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.

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.

Las bombas, compresores, ventiladores y otros tipos de movimientos mecánicos son cruciales para nuestras actividades industriales. En consecuencia, la salud de estos motores influye directamente en la confiabilidad operativa y la longevidad del ecosistema industrial más amplio. Reconocer esto resalta la necesidad de evaluar la salud de los motores eléctricos en operación. 

When a core loss test reveals localized hot spots, or visual inspection identifies physical damage, the ability to repair the damage in a cost-effective manner means the difference between repair or replacement.

Cuando la resonancia causa una vibración excesiva, es importante identificar la frecuencia natural y la forma modal de la vibración. Una simple prueba de impacto (bump test), realizada a máquina parada, es un buen primer paso para identificar la frecuencia natural.

When resonance does cause excessive vibration, it is important to identify the natural frequency and the mode shape of the vibration. A simple bump test, conducted with the machine not running, is a good first step in identifying the natural frequency.

Are you encountering high no-load current or high current with load? This presentation will look into the causes and cures.

This video explains how to check the ground insulation of an AC motor winding using the insulation resistance (IR) test.
