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.

This presentation reviews procedures that explain how to identify unmarked leads of three-phase motors with one or two windings.

Learn how to effectively use EASA's live, ever-expanding online database of more than 250,000 windings.

This article explains in layman’s terms what electromechanical professionals refer to as circulating currents, why they exist in three-phase electric motors and to offer practical solutions.
