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.
A Repeatable Method for Documenting Complex Three-Phase Windings
Article
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.

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.

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.
