Staplingsmetoderna omfattar bland annat interleaved- och butt-lap-konfigurationer. Interfolierade staplar minskar kopplingsmotst\u00e5ndet, vilket f\u00f6rb\u00e4ttrar fl\u00f6desf\u00f6rdelningen. Svetsning eller fastsp\u00e4nning s\u00e4krar lamellerna mot vibrationer. Gl\u00f6dgning efter stansning avlastar mekaniska sp\u00e4nningar. Detta steg \u00e5terst\u00e4ller den magnetiska mjukheten och minskar koercitivkraften. Medarbetare vid monteringslinjen inspekterar varje k\u00e4rna med avseende p\u00e5 planhet och isolationsmotst\u00e5nd.

En f\u00f6rb\u00e4ttring av k\u00e4rnf\u00f6rlusten med 1% kan spara tusentals dollar per \u00e5r per stor motor. Livscykelkostnadsanalys \u00e4r numera standard vid ink\u00f6p. Ink\u00f6pschefer f\u00f6ljer r\u00e5varupriser och tillg\u00e4nglighet. Priserna p\u00e5 kiselst\u00e5l fluktuerar i takt med r\u00e5varumarknaderna.
