Definitions
- the present invention relates to a rotor for an electrical machine, wel cher has at least two poles and an even number of N> 6 staggered rotor modules, the rotor modules for a respective pole having a magnetic component and magnetic components that form the same pole, a respective one Form magnetic component assemblies, the first to N-th rotor modules being arranged in ascending order of their names in the axial direction, with a respective magnetic component belonging to one of the magnetic component assemblies of the first to N-th rotor modules at a graduation angle cn ...
- the invention also relates to an electrical machine.
- Staggered rotors in which a respective pole does not consistently extend straight in the axial direction, are used to reduce cogging torques and a torque wave when operating an electrical machine.
- the document DE 10 2012 205 191 A1 discloses, for example, a rotor with an arrangement of six pole components which are arranged in a layer direction running perpendicular to the direction of rotation. There is an offset between a first pole component and a second pole component as well as between a third pole component and a second pole component. A fourth pole component has no offset with respect to the third pole component. A fifth pole component and a sixth pole component each have an offset in the opposite direction to their predecessor.
- Such a symmetrical V-shaped arrangement makes it possible to compensate for axial forces on the first to third rotor module that arise during the rotating operation of the rotor by almost identical but oppositely oriented axial forces on the fourth to sixth rotor module.
- the axial force can be transmitted to a stator in such a way that a natural frequency of the stator is excited, which is undesirable, especially from the NVH point of view (noise, vibration, harshness - noise, vibration, roughness).
- the invention is therefore based on the object of specifying a possibility for operating an electrical machine which is improved from the NVH point of view.

- a respective staggering angle relates to a predetermined point of a magnetic component, which is the same for all magnetic components. In the case of plate-shaped magnetic components, this can be their center point, for example, on which the angle can be perpendicular.
- the graduation angles ⁇ relate to the magnetic components of the first to (N / 2) -th rotor modules belonging to the magnetic component arrangement. These magnetic components are also referred to below as the first group. Since the graduation angles ⁇ are different from one another, each magnetic component of the first group has a different graduation angle. In other words, no staggering angle occurs more than once in the first group.
- the second group is arranged mirror-symmetrically to the first group with respect to a plane of symmetry which is perpendicular to the axis of the coordinate system and runs between the (N / 2) -th and [(N / 2) +1] -th rotor module is.
- the rotor according to the invention is characterized in that the staggering angle a of at least two of the magnetic components belonging to the magnetic component arrangement is not equal to ao + (M) ß.
- M ao +
- the first group and, because of the mirror-symmetrical arrangement, also the second group have at least one offset in the circumferential direction.
- at least one pair of staggering angles of the first group is interchanged compared to staggering angles of a V-shaped arrangement not according to the invention, in which the magnetic components of the first group are each offset by a fixed angle to the preceding magnetic component. Due to the mirror symmetrical arrangement, you can use the rotor according to the invention from an M,

- alternate north poles or magnetic component arrangements which form a north pole radially on the outside, with south poles or magnetic component arrangements, which form a south pole radially on the outside, in the circumferential direction. Adjacent magnetic component dimensions typically do not overlap.
- the graduation angle ⁇ of at least three of the magnetic components belonging to the magnetic component arrangement is not equal to ao + (M) ß. It is also conceivable that the staggering angle a of all magnetic components belonging to the magnetic component arrangement of the first to (N / 2) th rotor module is not equal to ao + (M) ß.
- the offset angle is positive in the clockwise direction when viewed from an output side of the rotor.

- the axial width of a respective rotor module is at least 5 mm, preferably at least 10 mm, particularly preferably at least 15 mm and / or at most 45 mm, preferably at most 35 mm, particularly preferably at most 30 mm.
- each rotor module has a partial laminated core in which the magnetic components, in particular embedded or surface-mounted, are arranged.
- the laminated core parts typically form a coherent laminated rotor core.
- the rotor can also have a shaft.
- an electrical machine comprising a stator and a rotor according to the invention which is arranged within the stator.

- FIG. 1 shows a second magnetic component arrangement 4b and a sixth magnetic component arrangement 4f, a third, a fourth and a fifth magnetic component arrangement being concealed on one in FIG. 1
- the magnetic components 3a to 3f of the first magnetic component arrangement 4a, the magnetic components of the third magnetic component arrangement and the magnetic components of the fifth magnetic component arrangement each form a north pole here, purely by way of example, radially on the outside, whereas the magnetic components of the second magnetic component arrangement 4b, the magnetic components of the fourth magnetic component arrangement and the Magnet components of the sixth magnet component arrangement 4f each form a south pole radially on the outside.

- Fig. 2 three clockwise positive angles 8, 9, 10 be related to a reference angular position 12 are shown.
- the angle 8 denotes the graduation angles ai, ae, in which the magnetic components 3a and 3f are arranged
- the angle 9 denotes the graduation angles 03, 04, in which the magnetic components 3c, 3d are arranged
- the angle 10 denotes the graduation angles 02, 05, in which the magnetic components 3b, 3e are arranged.
- the graduation angles 03, 04 are larger by an offset angle ⁇ , represented by an angle 11, and the graduation angles 02, 05 by twice the offset angle ⁇ are greater than the graduation angles ai, ab.
- the first three or N / 2 magnetic components 3a, 3b, 3c on one side of the plane of symmetry 13 can also be used as a first group and the last three or N / 2 magnetic components 3d, 3e, 3f on the other side of the plane of symmetry 13 can also be used second group are called.

- 3 is a staggering diagram of the rotor 1 with axial forces drawn in during the rotary operation of the rotor 1.
- a staggering scheme illustrates the positional relationships of the magnetic elements of a magnetic component arrangement representatively for the other magnetic component arrangements in two-dimensional form.
- the offset angle ⁇ and the axial distances between the magnetic components are purely exemplary. Essentially, the staggering scheme is used to qualitatively represent the multiple of the offset angle ⁇ of the individual magnetic components.
- the axial forces acting during rotary operation are shown by arrows 14a, 14b, 15a, 15b.
