Abstract

En isolert kjernetapp for bruk i kjernekonstruksjonen av minst én av en stator og en rotor i en dynamoelektrisk maskin bestemt for å passere gjennom hull i lamineringer i kjernekonstruksjonen. Den isolerte kjernetapp har et sentralt parti og et første lag av varmekrympbar rørformet isolasjon krympetilpasset på og dekkende minst det sentrale parti av kjernetappen som passerer gjennom lamineringene. En eller flere ytterligere lag av varmekrympbar rørformet isolasjon er krympetilpasset på minst ett parti av det første lag av isolasjon som passerer gjennom lamineringene. Disse andre lag tilveiebringer mekanisk beskyttelse for de underliggende lag av isolasjon mot brudd som skjer i den elektriske isolasjon når lamineringene og kjernetappene sammenstilles inn i kjernekonstruksjonen.
