The presentation portion of the webinar will last about 45 minutes, followed by about 15 minutes of questions and answers.

The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.

Identificar los cables no marcados en los motores trifásicos es una tarea común para los técnicos de los centros de servicio.

Para bobinados con 6 cables, vea el artículo de Chuck Yung publicado en la revista Currents en mayo de 2008: “Identifying Unmarked Leads of 6-Lead Motors With 1 or 2 Windings.” y para devanados con 9 cables, vea el artículo de Tom Bishop publicado en la revista Currents en abril de 2011: “Identifying 9 unmarked leads of three-phase motors.”

Este artículo explica una forma de numerar los cables en máquinas con 12 cables de salida, con devanados configurados como lo muestra la Figura 1. Usar 12 cables de salida permite a los fabricantes ofrecer múltiples opciones de voltaje y diferentes métodos de arranque con el mismo devanado. Sin embargo, si faltan algunas o todas las marcas de los cables, asignarles marcas válidas puede resultar bastante complicado. Si bien el procedimiento que se describe en este artículo funciona correctamente, requiere equipo especializado y al menos un desmontaje parcial de la máquina.
