Abstract: An electrical sheet includes an electrical sheet main body produced by additive manufacturing (a 3D screen printing method) from at least a first and a second material. The first and second materials have magnetic properties which differ from one another, and first and second domains are formed in the electrical sheet main body from the first and second materials respectively. An electric machine is also provided. An electric machine and a method for producing an electrical sheet for use in a stator or rotor of an electric machine are also provided.

Abstract: The present disclosure relates to rotor laminations having a first region and a second region, wherein the first region is larger than the second region and a first alloy is present in the first region and a second alloy is present in the second region. In accordance with the disclosure, the second alloy is soft-magnetic and has a higher magnetic permeability than the first alloy. The present disclosure further relates to an electric machine and an electrically powered vehicle. In addition, a method for producing the aforementioned rotor laminations is disclosed. For this purpose, a corresponding green part is printed in a stencil printing process and then sintered to form the rotor lamination.

Abstract: Methods and systems are provided for an electrical machine including a shaft configured to rotate about an axis of rotation, a rotor coupled to the shaft and a stator, wherein the rotor includes a first axial end face, a second axial end face, a lateral surface, and at least two cooling channels, wherein the cooling channels each extend into the rotor from an injection opening in the first axial end face, and at least one injection nozzle configured to spray a fluid into the injection opening of the cooling channels when the rotor is rotating.

Abstract: An electric machine includes a conductor structure having at least one metallic conductor element made from at least one of aluminum, copper, and silver having a monocrystalline or columnar crystal structure. The conductor structure may be formed from a plurality of individual flat conductor elements integrally bonded together by welding or soldering to form a winding. The metallic conductor element may be cut from an aluminum, copper, or silver bar having a monocrystalline or columnar crystal structure. A wafer having a plurality of conductor elements may be cut from a bar with the conductor elements separated from the wafer.

Abstract: A balance assembly for an engine is provided. The balance assembly includes a first electric motor coupled to the engine and configured to rotate a first eccentric mass relative to the engine, the first eccentric mass being coupled to a first shaft of the first electric motor, and a second electric motor coupled to the engine and configured to rotate a second eccentric mass relative to the engine, the second eccentric mass being coupled to a second shaft of the second electric motor. The first and second electric motors are configured to rotate the first and second eccentric masses in order to balance a vibration characteristic of the engine.
