Abstract: The present invention relates to a method for manufacturing an electric motor having a stator with stator slots and electrical conductors arranged therein. In order to achieve simple production, the following is planned, that at least two electrical conductors are sheathed in an extrusion process with an electrical insulator, which holds the at least two electrical conductors at a distance from one another and has at least one positioning contour, that the at least two electrical conductors together with the electrical insulator are inserted into an associated stator slot and fixed therein via the at least one positioning contour.

Abstract: A cooling system for a vehicle may include a cooling circuit through which a coolant is flowable. The cooling circuit may include a first heat source, a first radiator, a second heat source, a second radiator, and a hydraulic switch. The first heat source may be coolable at a lower temperature level. The second heat source may be coolable at a higher temperature level. The first heat source, the first radiator, the second heat source, and the second radiator may be connected in series with one another in the cooling circuit. The hydraulic switch may divide the cooling circuit into (i) a first partial circuit with the first heat source and the first radiator and (ii) a second partial circuit with the second heat source and the second radiator.

Abstract: A filtering system for filtering air is provided, which contains a filter for filtering particles out of the air and an ionizer that contains at least one electrode assembly upstream of the filter. An improved and longer filtering effect is obtained in that at least one of the electrode assemblies generates a negative corona discharge in a first operating mode, and at least one of the electrode assemblies generates a positive corona discharge in a second operating mode. An air conditioner and a vehicle that has such a filtering system is provided.

Abstract: An air filtering device for an air conditioner, in particular for filtering out particles, preferably pollutants, from air is provided. The air filtering device comprises a flow path through which air flows along a flow direction, an ionizer for generating ions in the flow path, and grid structure made of an electrically conductive material, that is upstream of the ionizer in the flow path in the flow direction, which forms a first electrode. A filter is downstream of the ionizer in the flow path in the flow direction which has a layer that forms a second electrode. The air filtering device also comprises a high voltage power source that has an electric pole and an electric counter-pole for generating a high voltage between the pole and the counter pole. The pole is electrically connected to the ionizer, or its discharge electrode, and the counter-pole is electrically connected to the first and second electrodes.

Abstract: An inductively electrically excited synchronous machine is disclosed. The synchronous machine includes a stator group with a housing and a stator arranged in the housing and a rotor group with a shaft and a rotor that is non-rotatably connected to the shaft. The rotor group is rotatably arranged about an axis of rotation in the stator of the stator group. A bearing shield and a bearing fixed in the bearing shield are provided. The bearing shield axially closes the housing of the stator group and the bearing rotatably receives the shaft of the rotor group. An energy transmitter with a hollow-cylindrical magnetic core is provided. The magnetic core is arranged radially between the bearing shield and the bearing and partially forms the bearing shield.

Abstract: A heat exchanger for use in an outdoor environment with a heat pump system is provided. The heat exchanger includes a first set of tubes arranged in a parallel flow manner between a first manifold and a second manifold, wherein central straight portions of adjacent tubes are disposed with a space therebetween along each tube of the first set of tube between the first and second manifolds. A second set of tubes are arranged in a parallel flow manner between a third manifold and a fourth manifold, wherein central straight portions of adjacent tubes within the second set of tubes are at least partially disposed within the space between adjacent tubes of the first set of tubes. A fluid that flows through the first set of tubes additionally flows through the second set of tubes before the fluid returns to again flow through the first set of tubes.

Abstract: A position encoder for a camshaft is disclosed. The position encoder includes an annular base body arranged in a base plane and having a central longitudinal axis extending vertically in relation to the base plane along an axial direction. At least one signal tab projecting radially outward integrally formed on an outer circumference of the base body. One recess respectively is provided at a transition to the bent signal section on two sides delimiting the signal tab in the circumferential direction. An axial end face of the bent signal section of the signal tab tapers at least in a tapered section in a longitudinal section along the axial direction, from radially outwards to radially inwards toward the base body.
