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?

Desde la perspectiva del fabricante, un motor de 2300 voltios con bobinado aleatorio representa una reducción sustancial en el costo de fabricación. Para el centro de servicio, el reto es rebobinarlos con éxito y ofrecer una reparación confiable. Aquí hay algunas técnicas que mejorarán su tasa de éxito.

Los dispositivos de prueba modernos cuentan con más capacidades que nunca.  Los equipos de prueba modernos también han adquirido la capacidad de realizar pruebas multifunción. Incluso compilan el resultado de las pruebas en informes profesionales a todo color. Dicho esto, ¿seguimos necesitando equipos monofunción para diagnosticar con precisión y realizar inspecciones de alta calidad en equipos electromecánicos?

This presentation stresses the importance of taking accurate winding data and explains and emphasizes the consequences of inaccurate data. 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.
