An electromagnetic element for an electric machine, having multiple slots arranged in the circumferential direction of the electromagnetic element, said slots extending in the axial direction of the electromagnetic element and having an open side in the radial direction. A coil device is arranged in the slots, said coil device having winding heads on (at least) one axial end face of the electromagnetic element, and a cooling channel is formed in the slots in order to dispense heat from the coil device using a fluid. A wall element is also provided which has a first region that is arranged in the region of the winding head in the circumferential direction. and a second region of the wall element, said second region adjoining the first region and having teeth which extend in the axial direction and are arranged on the open side of the slots in the intermediate spaces between the slots in the circumferential direction.

A method for soldering a stator of an electric machine to a cooler is described. Firstly, the stator and/or the cooler is coated, at least partially, with a layer of solder. Then, the stator is brought together with the cooler such that the layer of solder is between the stator and the cooler. Finally, the cooler is heated to the melt temperature of the layer of solder in order to produce a solder connection between the stator and the cooler. The cooler can also act as support. Furthermore, a stator for an electric machine, comprising a stator support and a solder connection between the stator and the stator support is described.

An electronic power circuit includes several power modules ( ) and is especially for controlling an electrical machine. Each power module ( ) includes a plate-shaped integrated electronic circuit arrangement ( ) having several electrical terminals. A perpendicular bent-over electrically conducting side leg ( ) is arranged on each of two opposite-lying sides of the plate-shaped circuit arrangement ( ). The side leg ( ) forms an electrical contact and, in this way, the power module ( ) has a U-shaped cross section. Each side leg ( ) is provided with connecting elements via which two or several power modules ( ) can be electrically and mechanically fixedly connected to each other while forming a mutual spacing between the plate-shaped circuit arrangement ( ) via the side legs ( ) for forming the electronic power circuit.
