A cage rotor of an asynchronous machine includes a magnetically conductive body having substantially axially running slots with conductors connected to end faces of the magnetically conductive body in an electrically conductive manner by short circuit rings. The short circuit rings have an outer side, an inner side, a front side, and a rear side. A supporting element made of a high-strength material is located at least radially within the short circuit rings, i.e. on the inner face, with the supporting element being connected to the short-circuit ring, at least in one section, with a material fit.

Cage rotor with support element

Various embodiments include stator for an electrical machine comprising: a stator winding; and a yoke with a plurality of slots. There are a plurality of conductor segments connected to one another, wherein each conductor segment has one respective axially internal inner section and two respective axially external outer sections. The respective inner section of each conductor segment is embedded into a respective slot. Ducts for coolant flow in the axial direction are formed at least in a portion of each of the slots. The stator defines, at least in a first axial end region, a first coolant chamber fluidically encapsulated from a surrounding area. The first coolant chamber surrounds at least a portion of the respective outer sections of each of the conductor segments situated in the first axial end region. The first coolant chamber is fluidically connected to the ducts to conduct coolant into and/or out of the ducts.

Stator having winding cooling for an electrical machine

The method includes binding living cells to magnetic particles, adding them to a sensor array, uniformly distributing over the sensor array, magnetically fixing the magnetic particles having the bound cells over the sensor array, and adding substances to maintain and/or improve the cell vitality to the sensory array, and/or adding substances to worsen the cell vitality to the sensor array. The assembly includes a sensor array composed of sensors, which are designed to be in direct fluidic contact with a fluid, and a device for generating a magnetic field over the sensor array. A layer that comprises magnetic particles and living cells is formed on the sensor array.

Method and assembly for determining cell vitalities

A drive device for a motor vehicle includes at least one electric machine having at least one rotor element which includes a single-piece, essentially sleeve-shaped rotor carrier to delimit an installation area in a radial direction. At least one transmission device is disposed, at least partly, in the installation area and configured to be driven by the electric machine via the rotor element.

Drive device for a motor vehicle

A piston engine has a housing and a piston. The piston is magnetically and movably disposed in the housing. A device for magnetically supporting the piston is fixedly mounted relative to the housing. A linear machine in conjunction with the magnetic bearing of the piston can prevent friction and thus result in a machine for converting mechanical into electric energy without having to lubricate and with reduced mechanical effort.

The embodiments relate to a driven vehicle axle, which is coupled or can be coupled to an internal combustion engine and/or at least one electric machine that optionally can be operated as an engine or generator and which includes a brake device having an eddy current brake ().
