Abstract

An electric motor with a beveled stator and/or rotor has at least one layer of a composite material. The composite material has at least one electrical steel strip layer as carrier and at least one polymer layer. The composite material can be used for reducing acoustic emission in beveled electric motors. A method of reducing acoustic emission in these electric motors is based on the use of the composite material.
