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.

An important element of the Reference Motor database is that all motor data includes the motor manufacturer name. The manufacturer name adds authenticity and helps members understand the source of the data.

When rewinding a typical three-phase motor, an experienced motor winder can usually identify the winding pattern quickly. However, there are also motors where anticipating a repeating pattern can get a repair center in trouble.

The new Motor Winding Workbench is now live and replaces EASA’s Motor Winding Database and the AC Motor Verification & Redesign program (Version 4). Visit workbench.easa.com (log in required) to access the new app that is included FREE as part of your EASA membership! 

The purpose of this article is to provide some tips for working with unequal-turn (odd-turn), two-layer lap windings, with emphasis on how to sequence the coils within the group for optimum slot fill.

ANSI/EASA AR100 is a must-have guide to the repair of rotating electrical machines. Its purpose is to establish recommended practices in each step of the rotating electrical apparatus rewinding and rebuilding processes.

La norma ANSI/EASA AR100 es una guía indispensable para la reparación de máquinas eléctricas rotativas. Su objetivo es establecer las prácticas recomendadas en cada etapa de los procesos de rebobinado y reconstrucción de aparatos eléctricos rotativos.

This presentation covers the important details for a properly converting a 3 phase winding from concentric to lap.

Identificar los cables sin marcar en los motores trifásicos es una tarea habitual para los técnicos de los centros de servicio. Este artículo presenta un método para asignar números a los cables de una máquina de 12 cables con los terminales sin marcar.

Identifying unmarked leads in three-phase motors is a common task for service center technicians. This article provides one way to assign lead numbers for a 12-lead machine with unmarked leads.
