The present invention is at making in such cases.
[summary of the invention]
High-power high speed rotor of permanent-magnetic power generator magnet the present invention seeks to overcome deficiency of the prior art and a kind of magnet assembly installation method that the ndfeb magnet of big quality can be fixed on the high speed permanent magnet generator runner hub is provided, so that can provide enough magnetic field intensity and fixed magnets to overcome centrifugal force and unilateral magnetic force.Simultaneously can easily magnetic pole be made the oblique utmost point, to change the pole embrace of magnetic pole, reduce the influence of cogging torque, reduce the detent torque of generator.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:
A kind of magnet assembly installation method of magneto is characterized in that including as follows
Step is poly-:
At first, magnet is placed on the magnet base, makes the periphery of magnet aim at periphery on the magnet susceptor surface;
Secondly, the magnet over cap of non-magnet material is inserted in magnet, makes the magnet over cap cover magnet fully, utilize hold-down screw to pass the magnet over cap and be screwed on the magnet base, magnet is fixed on the magnet base;
Its three, couple together between magnet over cap and the magnet base, magnet over cap and magnet base are connected as a single entity;
They are four years old; the fixing screw hole of hiding that when the side of magnet over cap is provided with a plurality of magnet over caps and connects together successively, is used for hiding the hold-down screw cap; on the magnet base with hide the fixing screw hole corresponding section and also be provided with counterbore; also some places counterbore to the hold-down screw cap; arrive this, finish magnet assembly and install.
The magnet assembly installation method of aforesaid a kind of magneto, it is characterized in that described magnet over cap and magnet base are connected as a single entity be adopt welding or bonding process.
The magnet assembly installation method of aforesaid a kind of magneto is characterized in that described magnet is neodymium iron boron magnetic body.
The magnet assembly installation method of aforesaid a kind of magneto is characterized in that being coated with the anti-corrosion protection lacquer at its outer surface after finishing the magnet assembly installation, and assembly is formed protective layer.
The present invention compared with prior art has following advantage:
The present invention utilizes the magnet over cap that magnet is fixed on method on the magnet base, and it can provide enough magnetic field intensity and fixed magnets to overcome centrifugal force and unilateral magnetic force well.
Handy this method can be made magnetic pole the oblique utmost point easily simultaneously, to change the pole embrace of magnetic pole, reduces the influence of cogging torque, reduces the detent torque of generator.
