A tilted or improperly sized oil standpipe can allow oil to migrate upward along the pipe’s wall when the motor is in operation, leading to leakage, loss of lubrication and potential bearing damage. This issue can be overlooked during assembly or inspection, but a few simple checks can prevent costly problems.

Concentric to lap winding conversions are common practice in many EASA service centers. For most stators, this change is feasible and can be made with little difficulty. In some cases, however, it can be quite challenging and result in undesired outcomes due to reduction in copper or insulation.

Las conversiones de devanados concéntricos a imbricados son una práctica común en muchos centros de servicio de EASA y en la mayoría de los estatores, este cambio es factible y se puede realizar sin dificultad. Sin embargo, en algunos casos, puede resultar muy complicado y generar resultados no deseados debido a la reducción del cobre o la pared de aislamiento.
