Abstract: A method for cooling an electrical machine includes the following steps: guiding a coolant in an axial coolant supply line which is arranged in the rotor shaft, and conducting the coolant into an interior chamber of the electrical machine via a radial coolant supply line which is connected in a coolant-conducting manner to the axial coolant supply line. The electrical machine has an axial coolant supply line and at least one radial coolant supply line connected in a coolant-conducting manner to the axial coolant supply line, both of which are arranged in the rotor shaft. An interior chamber of the electrical machine is connected in a coolant-guiding manner to the radial coolant supply line.

Abstract: A rotor for a separately excited inner rotor synchronous machine of an electrically drivable motor vehicle, having a plurality of rotor windings for forming a rotor magnetic field and a rotor core for holding the rotor windings, wherein the rotor core has an annular rotor yoke with a number of rotor poles corresponding to a number of rotor windings. The poles are arranged along a rotor circumference on the rotor yoke and the rotor windings are arranged on the poles, wherein the rotor poles are formed of multiple parts and each has a rotor tooth and at least one pole shoe element separate therefrom. The rotor teeth are formed as a single piece with the rotor yoke, and the pole shoe elements are mechanically connectable to the rotor teeth after arranging the rotor windings on the rotor teeth. Also provided are the synchronous machine, a motor vehicle and a method.

Abstract: An apparatus for enclosing objects, for example, candies, with a sheet of packaging material has a tube forming and guiding apparatus. To tightly fit the tube to the objects, an elastic collar is arranged at the end of the tube forming and guiding apparatus in the shape of a funnel and under tension, so that the collar presses the tube against the objects and forces superfluous packaging material into an overlap of the packaging material edges.

Abstract: An apparatus for sealing packaging containers formed at least in part of a bondable material. The apparatus includes a first bonding unit and a second bonding unit which are fixedly disposed with mutual spacing on an endless conveyor. A device is provided for removing a covered container from the first bonding unit, after the container is provided with a first bonded seam therein by application of heat and pressure, and transferring it to the second bonding unit. This removing and transferring device is disposed on the common path of rotation of the two bonding units. The second bonding unit effects the application of a second bonded seam to the covered container.
