摘要： A rotor for an electric machine includes a laminated core formed from stacked electric sheets and having a plurality of magnet pockets, each axially penetrating the laminated core, a plurality of magnets, of which at least one is inserted into each of the magnet pockets. A plurality of free spaces are each delimited by the magnets inserted into one of the magnet pockets and by the laminated core. A first end sheet is arranged on an axial side of the laminated core and a second end sheet arranged on the opposite axial side of the laminated core and has an axially curved portion by which a connecting channel is formed, which connects a first of the free spaces to a second of the free spaces.

摘要： A device in a motor vehicle includes two electric and/or electronic assemblies and a cable connection. The electric and/or electronic assemblies are electrically connected via the allocated terminals to at least two earth lines and at least two current-carrying lines of the cable connection. The cable connection has, for each current carrying line, at least one earth line which extends along the current-carrying line and in the same longitudinal direction as the current-carrying line. Also specified are an electric drive in a motor vehicle having such a device, and a motor vehicle having such a drive.

摘要： Connection device for a stator having a stator winding, including N phases, first and second connection units which each comprise N contact portions and a conductor arrangement. The contact portions of the first connection unit are each designed for electrically conductive contacting of one of N connection portions of the stator winding, and the conductor arrangement of the first connection unit electrically conductively connects the contact portions of the first connection unit. The contact portions of the second connection unit are each designed for electrically conductive contacting of one of N further connection portions of the stator winding and the conductor arrangement of the second connection unit comprises N conductor portions, which are electrically insulated from each other and are each electrically conductively connected to one of the N contact portions of the second connection unit. A fastening mechanism permits the connection units to be detached and fastened.

摘要： An oil cooling system for an electric machine that includes a housing and a stator accommodated in the housing, the stator having a first end part and a second end part in an axial direction of the electric machine. The oil cooling system includes an oil inlet, for receiving external cooling oil; a first annular oil application pipe, located at the first end part and in fluid communication with the oil inlet; and a second annular oil application pipe, located at the second end part and in fluid communication with the oil inlet. An axial oil application part is located between the first end part and the second end part and formed by a housing inner wall and a stator outer wall. The axial oil application part receives cooling oil from at least one of the first annular oil application pipe and the second annular oil application pipe.

摘要： Stator, which has N≥3 phases, P≥2 pole pairs and a hole count q=2 and also includes a stator core with a plurality of slots and a plurality of shaped conductors. The shaped conductors form for each phase a first and a second path and are arranged in 2·P winding zones which are each subdivided into a first and a second sub-winding zone. The shaped conductors of a respective path are interconnected to form a series connection with a first end-shaped conductor and a second end-shaped conductor by connectors, which connect shaped conductors in adjacent winding zones of the same phase in an alternating manner at two axial face sides. The shaped conductors of a respective path form a first to third section of shaped conductors successively in the series connection. The first and third sections include the first and second end-shaped conductor respectively.

摘要： A rotor for a rotary electric machine, capable of rotating around an axis of rotation, the rotor has first and second axial ends and includes a rotor body having a plurality of teeth circumferentially distributed around the axis and projecting radially, each tooth being in contact with two end plates. Also included is a rotor winding having a plurality of coils, each coil being wound on one of said teeth of the rotor body, each coil having two coil ends, two covers, a first cover located on the first axial end of the rotor and a second cover located on the second axial end of the rotor. The rotor has at least one non-conductive radial barrier that maintains a predetermined distance between the first coil end and the first cover on the one hand and between the second coil end and the second cover on the other hand.
