Abstract: A stator device for an electric machine includes a stator, having a stator core with a longitudinal axis, a first end face and a second end face which is situated axially opposite the first end face with respect to the longitudinal axis, and having a stator winding which forms a winding head on the first end face and has a plurality of connection portions extending beyond the winding head. The isolating body has a plurality of holding elements, which protrude from the base portion on the second side and are designed to hold the isolating body radially on the winding head.

Abstract: A rotor for an electric machine includes a laminated core formed from stacked electrical laminations and having magnet pockets arranged therein, a plurality of magnets, of which at least one is inserted into each of the magnet pockets, and a plurality of clearances which are in each case delimited by the magnets inserted into one of the magnet pockets and by the laminated core. A first connection channel connects a first one of the clearances which is associated with a first one of the magnet pockets to a second one of the clearances which is associated with a second one of the magnet pockets. An electric machine may include such a rotor, and a vehicle may include such an electric machine.

Abstract: 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.

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.

Abstract: The invention relates to a terminal board for fastening electrical lines including at least one threaded hole so as to fasten a connecting element of an electrical line by way of a screw that can be screwed or is screwed into the threaded hole, wherein the terminal board includes a cylindrical insert having the threaded hole, and the connecting element and the insert are joined to one other by way of plastic deformation. The invention furthermore relates to a method for fastening electrical lines to a terminal board.

Abstract: A cooling jacket includes a jacket having an axial end provided with an opening, and a sealing structure which is arranged in the opening. A member selected from the group consisting of the jacket and the sealing structure has a radial deformation to connect the jacket to the sealing structure. The radial deformation is configured to extend into the opening.
