Abstract: The invention relates to an electrical machine (10), comprising at least one first coil (12), which is surrounded by a first electrical insulation element (24) at least in a partial region, and at least one second coil (14), which is surrounded by a second electrical insulation element (26) at least in a partial region, wherein at least one electrically conductive layer (28) provided in addition to the coils (12, 14) and in addition to the electrical insulation elements (24, 26) is arranged between the coils (12, 14).

Abstract: A rotor includes at least two rotor poles, a rotor iron core which has at least one cavity per rotor pole, wherein webs are formed between the cavities and the exterior of the rotor iron core in the radial direction and an embedded permanent magnet assembly for generating a magnetic air gap flux density, the assembly having at least one permanent magnet per rotor pole in the respective cavity. In order to influence the curve of the magnetic air gap flux density, magnetic flux blocking sections and magnetic flux conducting sections are arranged in an alternating manner in the at least one web of each rotor pole along the circumferential direction, wherein the magnetic flux blocking sections are designed to conduct a magnetic flux within the adjacent magnetic flux conducting section and have different geometries in the circumferential direction starting from a rotor pole center to rotor pole edges.

Abstract: The invention relates to an aircraft turbine having counter-rotating propellers and a primary drive, the noise development of which is significantly reduced with respect to aircraft turbines which have a primary drive based on the internal combustion principle. The invention relates to an aircraft turbine having counter-rotating propellers and a primary drive, the primary drive of which is based on the electric drive principle.
