Embodiment Construction

[0041] exist figure 1 The rotor laminations 2 of the rotor 12 according to the invention for a reluctance motor 18 , which are not shown in detail here, are shown in . Such a reluctance motor 18 in Figure 7Schematically shown in , the reluctance motor is an electric machine comprising a rotor 12 and a stator 20 . The reluctance motor 18 has a housing 22 in which the rotor 12 is rotatably mounted on a shaft 24 . The individual rotor laminations 2 are inserted successively onto the shaft 24 and form a single lamination pack here. In operation, the rotor 12 rotates about the axis D. As shown in FIG. Furthermore, the stator 20 is inside a housing 22 .

[0042] according to figure 1 The rotor lamination 2 has a multiplicity of magnetic laminations 4 made of a material with high magnetic permeability, for example iron. The laminations are separated from each other by non-magnetic regions, which in the exemplary embodiment shown are arc-shaped grooves 6 , which are formed in p...

Abstract

The invention relates to a rotor (12) having several rotor laminations (2), which are stacked one after the other along an axis of rotation (D), wherein each rotor lamination (2) has a plurality of magnetic fins (4), which are separated from each other by nonmagnetic hollows (6), the nonmagnetic hollows (6) are arcuate and the two ends (7) of the nonmagnetic hollows are open toward an outer circumference (U) of the rotor lamination (2), the hollows (6) of at least some of the rotor laminations (2) are filled with a solid material (16). For the purpose of a simple design and improved functionality of the rotor (12), the stacked rotor laminations (2) are connected to each other only in the direction of the axis of rotation (D) in the assembled state of the rotor (12).

Description

technical field [0001] The invention relates to a rotor for a reluctance motor, comprising a plurality of rotor laminations stacked one behind the other along the axis of rotation, wherein each rotor lamination has a plurality of magnetic laminations which pass through each other through non-magnetic recesses. The slots are divided, wherein the non-magnetic grooves are arc-shaped and open at both ends towards the outer circumference of the rotor laminations, wherein the grooves are filled with solid material. [0002] The invention also relates to a method for producing such a rotor for a reluctance motor. [0003] The invention also relates to an electric machine, in particular a reluctance electric machine. Background technique [0004] An electric machine is a device which converts electrical energy into mechanical energy, in particular kinetic energy (motor operation) and / or mechanical energy into electrical energy (generator operation). A rotating electrical machine i...
