Abstract: A rotor shaft for an electric machine includes a rotor shaft main body and a rotor shaft core which is arranged therein and which is connected to the rotor shaft main body. The rotor shaft comprises a substantially axially running cooling cavity configured to conduct a cooling fluid, and the rotor shaft core is composed of a different material than the rotor shaft main body.

Abstract: A stator for an electrical machine, in particular for an electromotive drive machine for an electric or hybrid vehicle, includes a stator core stack with a stator yoke and a number of radial stator teeth, as well as a corresponding number of stator slots, arranged between the stator teeth, for receiving a stator winding. A cooling apparatus has a number of cooling channels, each of which runs axially in one of the stator slots.

Abstract: A method for producing a cage rotor for an asynchronous machine has the following steps: providing a laminated rotor core made of a plurality of stacked rotor laminations which each have a plurality of rotor lamination grooves distributed in the circumferential direction; placing rod-shaped wire bundles, which are each made up of a plurality of wires, into the rotor lamination grooves; rotating the individual rotor laminations relative to each other, thereby deforming the wire bundles; placing short-circuit rings on both end faces of the laminated rotor core, and connecting the wire bundles to the short-circuit rings.

Abstract: A cage rotor for an asynchronous machine is provided. The cage rotor includes a laminated rotor core made of a plurality of stacked rotor laminations, which each have a plurality of rotor lamination grooves distributed in the circumferential direction. The cage rotor also includes short-circuit rings which are provided on both sides of the laminated rotor core and which each have a plurality of short circuit ring grooves distributed in the circumferential direction, and short-circuit bars which are inserted in the rotor lamination grooves, which extend through the short circuit ring grooves and the ends of which project beyond the short circuit rings. The short circuit ring grooves are open radially outwards and the short circuit bars with the short circuit rings are connected to each other at the side of the short circuit grooves which is at least partially open radially outwards. A method for producing such a cage rotor is also provided.

Abstract: A connection ring arrangement, includes a plurality of conducting rings, and a support element which holds the plurality of conducting rings. The support element has a projection arrangement having two projections which are designed receive the conducting ring and which extend from said conducting ring. The projection arrangement has an open end and a closed end, which closed end receives the conducting ring. The distance between the projections is at least partially smaller than the diameter of the conducting ring and at least one projection is at least partially elastically formed in a direction transverse to the longitudinal direction of the projection. The projections are designed such that the conducting ring is inserted between the projections.

Abstract: A new class of non-glycosidic and non-peptidic inhibitors of selectins with low molecular weight according to the general formula 1 is described, as well as methods for their production. These compounds represent a new class of non-toxic, in vivo anti-inflammatory effective inhibitors of selectins, and do not exhibit the disadvantages of the glycosidic inhibitor complexes, and are furthermore more potent in vitro, compared to the known drug bimosiamose. Furthermore, medicaments containing the compounds and their uses in the treatment of diseases are described.
