Definitions

  • the invention relates to a rotor for a permanently magnetically excited electrical machine according to the preamble of the main claim.
  • a rotor is known for example from DE-OS 2 64 1 536, where the magnet segments are arranged within a cup-shaped flywheel and are held by annular clamping elements.
  • the magnets can also be fixed by an adhesive between the inner surface of the flywheel and the outer surface of the magnets. Such an arrangement is complex and expensive to manufacture.
  • the rotor according to the invention with the characterizing features of the main claim has the advantage that the structure of the entire machine is particularly simple and inexpensive without disadvantageous increase in magnetic resistance in the entire magnetic circuit.
  • the air gap is practically not enlarged by the proposed design, so that there is a reliable and economical overall arrangement with a small magnetic air gap and relatively large permissible tolerances for the manufacture of the magnets.
  • the magnet segments are not attached to the iron carrier with absolute rigidity but with little elasticity, so that the moments that occur are absorbed by centrifugal force and acceleration as well as the thermal stresses without impairing the adhesion of the magnets.
  • the circumference of the magnetic segments is wrapped with a bandage which is impregnated with a magnetizable material, in particular with a magnetizable adhesive.
  • this permanent magnet powder is added, which e.g. during the grinding process of the magnets.
  • An overall arrangement with a particularly high degree of space utilization arises from the fact that the magnetic segments e directly adjoin one another over the entire circumference of the iron are arranged carrier.
  • the narrow gaps between the individual magnet segments caused by manufacturing tolerances can additionally be filled with the same magnetizable adhesive which can also be used for gluing the segments.
  • this adhesive can also be used to fill in the depressions caused by bevelling of the magnetic edges due to production. This gives a practically homogeneous, magnetizable surface of the rotor.
  • a particularly advantageous design option of a rotor for a permanent magnet excited machine also results regardless of the features mentioned above in that the magnet segments are magnetized obliquely to the motor axis direction.
  • the magnetization can take place obliquely across the boundaries of the individual magnetic segments.
  • FIG. 1 shows a plan view of a rotor provided with a bandage
  • FIG. 2 shows a plan view of an obliquely magnetized rotor
  • FIG. 3 shows a partial step through the reactor in the region of two adjacent magnet segments. Description of the embodiments
  • FIG. 1 shows a rotor 10 of a permanently magnetically excited electrical machine, with a shaft 11 on which an iron carrier 12 designed as a soft iron mandrel sits.
  • the rotor is designed for a brushless, electronically controlled synchronous motor.
  • Magnetic segments 13 are fastened to the circumference of the soft iron dome by means of a bandage 14, which can either serve as the only fastening means or as an additional fastening means for an adhesive connection between the magnetic segments 13 and the soft iron mandrel 12.
  • a two-component adhesive, to which permanent magnet powder is added, is used as the adhesive, so that the adhesive area can also be magnetized.
  • Figure 2 shows the hoter without the bandage 1 4 in a special design, in which the individual magnet segments 13 abut each other without visible joints and are magnetized at an angle to the rotor axis direction.
  • the various magnetic areas are designated II and S in accordance with the corundum south poles formed.
  • Figure 3 shows an enlarged view of the gluing between the soft iron mandrel 12 and the magnet segments 13 on the one hand and the filling of the gaps between the magnet segments 13 with the magnetizable adhesive 15. Furthermore, the depressions 16 formed on the magnetic edges are also filled with the magnetizable adhesive . These recesses 16 are production-related due to the so-called chamfering of the magnetic edges, which are bevels which facilitate the pressing of the magnetic segments.
  • the measures according to the invention make it possible to construct a rotor for brushless motors of higher output in a particularly simple manner and with low magnetic losses, the problem of the magnet attachment having been solved without any significant magnetic losses.
  • the bandage 14 According to the use of the bandage 14 according to the invention, the air gap in the motor is practically not enlarged because the bandage is impregnated with the magnetizable adhesive and can therefore be counted as a magnetically active part.
  • the bandage 14 represents a magnetizable support on the magnetic segments, ie that the air gap is influenced only marginally in this type of magnetic attachment.
  • the magnetizable adhesive is expediently allowed to harden in a magnetic field 17 in order to achieve a certain anisotropy of the powder and thus an increase in flow.
  • the magnetizable adhesive 15 is cured in an alignment field 17 indicated in FIG. 3, which is generated in a very simple and advantageous manner by a two-pole magnetization of the overall arrangement. After the magnetizable adhesive 15 has hardened, the final magnetization takes place, for example in the manner shown in FIG.
  • magnetizable adhesive 15 brings the already mentioned further significant advantage that larger tolerances can be allowed in the manufacture of the magnetic segments, which considerably reduces the amount of rejects during manufacture and the manufacturing costs. Without these permissible tolerances, the magnets would have to be made approximately with zero tolerance if they were to fit perfectly against the circumference of the iron mandrel 12. Since in the area of the gap between the magnet segments 13 also the production-related. Wells 1o lie, both malfunctions of the magnetic circuit can be eliminated together by filling the magnetic adhesive 15. The entire magnetic body is thus homogeneous. and no longer has any axial magnetic differences. If the magnetizable adhesive 15 is also used to glue the magnetic segments 13 onto the soft iron mandrel 12, additional air gaps in the magnetic circuit can be completely avoided, which leads to a substantial flow height

Abstract

Le rotor pour une machine electrique a aimants permanents, sans collecteur, comprend un nombre donne de segments magnetiques (13) retenus sur un corps tournant (12) en materiau magnetique doux. La fixation des segments magnetiques (13) sur le pourtour du corps tournant en fer (12), est obtenue sans augmentation de l'entrefer magnetique, par des moyens de collage et/ou de retenue magnetisables. Ainsi, les segments magnetiques (13) peuvent etre soit colles sur un noyau en fer doux (12) a l'aide d'une colle magnetisable (15), soit uniquement ou additionnellement, retenus par un bandage (14) qui est egalement impregne d'une substance magnetisable, en particulier de la meme colle magnetisable (15).
