¿El motor consume mucha corriente en vacío, aunque los datos del bobinado son correctos? ¿El motor se calienta con carga de forma inusual? Estas son preguntas comunes que pueden ser resueltas verificando la condición del núcleo del estator. En este webinario discutiremos cómo realizar la prueba de lazo en el núcleo de un estator y cómo analizar los resultados obtenidos, proporcionando información sobre los equipos utilizados, consejos para reparar el núcleo del estator y otras pruebas alternativas.

El seminario incluye:

  • Teoría de la prueba de lazo (“toroide”)
  • Procedimiento de prueba
  • Límites aceptables para las pérdidas y las temperaturas en el núcleo
  • Equipo asociado
  • Consejos para la reparación de núcleos dañados
