摘要： A rotor for a dynamoelectric rotary machine includes a rotor stack, a plurality of permanent magnets, and a binding designed to fix the permanent magnets to the rotor stack, said binding including a binding thread. The permanent magnets each have at a surface of the permanent magnet a shape deviation designed to receive the binding thread and to comprise a conical thickening and an indentation, with a height difference between a highest point of the thickening and a lowest point of the indentation being at least 2% of a thickness of the permanent magnet and at most 20% of the thickness of the permanent magnet.

摘要： An electric machine includes a stator having 48 grooves and 48 tooth coils, and a rotor interacting with the stator. The rotor has eight magnetic poles along an external circumference of the rotor in an annular arrangement, with adjacent magnetic poles defining angular distances defined successively at 41.25°, 39.75°, 41.25°, 57.75°, 41.25°, 39.75°, 41.25° and 57.75°. The angular distances have a tolerance range of 0.4°. The electric machine has a pole arc between 0.6 and 0.7.

摘要： 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.

摘要： 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.

摘要： The aim is to propose an individual-segment rotor that is simple to construct and suitable for series production. Therefore, an individual-segment rotor having a plurality of laminated core segments (2) arranged in a star shape and a permanent magnet (1) between each pair of adjacent laminated core segments (2) is provided, whereby the laminated core segments and the permanent magnets are arranged in a hollow cylindrical assembly. The laminated core segments each have a plurality of individual sheets, which are rigidly connected to one another. The hollow cylindrical assembly has a groove on each of two outer edges, into which groove a ring (11) is inserted in order to fasten the assembly.

摘要： 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.

摘要： An active part for an electric machine can be configured as a stator or a rotor and includes at least two slots for arranging an electric coil winding of an electric coil. Arranged between the two slots is a crosspiece which is made of a material for conducting a magnetic flux through the electric coil which surrounds the crosspiece. The material has, at least in one area, magnetic anisotropy with an easy magnetization axis, which is oriented parallel or at least at an angle of less than 25° with respect to a coil axis of the coil, and a hard magnetization axis. The crosspiece is configured to form for each of the slots a slot wall which contains the material. The crosspiece includes a core which is made of an isotropic soft-magnetic material.

摘要： In a method for producing a material layer with a void, 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 void and permanent cohesion of the solid particles in the second suspension is achieved.
