The invention relates to a non-grain-oriented electrical steel strip or sheet, in particular for electrical applications, an electrical component produced from such an electrical steel strip or sheet, a process for producing an electrical steel strip or sheet and the use of such an electrical steel strip or sheet in components for electrical applications.

Electrical steel strip that can be but doesn't have to be reannealed

The present disclosure provides a non-grain-oriented electrical steel strip which can be used in electric machines such as electric motors and generators. In examples, the non-grain oriented electrical steel strip can be used as a stator having good magnetic properties and as a rotor having good mechanical properties. A reference heat treatment performed subsequent to an initial final heat treatment makes it possible to obtain improved magnetic properties.

A composite material, especially for use in a stator stack and/or rotor stack is disclosed. The composite material includes a first and a second electrical steel strip layer and a polymeric layer arranged in between, wherein the polymeric layer consists of a crosslinked acrylate-based copolymer of high molecular weight and has a layer thickness in the range from 3 to 20 &#x3bc;m.
