Embodiment Construction

[0014] specific implementation plan

[0015] One embodiment of the invention relates to a skew motor with a stator and / or a rotor comprising at least one layer of composite material, characterized in that the composite material has at least one layer of electrical steel strip as carrier and at least one polymer layer.

[0016] Motors can be divided into the following categories: First, synchronous motors: individually excited synchronous motors, permanent magnet excited synchronous motors, synchronous reluctance motors and cross-flow motors; secondly, asynchronous motors: rotating field motors with slip ring rotors or cage rotors . The mentioned electric motors can be implemented with or without skew in the stator and rotor.

[0017] According to the invention, electric motors are used in which the stator is continuously tilted, the rotor is continuously tilted and / or the rotor rotates in segments (in particular in the case of permanently excited synchronous machines). In ad...

Abstract

The present invention relates to an electric motor with slanted stator and / or rotor containing at least one layer of a composite material, characterized in that the composite material comprises at least one electric strip layer as carrier and at least one polymer layer. The invention also relates to the use of the composite material to reduce the acoustic emission in slanted electric motors, and to a method for reducing the acoustic emission in these electric motors on the basis of the use of the composite material.

Description

technical field [0001] The invention relates to an electric motor with a skewed stator and / or rotor comprising at least one layer of composite material, characterized in that the composite material has at least one layer of electrical steel strip as carrier and at least one polymer layer; the invention also relates to Use of composite materials to reduce acoustic emissions in skewed electric motors, and methods to reduce acoustic emissions in these electric motors based on the use of composite materials. [0002] The invention relates to all types of electric motors in which the stator is continuously skewed, the rotor is continuously skewed and the rotor rotates in segments (especially in the case of permanent magnet excited synchronous machines). Furthermore, a deflection of the stator pole shoes and of the rotor surface can be produced by continuously or segmentally varying stator or rotor lamination segments. In the following, all variants are referred to as "skew motors"...
