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.

Abstract: An electric disk armature machine is disclosed which comprises a drive shaft for the transmission of power from and to the rotor of an electric disk armature machine and which has at least one driver disk vertical to the shaft axis for a positive and/or frictional connection with the rotor. The rotor is a self-supporting construction of a plurality of plate-like coil elements which are distributed along the circumference and which are interconnected radially outside and radially inside so as to conduct. The commutator is formed by an annular portion of one end side of the rotor and an insulating layer is arranged between the rotor and the drive shaft. The electric disk armature machine also comprises a rotor which contains a plurality of current conducting coil elements which are turned relative to one another in their radial angular position and which are insulated relative to one another and arranged in one or more different planes vertical to the rotor axis.

Abstract: A rotating collector for electrical machines including a carrier bushing onto which a rim of collector segments is attached. The carrier bushing has first, swallowtail-type attachment devices in the form of circumferential crosspieces having slits formed therein and ring grooves, into which second swallowtail-type attachment devices formed on each collector segment are inserted at an angle to the carrier bushing axis. Each inserted collector segment is then oriented in the axial direction to create an intermeshing arrangement to complete the rim.

Abstract: A collector includes a carrier bushing, onto which a rim of collector segments is attached by means of swallowtail-type attachment devices. An intermediate space remaining between the carrier bushing and the collector segments is filled with a casting material. An interlocking swallowtail arrangement is used, which fixes the collector segments radially to the carrier bushing in such a way that they cannot come loose. The carrier bushing has a T-profile groove, into which the collector segments can be inserted and pushed onto the carrier bushing in the circumferential direction. After the collector segments have been installed, the T-profile groove is closed with a wedge, which also has a swallowtail structure to hold the single remaining collector segment.
