Occasions arise where original winding data is not available; it may have been recorded incorrectly, or a different service center may have stripped the core but not completed the repair. In those cases, the service center must come up with a new “bare core” winding design. Motor Winding Workbench has some specific features to address this need.

Por lo general, los datos del bobinado se registran al momento en que se retira el alambre del núcleo. Sin embargo, a veces estos no están disponibles, han sido anotados de forma incorrecta, u otro centro de servicio ha retirado el bobinado del núcleo sin llegar a completar la reparación. En tales situaciones, el centro de servicio debe efectuar un diseño nuevo del bobinado partiendo del «núcleo sin datos» y Workbench cuenta con las funciones específicas para cubrir esta necesidad.

This article provides practical rules of thumb for evaluating the performance and health of three-phase squirrel-cage induction motors in industrial environments. Rather than requiring detailed engineering calculations, these guidelines help maintenance professionals quickly identify operating conditions that may lead to reduced reliability, overheating, nuisance trips, or premature motor failures.

This article explains the key considerations when replacing a failed motor with one built to a different standard. As IEC motors become more common in North America, maintenance professionals increasingly face situations where an IEC motor may need to be replaced with a NEMA motor, or vice versa. While this is often possible, the two standards contain important differences that must be evaluated carefully to avoid performance, reliability, and installation problems.

This webinar goes through some data verification and redesign examples using the Motor Stats view within EASA’s AC Motor Verification & Redesign software to learn what it tells us and what it doesn’t tell us about our data.

The information in this article provides comparisons of key characteristics of IEC and NEMA motors to aid in evaluating the potential simplicity or complexity of the IEC to NEMA design conversion.

La información de este artículo proporciona comparaciones de las características clave de los motores IEC y NEMA para ayudar a evaluar la posible simplicidad o complejidad de la conversión de diseño IEC a NEMA.

This article looks at some of the import details for a proper concentric to lap winding conversion. It also shows how using the EASA Technical Manual, EASA's AC Motor Verification & Redesign Software, as well as the EASA AC Redesign manual, can help.

Este artículo analiza algunos de los detalles de importación para una conversión adecuada de devanado concéntrico a devanado por vuelta. También muestra cómo puede ayudar el uso del Manual técnico de EASA, el software de rediseño y verificación de motores de CA de EASA, así como el manual de Rediseño de motores AC de EASA.

Most EASA service centers encounter very few axial-flux machines. They are rare enough that it is worthwhile to describe what they are and how they differ from the typical radial-flux industrial motor or generator.
