Definitions
- the invention relates to a transverse flux machine according to the preamble of claim 1 and a method for producing such a machine.
- the rotor of known permanently excited transverse flux machines has a large number of hard and soft magnetic segments, the prefabrication and assembly of which is complex.
- the delicate structure increases the manufacturing effort, especially if, despite the high magnetic forces, a vibration-free structure is to be achieved.
- the invention is therefore based on the object of further developing a permanently excited transverse flux machine and a method for its manufacture in such a way that a stable machine structure is achieved with little expenditure on material and manufacture.
- the magnetic flux generated by a permanent magnet segment alternately flows through the soft magnetic bodies of two conductor rings of a transverse flux machine arranged on different sides of the magnet, the direction of flow in the magnet coinciding with the direction of flow in the two air gaps through which it flows.
- the magnetic segments are preferably arranged between two U-shaped halves of a square wound core of the cutting tape and the stator cores are also prefabricated as U-shaped cutting cores made of grain-oriented material.
- the entire machine structure is characterized by a few different, simply designed and prefabricated components, a high stability in the magnetic active machine volume being ensured with little effort, in particular with respect to the fluctuating air gap forces.
- FIG. 1 shows the longitudinal section of a three-phase, permanently excited transverse flux machine as an internal rotor with a radial air gap flow
- FIG. 2 shows cross sections corresponding to lines I - I and II - II of the 24-pole transverse flux machine from FIG. 1;
- the transverse flux machine 1 shown in FIG. 1 has three identical rotor disks 2 in which permanent magnets 3 are integrated, the magnets forming only one ring per phase and the direction of the flux in the magnet and in the air gap 4 being the same.
- the magnets 3 are arranged between two U-shaped, soft-magnetic rotor bodies 5 which concentrate the flux, so that the flux density in the air gap is significantly higher than in the magnets.
- the magnetic circuit generated by a magnet 3 is alternately closed when the rotor is rotated by a U-shaped soft magnetic stator body 6 arranged axially to the left and right of the rotor disk 2.
- stator bodies 6 there are conductor rings 7 made of profiled wire which run in the circumferential direction.
- the magnetic forces acting radially in the two air gaps 4 of a magnetic circuit are compensated for by the two-air gap arrangement.
- Radial oscillation of the ends of the soft magnetic stator body 5 is prevented by a stable design of the conductor ring 7 and by a rigid reinforcing plate 8.
- a band bearing ring 9 arranged in the middle part of the radially outer rotor body 5 absorbs the radially effective forces.
- the soft and hard magnetic parts 3, 5 of the rotor disk 2 are bonded to one another, with axially attached ring disks 10 ensuring the mechanical stability and encapsulation of the magnet 3 against environmental influences.
- the magnetically passive stator part consists of four identical inner housing elements 12 and two identical motor shields 13.
- the identical rotor disks 2 are mounted on a square shaft 14.
- Ball bearings 15 are arranged at the axially outer ends and roller bearings 16 prevent radial vibrations between the rotor disks.
- FIG. 2 shows cross sections according to section lines I - I and II - ⁇ from FIG. 1.
- Both 24-pole stator halves 17a, b are identical in construction and only offset from one another in the circumferential direction by one pole pitch.
- the number of stator bodies 6 per half of the stator corresponds to half the number of rotor poles.
- the transverse flux machine 20 shown in FIG. 3 with an axial air gap is recommended.
- the magnetic circuit arrangement from FIG. 1 is rotated through 90 °, the advantageous material utilization and the low component expenditure being retained.
- the stator 21 preferably consists of two identical halves 21a, b, which in turn have two different, die-cast stator shells 22, 23.
- the U-shaped, soft-magnetic stator bodies 24 here also preferably consist of two cut core parts 25, 26, the stator body parts 25 fastened in the inner stator shells 22 before the rotor rings 28 prefabricated from the permanent magnets 27 and U-shaped, soft-magnetic rotor bodies 28 are axially fastened 29 can be positioned.
- the outer stator shells 23 equipped with the remaining stator body parts 26 are then pushed axially with the bearings 30.
- the magnets 27 can be designed in block form.
- the surfaces facing the air gap 31 now do not have to be reground.
- the conductor rings 33 prefabricated from a flat conductor strip 32 can be mounted together with their reinforcing sleeve 34 arranged on the air gap side.
- the T-shaped rotor disk 35 can also be prefabricated from several parts.
