There are various applications for vertical motors, but most of them are mounted on vertical turbine pumps (VTPs). Vertical motors may be hollow shaft or solid shaft; the hollow shaft motors are used exclusively on VTPs and vibration is a common problem with these installations. The focus of this article will be on imbalance and 1x RPM vibration.

Los motores verticales son un elemento común en la mayoría de los centros de servicio adscritos a EASA y existen diversas aplicaciones para ellos, sin embargo la mayoría de ellos se montan en bombas de turbina vertical (VTP). La vibración es un problema común. Este artículo se centrará en el desbalanceo y la vibración a 1x RPM.

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.

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.

One of the main benefits of this presentation is to improve ability to “get it right the first time” to avoid the added cost and time of another rewind to correct errors.

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.

Cuando sea necesario limpiar las superficies de contacto de los colectores y anillos rozantes, NO se recomienda usar tela de esmeril con óxido de aluminio, ya que las partículas abrasivas conductoras pueden causar arcos eléctricos y dañar la superficie. Muchas veces, la limpieza con piedra, el papel granate (Garnett) y el mecanizado no son una opción conveniente, suficiente ni rentable para las máquinas, ya que la prioridad es minimizar el tiempo de parada. En este caso, la escobilla de carbón se puede diseñar para limpiar la superficie de contacto.
