Es bien conocido por aquellos que trabajan con el almacenamiento de motores eléctricos que las filosofías y procedimientos de mantenimiento varían. La revisión minuciosa de la información de EASA y siete fabricantes de motores diferentes sobre el almacenamiento de motores reveló algunas diferencias y similitudes interesantes en la información disponible en cada una de las fuentes consultadas.

Varias fuentes comparten elementos comunes como el ambiente, la protección contra humedad, el mantenimiento de los rodamientos y la resistencia de aislamiento. Aquí, la finalidad de nuestro debate es describir algunas de las diferencias y ojalá dar a conocer algunos puntos a tener en cuenta cuando se crea un procedimiento de almacenamiento a largo plazo para los usuarios finales.
