Problems solved by technology

It is conceivable that such stamping is not suitable especially for smaller rotor diameters and higher rotational speeds, since the rotor is deformed due to the centrifugal load
An additional bandage for absorbing the centrifugal force reduces the air gap width, especially in the case of smaller electromechanical machines, and thus also makes the machine less efficient

Embodiment Construction

[0026] figure 1 A schematic longitudinal section through an electromechanical machine 1 with a reluctance rotor 5 is shown. The stator 2 of the electromechanical machine 1 has a winding system 3 which engages in slots 4 (not shown in detail) of the stator core. The torque is transmitted to the shaft 6 by electromagnetic interaction with the rotor configured as a reluctance rotor 5 . Alternatively, if the electromechanical machine 1 is configured as a generator, the torque of the shaft 6 is converted generator-like into electrical energy via the reluctance rotor 5 .

[0027] The shaft 6 is held in a bearing 7 , wherein the bearing 7 is positioned in a bearing end shield 8 .

[0028] figure 2 The construction of the reluctance rotor 5 is shown in a perspective view, wherein a carrier 11 , in this case a plurality of carriers 11 , is arranged axially one behind the other on the shaft 6 . Disk-shaped edge elements 9 are arranged between the individual carriers 11 of each roto...

Abstract

The invention relates to a reluctance rotor (5) with a shaft hole into which a shaft (6) is inserted rotatably, at least one carrier (11) is disposed around the shaft (6) and has radial sides (14) as viewed in a circumferential direction. Subsegments (10) are arranged on the radial sides of the carrier and made of each anisotropic soft magnetic piece material to establish a rotor segment (13) which, as viewed in an axial direction, is disposed between two disk shaped edge elements (9) and forms a central segment.

Description

technical field [0001] The invention relates to a reluctance rotor, an electromechanical machine having such a rotor, the use of such a machine and a method for producing a reluctance rotor. Background technique [0002] A reluctance rotor utilizes the different dielectric constants of the stack of laminations to generate torque. In this case, the different dielectric constants, Ld axes and Lq axes are achieved by stamping on the laminated core. It is conceivable that such punching is not suitable especially for smaller rotor diameters and higher rotational speeds, since the rotor is deformed due to the centrifugal load. An additional bandage for absorbing the centrifugal force would reduce the air gap width, especially in the case of smaller electromechanical machines, and would thus also make the machine less efficient. Contents of the invention [0003] Proceeding from this, the invention is based on the object of providing a reluctance rotor for electromechanical mac...
