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.

The impeller is the primary mass component on most pump rotors. Impeller balancing is an important component of pump repair. Proper balancing procedures will ensure the repaired pump will operate with a minimum of vibration.

The video provides a comprehensive guide on performing a single-phase rotor test on a three-phase squirrel cage motor to check for open rotor bars.

From the manufacturer’s perspective, a random-wound, 2300-volt motor represents a substantial reduction in manufacturing cost. For the service center, the challenge is to successfully rewind them while providing a reliable repair. Here are some techniques which will enhance your success rate.

Modern testing devices now have more capability than ever. Modern test equipment has gained multi-function testing capability. They even package the tests into colorful professional reports. With that being said, do we still need single function equipment to accurately diagnose and perform high quality inspections on electromechanical equipment?
