Cuando sus procesos pueden facilitarlo y para rebajar costos de fabricación, los fabricantes casi siempre emplean en los estatores trifásicos de alambre redondo, bobinados concéntricos insertados con máquinas. Muchos centros de servicio también pueden rebobinar bobinados concéntricos, pero la práctica más común es la de utilizar bobinados excéntricos de doble capa. Para los estatores con bobinas pre-formadas, los fabricantes y los centros de servicio utilizan la mayoría de las veces, bobinados excéntricos de doble capa.

La finalidad de este artículo es proporcionar algunos consejos para trabajar con bobinados con espiras diferentes (impares) o con bobinados excéntricos de doble capa donde el número de espiras por ranura es un número impar (Ej. 3,5,7,9…n). En estos casos, los lados superior e inferior de la bobina deben tener un número de espiras diferente.
