Abstract

An electrotechnical device for an aircraft includes a housing having a surface and a magnetic circuit formed by a stack of laminated sheets and composed of a yoke. The yoke is fixed on the surface of the housing by means of a thermal interface and has a surface. At least one low-frequency coil component is attached to at least part of the surface of the yoke by attachment means.

Claims (17)

1 . An electrotechnical device for an aircraft comprising:

a housing having a surface,

a magnetic circuit formed by a stack of laminated sheets and composed of a yoke, the magnetic circuit being cut out of the laminated sheets in one portion, the magnetic circuit and the yoke being formed in one part, said yoke being attached on the surface of said housing by a thermal interface, said yoke having a surface, and

at least one low-frequency coil component, said coil component being attached to at least one portion of the surface of said yoke by attachment means.

2 . The electrotechnical device of claim 1 , wherein the thermal interface is a thermal paste, and wherein the yoke is glued to the surface of the housing.

3 . The electrotechnical device of claim 1 , wherein the thermal interface comprises a phase change material.

4 . The electrotechnical device according to claim 1 , wherein the surface of the housing and/or the surface of the yoke is flat.

5 . The electrotechnical device according claim 1 , wherein the surface of the housing and/or the surface of the yoke is concave or convex.

6 . The electrotechnical device according to claim 1 , further comprising a plurality of low-frequency coil components, said coil components being aligned on at least one portion of the surface of the yoke so as to form a line of coil components, and wherein each end of the line of coil components is attached to the surface of the yoke by the attachment means.

7 . The electrotechnical device according to claim 1 , further comprising a plurality of low-frequency coil components, wherein each coil component is attached to at least one portion of the surface of the yoke by the attachment means, the attachment means being arranged between each coil component.

8 . The electrotechnical device according to claim 1 , wherein the or each coil component is insulated from the yoke and its magnetic circuit by an electrically insulating material.

9 . The electrotechnical device according to claim 1 , wherein the housing and/or the yoke is equipped with cooling means.

10 . An aircraft comprising at least one electrotechnical device according to claim 1 .

11 . An electrotechnical device for an aircraft comprising:

a housing having a surface,

a magnetic circuit formed by a stack of laminated sheets and composed of a yoke, the magnetic circuit being cut out of the laminated sheets in one portion, said yoke having a surface and being attached on the surface of said housing by a thermal interface, said thermal interface being positioned between the yoke and the surface of said housing and being configured to perform a thermal exchange between said yoke and said housing,

at least one low-frequency coil component, said coil component being attached to at least one portion of the surface of said yoke by attachment means.
