- the rotor core sections 27, 28 may be glued together.

Accordingly, the Statornuten 15 for reducing the Nutrastens each having a corresponding slope 21, so that the Statornuten 15 extend over its entire axial length in both the axial and in the circumferential direction of the stator 11. In this case, the magnet segments 18 of the rotor 12 would have no skew 21.
- FIG. 8 shows a coil winding 16 for avoiding grooving. This can be used as an alternative to the preceding embodiments. After that, the coil winding 16 is ironless. According to the present embodiment shown in FIG. 8, the coil winding 16 has a self-supporting winding. Accordingly, the coil winding 16 according to the present embodiment shown in Figure 8 does not require a support element, such as the mentioned in the preceding embodiments stator 11. Alternatively, the coil winding 16 may be supported in a presently not shown embodiment but also by a radially outer return ring.
- the permanent magnet motor 9 shows an end view of the permanent magnet motor 9 in a greatly simplified representation according to a further exemplary embodiment.
- the permanent magnet motor 9 again comprises a radially inner rotor 12, which is rotatably mounted about the rotation axis 13. Furthermore, the permanent magnet motor 9 comprises the radially outer stator 11.
- the stator 11 has a plurality of stator slots 15 in the circumferential direction, of which only one is provided with a reference numeral for reasons of clarity.
- the stator slots 15 extend in the axial direction of the perma nentmagnetmotors 9.
- the permanent magnet motor 9 comprises coil windings 16.
- a coil winding 16 forms at least one coil. The coil winding is received in the stator 15 over the entire circumference of the stator 11 distributed.
- the rotor 12 includes a rotor core 17 and a plurality of magnet segments 18.
- the magnet segments 18 are supported by the rotor core 17. Furthermore, the magnet segments 18 are distributed over the entire circumference of the rotor core 17.
- the magnet segments 18 extend in the axial direction of the permanent magnet motor 9.
- a recess in the form of a groove 29, which extends essentially in the axial direction, is formed on the stator 11 per coil winding 16. The groove 29 helps to increase an effective magnetic air gap between the stator 11 and the rotor 12, thereby reducing the nutastast magnetic interaction between the stator 11 and the rotor 12.
- FIG. 10 shows a permanent magnet motor 9, which in many aspects is similar to the permanent magnet motor explained with reference to FIG. 9. To avoid repetition, reference is therefore made to the statements there.
- the permanent magnet motor according to FIG. 10 has two slots 29 per coil winding 16 which extend essentially in the axial direction. The above-described effect of reducing the groove can be further increased by the presence of two grooves.
