Abstract: An arrangement of components for transferring electric current from a current-feeding component to a current-discharging component, including a first component, which feeds current to the arrangement or discharges current from the arrangement. The first component includes a first metallic material and, on at least one surface, has at least one spring lamella composed of the first metallic material and machined out of the first metallic material at the surface. The lamella is machined out of the first metallic material at the surface of the first component such that it is connected monolithically to the first component in a connecting region and, starting therefrom extends as far as a free end and, when deflected out of a rest position toward the surface of the first component, exerts a spring force directed away from the surface. A second component is in immediate contact with the lamella of the first component.

Abstract: A squirrel-cage rotor having at least one laminated rotor core and a method of manufacturing the same are provided. Short-circuit rings in the squirrel-cage rotor are provided with at least two metal composite discs. A metal composite disc includes at least a first metal disc and a second metal disc connected to the first metal disc, where the second metal disc is made of a different material from the first metal disc. Adjacent metal composite discs are arranged such that the first metal discs face one another. The short-circuit rings are attached at an end face to the rotor core. Conductive rotor bars are attached to the first metal disc in the region of slots arranged in the outer periphery of the short-circuit rings.

Abstract: A squirrel cage rotor having a shaft, a rotor plate stack with rotor bars arranged in the interior thereof, and cage rings, wherein at least one part of a cage ring includes a disk stack, which is constituted as a layered structure of disks with cut-outs, through which the ends of the rotor bars project out of the rotor plate stack. Adjoining disks in the disk stack are mutually spaced, and form a gap. The clearance between two adjoining disks, resulting from the gap, is constituted by moldings which are arranged on the disks wherein, in the gap, at least in the region of the moldings, a joint connection is provided.

Abstract: A squirrel cage rotor, is made up of a shaft, a rotor laminated core with rotor bars which are arranged in the interior, and short-circuiting rings with clearances through which the bar ends of the rotor bars extend out of the rotor laminated core. The rotor bars, on their surface, at least partially have an electrical insulation layer, wherein the electrical insulation layer is cohesively connected only to the surface of the rotor bars. The squirrel cage rotor is intended, in particular, for use in an asynchronous machine.

Abstract: A sliding element which has a main body and a layer system which is applied thereto. The layer system has at least a first layer of the thickness s1, which is applied to the main body, and hard material particles having a mean extent d, which are introduced into the first layer and are therefore at least fixed on the main body. The thickness s1 of the first layer is such that it amounts to at least 60% and at most 90% of the mean extent d of the hard material particles, and the hard material particles form a surface structuring of the sliding element.

Abstract: A method for producing a device for measuring current strengths. The method includes providing a resistor arrangement with two connection elements and a resistor element arranged between the connection elements, molding a contact element from the material of the connection element or from the material of the resistor element. The contact element has an end face remote from the resistor arrangement and a cavity open on the end face. The method further includes providing a circuit board with a through-bore on whose inner surface electrically conductive material is present, positioning the circuit board on the resistor arrangement such that the contact element projects into the through-bore, and expanding the contact element in the radial direction using an expansion element inserted into the cavity of the contact element to establish an electrically conductive connection between the contact element and the electrically conductive material on the inner surface of the through-bore.
