Abstract: A disclosed method for operating a treatment system and to a treatment system for electrophoretic dip coating, more particularly dip painting of a metal workpiece, more particularly of a vehicle body, in a dipping tank filled with a paint, wherein: a relative movement between the workpiece and a bus bar is carried out in the dipping tank; a voltage is applied to the workpiece; and, while the workpiece is in the effective range of at least one bus bar portion of the bus bar, electric current is fed to the workpiece from the at least one bus bar portion at least some of the time. Examples disclosed herein also relate to a treatment system and to a computer program product.

Abstract: Connection unit for a stator with a stator winding having a number N of phases, having first to Nth contact portions, which are each designed for electrically conductively contacting one of N connection portions of the stator, form a receiving chamber for receiving one of the connection portions and have a guide. A respective contact portion has a wall, which limits the receiving chamber on one side, and the guide of the contact portion has a wall, which adjoins the wall of the contact portion and is bevelled with respect to the wall of the contact portion in a manner facing away from the receiving chamber. A conductor arrangement, which either electrically conductively connects the first to Nth contact portions or comprises N conductor portions, which are electrically isolated from one another and are each electrically conductively connected to one of the contact portions.

Abstract: 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.

Abstract: Described is an electrical machine (1) which comprises two end shields (6, 7), a stator (5) which is arranged between the two end shields (6, 7) and has a stator laminated core (11, 11a) and stator windings (12) arranged therein, and a rotor (3) which is arranged in the stator (5) and has a rotor shaft (2) mounted rotatably in the two end shields (6, 7). The electrical machine (1) furthermore has cooling channels (13) arranged fully in the stator laminated core (11, 11a) and edged by the latter. Furthermore described are a gear motor (30) comprising such an electrical machine (1), as well as a vehicle (20) comprising such an electrical machine (1).

Abstract: Connection unit for a stator having a stator winding with N number of phases. The connection unit includes a number N of contact portions each having a first wall and a second wall, and each contact portion forming a receiving chamber delimited by the first wall and the second wall and designed to encase one of N connection portions of the stator. Each contact portion is configured to electrically contact the connection portion, wherein the first and second walls of the N contact portions are oriented parallel to one other. A conductor arrangement which either electrically conductively connects the contact portions or includes N conductor portions which are electrically isolated from one another and are each electrically conductively connected to one of the N contact portions.

Abstract: A method for producing an intermediate product for an electrical machine includes supplying a mould for a housing part. A stator laminated core is laid inside the mould and the housing part is produced by introducing a molten metal alloy into the mould. The molten metal alloy comes directly into contact with the stator laminated core. The method relates to an electrical machine with such an intermediate product, and a vehicle with such an electrical machine.

Abstract: A rotor for an electric machine includes a sheet metal package formed from stacked electrical sheets and having magnet pockets arranged therein, a plurality of magnets of which at least one is inserted into each of the magnet pockets, a plurality of clearances which are each delimited by the magnets inserted into one of the magnet pockets and by the sheet metal package, a filling opening which is arranged on an axial side of the sheet metal package and through which a first of the clearances is exposed, and a venting opening which is arranged on the axial side and through which a second of the clearances is exposed. The outer end of the filling opening and/or the outer end of the venting opening are widened. Also described are an electric machine having the rotor, a vehicle having the machine and a method for producing the rotor.
