Data verification and redesign of machines with form coil windings can be done in Motor Winding Workbench with the exception of rectangular conductor and insulation dimensioning. To address this need, a Form Coil Worksheet has been added to EASA’s online calculators.

La verificación de datos y el rediseño de máquinas con bobinados en pletina (solera) se puede realizar en Motor Winding Workbench, a excepción del dimensionamiento de conductores rectangulares y del aislamiento. Para cubrir esta necesidad, se ha añadido a las calculadoras en línea de EASA una hoja de cálculo para bobinas de pletina. 

Both the core loss and hot spot temperature MUST be considered when evaluating a core prior to rewind.

While there are mechanical concerns to consider as well, this article covers only the drying of the winding. The techniques listed here broadly cover stator windings, armatures, field poles, wound rotors and rotor poles.

El secado de devanados en campo presenta desafíos únicos en comparación con el secado en un centro de servicio.  Si bien también existen aspectos mecánicos que deben tenerse en cuenta, este artículo se centra exclusivamente en el secado del devanado. Las técnicas que se enumeran a continuación abarcan, en términos generales, los devanados de estator, las armaduras, las bobinas de campo, los rotores bobinados y los polos de un rotor.

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! 

This presentation covers what partial discharge is, how partial discharge damages insulation, and some testing methods.   

When equipment fails and customers wait, knowing exactly how to test each temperature-sensing device becomes critical. Don't let temperature accessories be your diagnostic blind spot.

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.
