Abstract: An injection mold, in particular for encapsulating rotors of electric machines, has a mold, wherein the mold has an arrangement of mold segments. The arrangement forms, along a longitudinal axis, a cavity for a component to be arranged. An exchange unit is provided, which is designed to remove at least one mold segment from and/or insert at least one mold segment into the arrangement, with the result that a size of the cavity can be changed.

Abstract: A rotor, in particular of an electrical machine, has a base body and at least one metallic end plate which is mounted on the base body. The base body and the at least one end plate have a continuous layer which is injection molded.

Abstract: A method produces a rotor having at least one laminated core for an electrical machine, in which method at least one partial region of the rotor is provided with a plastic by injection molding. The method provides at least one disk following the laminated core in the axial direction of the rotor, by which disk the partial region is at least to a large extent delimited in the axial direction of the rotor; and by the injection molding, injects the plastic into the partial region via at least one through-opening in the disk leading into the partial region.

Abstract: An electrical machine includes a rotor with a plurality of winding slots in which wire windings are arranged. A pair of covering slides is associated with each winding slot, wherein each covering slide has a closure wall, and the closure walls of the pairs of covering slides close the winding slots which are associated with them on that side of the winding slots which faces radially outward. Mutually facing longitudinal ends of the closure walls of the same pair of covering slides overlap in the assembled state in such a way that the closure walls of the same pair of covering slides overlap only in sections.

Abstract: A rotor of a current-activated electric machine has a plurality of windings which are arranged on the rotor, slots being formed between the windings. A textile has a plurality of fibers connected to one another in flat contact. The textile is arranged in at least one slot, and the textile is impregnated with a filling material which in the normal operational state of the rotor is in a solid state.
