Various embodiments include a method for sintering a multicomponent sinter product comprising: forming a first component consisting of a first material printed with one or more recesses for a second component; forming the second component consisting of a second material; inserting at least a portion of the second component into the one or more recesses of the first component; and shrinking the first component and the second component onto one another by sintering.

Various embodiments of the teachings herein include a magnetic sheet stack for an electric machine comprising: a plurality of magnetic sheets electrically insulated from one another by being spaced apart from one another predominantly with a non-vanishing clearance; a respective set of ceramic spacers distributed between each of the plurality of magnetic sheets from an adjacent sheet in the stack; and a respective gas layer filling a gap between a predominant part of a planar extent of each of the plurality of magnetic sheets allowing a cooling fluid to be circulated between the adjacent sheets.

A mechanical device for converting direct current into three-phase alternating current includes a contact unit having at least two receiving regions for receiving electrical energy as direct current and at least three output regions for outputting electrical energy as alternating current. A first receiving region contacts a positive pole of a direct current feed. A second receiving region contacts a negative pole of the direct current feed. A first output region provides a first alternating current, a second output region provides a second alternating current, and a third output region provides a third alternating current. A contacting unit receives the direct current and/or outputs the alternating current, and an assembly provides contact of the output regions with three phases of a dynamoelectric rotating machine. An isolator between two of the output regions and the contact prevents the contact from making contact with the two output regions at a same time.

In a method for producing a material sheet, in particular a metallic material sheet, a green body containing solid-state particles is sintered at a sintering temperature by heating the green body during sintering at least partly using microwave energy in accordance with a defined temperature profile having a heating phase and an essentially isothermal hold phase. A temperature of the green body is ascertained contactlessly with a sensor, and a supply of heat energy is controlled as a function of the temperature of the green body. During the heating phase an average microwave power is supplied and during the hold phase another average microwave power is supplied which is less than the one average microwave power.

A complex ring element includes first and second rings arranged such that their axes lie on a shared axis and disposed adjacent to one another when viewed in the direction of the shared axis, with one of the first and second rings representing a shaft of a rotor or being connected to a shaft of the rotor. A connecting element made of metal interconnects the first and second rings of metal such that outer peripheral surfaces of the first and second rings are partially overlapped when viewed in the direction of the shared axis. The connecting element is configured to extend circumferentially as viewed in the peripheral direction about the shared axis and is produced by an additive application method.

Various teachings herein may be used to make a bearing bush for a rotating shaft, wherein a wall of the bearing bush has a wall thickness which amounts to less than 10% of the diameter of the bearing bush. In the axial direction, the bearing bush is made from a plurality of layers connected with a material bond. Each layer has a layer thickness between 10 μm and 200 μm and the wall has closed cavities which are filled with a powder.

In a method for producing a material layer with a recess, a first suspension containing a binder is applied through a first opening in a first template and a second suspension containing a binder and solid particles is applied through a second opening in a second template. The first opening in the first template is completely contained within the second opening in the second template such that the second suspension completely surrounds the first suspension to produce a green body. The green body containing the first and second suspensions is sintered such that the first suspension is evaporated to provide the recess and permanent cohesion of the solid particles in the second suspension is achieved.

In a method for producing a cooling structure over a surface of a housing of a dynamo-electric rotational machine, at least one material is applied in layers by an additive manufacturing method to the surface of the housing, omitting at least one predefined region. As a result of the application of material, at least two elevations are formed, with a cooling channel being formed between the two elevations.

In a method for producing a material layer by an additive process, a first suspension with binding agent and solid particles is applied through a first template onto a base area to obtain a first green body, thereby reproducing by the first template a first material region of a first material to form a magnetic flux-conductive region with a first magnetic permeability μr>50. A second suspension with binding agent and solid particles is applied through a second template onto a base area to obtain a second green body, thereby reproducing by the second template a second material region of a second material to form a flux-blocking region with a second magnetic permeability μr<5. The first and second green bodies are joined and a permanent, material-bonded cohesion between the first and second green bodies and the solid particles is created by heating and/or by compaction.

A method for manufacturing an electric machine having a stack of magnetic laminations including a stack of green blanks. A first green blank of the stack is printed. A separating layer is applied to the first green blank. At least a second green blank of a magnetic lamination is printed onto the first green blank with the separating layer.

In a method for producing a material layer for a rotor of a dynamoelectric rotary machine, a first suspension with binding agent and solid particles is applied through a first screen onto a base to form a first green body, thereby reproducing a first region of a first material with a first degree of strength. A second suspension with binding agent and solid particles is applied through a second screen onto a base to form an annular second green body concentrically to a layer center, thereby reproducing a second region of a second material with a second degree of strength being higher than the first degree of strength. The first and second green bodies are joined such as to form a material recess substantially at a layer center. A permanent material bond of the first and second green bodies and the solid particles is created by heating and/or by compression.

In a method for producing a material layer with a layer thickness between 0.5 and 500 &#x3bc;m, a suspension with a binding agent and solid particles is applied through a template onto a base area for obtaining a green body. The binding agent is driven out of the green body and a permanent cohesion of the solid particles is created by heating and/or by compaction.
