Embodiment Construction

[0026] The embodiments described in more detail below are preferred examples of the invention.

[0027] figure 1 A magnetoresistive coupler is shown as an example in a three-dimensional view. The magneto-resistive coupler is used to couple the first shaft 1 with the second shaft 2 . The reluctance coupling has a stator 3 which has an approximately tubular or hollow cylindrical shape. A first rotor 4 is rotatably supported inside the stator 3 . The rotor 4 is non-rotatably connected to the first shaft 1 . A second rotor 5 is mounted rotatably within the first rotor 4 . A second shaft 2 is fastened to this second rotor in a rotationally fixed manner.

[0028] The two shafts 1 and 2 are arranged coaxially with respect to the axis of rotation 6 . The first shaft 1 is remote from one end side of the magneto-resistive coupling, and the second shaft 2 is remote from the other opposite end side. The axis of rotation 6 then constitutes the center of rotation of the first rotor 4...

Abstract

The invention relates to a reluctance coupler with two rotors. A magnetic coupling of simple construction is provided here. A reluctance coupling for coupling a first shaft (1) to a second shaft (2) is proposed for this purpose, the reluctance coupling having a hollow cylindrical stator (3) with at least one Magnets (10), the one or more magnets are distributed around the periphery of the stator. Furthermore, the reluctance coupling has a first rotor (4), which is rotatably supported inside the stator (3), is connected to the first shaft (1) in a non-rotatable manner, and has a plurality of Ferromagnetic first sections separated from one another distributed over its circumference; the reluctance coupling also has a second rotor (5), which is rotatably mounted inside the first rotor (4) , which is non-rotatably connected to the second shaft (2) and has a plurality of ferromagnetic second sections distributed over its circumference.

Description

technical field [0001] The invention relates to a magneto-resistive coupler for coupling a first shaft with a second shaft. Background technique [0002] There are many solutions for magnetic couplers. Almost all of them are based on magnetic fields generated by permanent magnets. The simplest implementation of a magnetic coupling consists of two opposing rotating magnets. This results in a contactless, but inseparable coupler. A coupler realized with permanent magnets can also be realized switchable if one side of the coupler is realized with a rotating field winding. However, the costs are significantly higher. In particular, power is transmitted to the rotary shaft inductively or by means of sliding contacts. [0003] For many applications, however, a magnetic coupling between two rotating shafts is advantageous, which can transmit torque in a controlled manner by means of passing current. Forces can be transmitted without contact as required. In particular, discon...
