Embodiment Construction

[0104] figure 1 The prior art is shown, namely the laminations of a lamination pack made of soft magnetic material 3 , which also has a magnetic field shielding 5 . The magnetic field shield 5 is stamped from laminations and filled with air or other gas. The figure also shows webs 7 which bring the laminations together and secure them. Furthermore, the figure shows the direction of rotation R, the center point M, the axis q as well as the axis d and the material channel 12 .

[0105] As long as the reference numbers described are present in the exemplary embodiments, they also apply to the subsequent figures and are not described again for reasons of clarity.

[0106] figure 2 A material layer 1 for a machine, in particular a reluctance machine, is shown. The material layer comprises a magnetic flux guiding region 9 and a magnetic flux blocking region 11 . The magnetic flux guiding region 9 has a magnetic material, in particular a soft magnetic material.

Abstract

The invention relates to a material layer (1) for a dynamoelectric rotary machine (6), said material layer (1) comprising magnetic-flux conductive regions (9) having a first material with a first magnetic permeability [mu]r > 50, and at least one flux non-conductive region (11) having a second material with a lower magnetic permeability [mu]r < 5 than the first magnetic permeability, wherein the first material and the second material are integrally joined. The invention further relates to a method for producing a material layer (1) of this type.

Description

technical field [0001] The invention relates to a material layer for a rotating electrical machine, wherein the material layer comprises a magnetic flux guiding region and at least one magnetic flux blocking region, the magnetic flux guiding region has a first material with a first magnetic permeability μr > 50, the magnetic flux blocking region has a second magnetic flux blocking region Two materials, the second material has a second magnetic permeability of μr<5 which is smaller than the first magnetic permeability. Background technique [0002] The stator and rotor are part of the magnetic circuit of a machine that can operate as both a motor and a generator. The stator and rotor are the working parts of the machine, also known as active parts, and until now were manufactured as stacks of laminations. [0003] Lamination packs consist of cut or stamped rolled large metal plates made of soft magnetic material. These laminations are then packaged into lamination pac...
