Abstract
An electric axial flow machine includes an ironless disk-shaped rotor arranged on a machine shaft and having permanent magnets embedded in a fiber- or fabric-reinforced plastic, and, on both sides, next to the rotor, a stator, wherein the permanent magnets are each joined to the surrounding fiber- or fabric-reinforced plastic so that the permanent magnets and the machine shaft form a dimensionally stable unit.

An electric axial flow machine including an ironless disk-shaped rotor arranged on a machine shaft and having permanent magnets embedded in a fiber- or fabric-reinforced plastic, and, on both sides, next to the rotor, a stator, wherein the permanent magnets are each embedded in and joined at least peripherally in an interference fit with the fiber- or fabric-reinforced plastic so that the permanent magnets and the machine shaft form a dimensionally stable unit.
A method for producing an ironless disk-shaped rotor for arrangement on a machine shaft of an electric axial flow machine and having permanent magnets embedded in a fiber- or fabric-reinforced plastic, including placing the machine shaft and the permanent magnets in a mold, heating the mold, and injecting a pre-heated fiber- or fabric-reinforced plastic under pressure into the heated mold to establish an interference fit between the permanent magnets and the fiber- or fabric-reinforced plastic.
