When there is a need for cleaning the contact surfaces of commutators and slip rings with brushes, emery cloth with aluminum oxide is NOT recommended, as conductive abrasive particles will cause arcing and damage to the surface. Many times, stone cleaning, garnet paper and machining are not a convenient, sufficient, or cost-effective option for machines as the priority is to keep the downtime to a minimum. This is when the carbon brush can be designed to clean up the contact surface.

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.

Sewage and wastewater treatment pumps are common machines repaired in EASA service centers. While both odor and biohazard are real problems, there are ways to deal with each, and service centers looking to broaden their repair market should not shy away from a profitable market because of the odor and biohazard. 

Las bombas de tratamiento de aguas residuales y residuales son máquinas habituales que se reparan en los centros de servicio de EASA. Si bien tanto el olor como el riesgo biológico son problemas reales, hay maneras de abordar cada uno de ellos, y los centros de servicio que buscan ampliar su mercado de reparación no deberían rehuir un mercado rentable debido al olor y el riesgo biológico.

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.

En este artículo, se profundizará en los motores de CA responsables de las funciones de inclinación y elevación de las apiladoras de troncos. Estos motores poseen características distintivas, incluido un rotor de alta resistencia.

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 video shows the proper way to lubricate the deep-groove, open ball bearing before assembling a horizontal induction motor.

This video shows the proper procedure for seating carbon brushes in a DC machine.

This video will walk you through how to check the relative polarity of DC machine interpoles and the armature and correct it if necessary using a simple interpole polarity test.

This video demonstrates the correct way to use an induction bearing heater to install an interference fit ball bearing on a machine shaft.

When working with DC machines, it’s not uncommon to find a customer who runs different products requiring a range of armature current. Unlike other conductors, where lower current is a good thing, carbon brushes are designed for a narrow range of current density. A unique aspect of carbon brush life is that brushes operating at a much lower current density than they are designed for do not last nearly as long as expected.

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.

Al trabajar con máquinas de CC, no es raro encontrar un cliente que fabrica diferentes productos que requieren un rango de corriente de armadura. A diferencia de otros conductores, donde una corriente más baja es algo bueno, las escobillas de carbón están diseñadas con poco margen de densidad de corriente.

The phase balance test is a simple yet effective method for diagnosing some problems with existing windings and for inspecting new windings before resin treatment. Including thermography enhances diagnostic capabilities, making it a valuable addition to the testing process.

La prueba de equilibrio de fases es un método simple y efectivo para diagnosticar algunos problemas en los devanados existentes y para inspeccionar devanados nuevos antes del tratamiento final. Incluir termografía mejora el diagnóstico, lo que es una adición valiosa para el proceso de prueba.

In addition to seal oil, some submersibles have an oil filled stator cavity. The oil in the stator cavity very efficiently transfers heat from the stator winding and core, and especially from the rotor, to the pump casing where convection carries it to the pumpage in which the pump is submerged. While the specifications for seal oil are fairly flexible, stator cavity oil has more constraints.

Have you ever thought about using a step counter on your employees in a test setting? This idea can provide valuable data to help you understand how much movement your workers must perform daily due to the current workshop layout. By analyzing this data, you can identify inefficiencies in the layout that may not be immediately obvious.

Además del aceite de sellado, algunas bombas sumergibles tienen una cavidad del estator llena de aceite. Este aceite transfiere de manera muy eficiente el calor desde el devanado y el núcleo del estator, y especialmente desde el rotor, hasta la carcasa de la bomba, donde la convección lo lleva al líquido de bombeo en el que está sumergida. Si bien las especificaciones para el aceite de sellado son bastante flexibles, el aceite de la cavidad del estator tiene más restricciones.

This presentation reviews procedures that explain how to identify unmarked leads of three-phase motors with one or two windings.

This article looks at the installation and removal of quick detachable (QD) and taper lock pulleys.

Pumps, compressors, fans and other types of mechanical movement are crucial to our industrial activities. Consequently, the health of these motors directly influences the operational reliability and longevity of the broader industrial ecosystem. Acknowledging this underscores the necessity for performing online health assessments of electric motors.

En este artículo discutiremos dos tipos de poleas: poleas de desmontaje rápido (QD) y poleas con bloqueo cónico y se proporcionarán instrucciones para instalar y desmontar ambos tipos.

This presentation focusses on critical close fit tolerances and certain surface finish specifications.

Hay una industria que ha estado reciclando silenciosamente desde antes del comienzo del siglo pasado. Así es: Más de 100 años de reciclaje. ¿De qué industria se trata? Es nuestra industria: La reparación de máquinas eléctricas.

There is one industry that has been quietly recycling since before the start of the previous century. That’s right – over 100 years of recycling. What industry is that? It’s our industry – electrical equipment repair.
