A method for maintenance, repair and/or optimization of a battery. The battery has, as components, individual cells connected to one another in series and/or in parallel, having electrical terminal contacts which are connected to one another positively and/or firmly, directly or by cell connectors, forming an overlapping region, and/or a battery monitoring unit having a number of connection elements which are positively and/or firmly connected to the electrical terminal contacts and/or to the cell connectors, forming a further overlapping region. To exchange a component, the positive and/or firm connection of the component to be exchanged to at least one component not be exchanged is separated directly next to the overlapping region and a replacement component is connected positively and/or firmly to the overlapping regions of the at least one component not be exchanged by the electrical terminal contacts thereof or the connection elements thereof, forming a respectively new overlapping region.

A rotor for a rotating electric machine includes a plurality of pole teeth supporting an excitation winding, grooves respectively formed between the pole teeth, and wedges provided in the grooves, each wedge having a concave shape with a bulge oriented towards the inside of the rotor.

Rotor for a rotating electric machine

A blade wheel for a rotary electric machine may include a hollow cylindrical main body having an outer surface extending around an axis of rotation in a circumferential direction of the main body; a first end region and a second end region of the main body, each peripherally extending around the main body in the circumferential direction, the first and second end regions lying opposite each other in the direction of the axis of rotation; a recess extending along the outer surface and between the first end region and the second end region of the main body in the circumferential direction; and at least one web-shaped vortexing element extending within the recess and between the first and second end regions. The at least one vortexing element is designed to generate a movement of air away from the outer surface when the blade wheel rotates about the axis of rotation.
