Abstract: Various embodiments of the teachings herein include a canned electrical rotating machine or liquid pump. The machine or pump may include a can made of a first material. The first material comprises, at least in a proportion of more than 50% by weight, a composite material with high-modulus or ultrahigh-modulus (HM/UHM) carbon fiber reinforcement.

Abstract: Various embodiments of the teachings herein include an end plate comprising: a device for receiving a bearing internally with an inner fastening circle; and fasteners for fastening the end plate to the housing of the electric machine externally with an outer fastening circle. The end plate has a geometry suitable for counteracting the deformation of the first natural frequency overcoming a flat and/or planar shape, or side, respectively, of the end plate by bending the end plate, with the same or a reduced mass and/or wall thickness of the end plate.

Abstract: Various embodiments may include a metallic component comprising: a base metal form with at least one surface; and an organic protective layer applied to at least part of the at least one surface to reduce friction. The organic protective layer is applied by treatment with a carbon-containing precursor by means of an atmospheric pressure plasma.

Abstract: A surface coating for high-grade white and/or gray goods, i.e. items for domestic, sanitary and/or automotive use, in particular housing elements of corresponding devices and machines, as well as decoration, for example those housing elements which specifically have metallic applications and/or elements is disclosed. The surface coating is applied on a metallic or metalized surface structure and has hydrophobic property and/or oleophobic property. The surface coating is defined by a thickness which is less than a structure depth of the surface structure. The height of the surface roughness of the surface structure can thus extend significantly beyond the thickness of the surface coating, so that the surface structure promotes blurring of undesired residues in a kind of intrinsic capillary/channeling effect. Because of the blurring the contour of a soiling is obscured until finally it becomes wholly indistinguishable.
