafíos parece ser redactar una nueva norma, directriz o marco regulatorio. El resultado suele ser un sistema de calidad que se convierte en una montaña de documentos, procedimientos y procesos, cada uno concebido para garantizar la calidad, pero que en conjunto amenaza con agobiar tanto a los tall-eres como a los ingenieros.

Identifying unmarked leads in three-phase motors is a common task for service center technicians. This article provides one way to assign lead numbers for a 12-lead machine with unmarked leads.
