Abstract
The invention discloses a solidifying technology for rotor magnetic steels of a permanent magnet motor. The rotor magnetic steels are solidified according to the following steps of: firstly, gluing the magnetic steels on the periphery of the rotor by glue water; then, uniformly spreading the glue water on the external surfaces of the magnetic steels; coating a 0.25mm-thick alkali-free glass tape layer on the external surfaces of the magnetic steels; using a laminated glass cloth plate to scrape away the glue water oozing from a gap of the alkali-free glass tape; and finally, horizontally placing the rotor, and finishing the solidification work at normal temperature. With the magnetic steel solidifying technology of the invention, the magnetic steel dropping failure rate of the produced permanent magnet motor at the speed of 2000r/min is almost zero, and the stability between the magnetic steels and the rotor is enhanced, moreover, a baking device is not needed in the solidifying process, so that much cost on electric power, equipment and the like is saved, and greater economic benefit is brought for production.
Description
Technical field
The present invention relates to a kind of bonding curing process of magnet steel, the rotor magnetic steel curing process on especially a kind of magneto belongs to the rotor magnetic steel curing technology field of motor.
Background technology
In magneto, rotor magnetic pole is that the magnetic links by several watts shape is put together, and with the high strength glue on the cylindrical of rotor.And magneto is in when work, and the rotating speed of its rotor is very high, and the high speed rotating of rotor can produce very big centrifugal force, and bonding unstable magnet steel is easy to come off, and causes mechanical disorder, and has reduced the useful life of motor.In order to address this problem, the people in the industry has also made a lot of effort, has designed the better adhesives of multiple adhesive effect.But, same adhesives, under the technique for sticking condition of different, degree of its bonding back anti-shearing force also can differ greatly, have in addition can differ several times.At present, the technique for sticking that industry generally adopts is, earlier with glue with bonding magnetic steel after, carry out baked and cured again.This bonding curing process, though guaranteed the reliability that magnet steel solidifies, the coming off of magnet steel when having prevented the rotor high-speed running, glue can be thinning in the process of curing; Viscosity can reduce, and often glue can run off from bonding plane after curing end, has dwindled the area of bonding magnetic steel; Effect after the curing is unsatisfactory, and, need be equipped with special baking device when curing; Simultaneously also can consume a large amount of electricity, both increase production cost, the effect of its curing is also bad.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of cost of both having saved, can improve the permanent-magnetic electric machine rotor magnet steel curing process of the bonding steadiness between magnet steel and rotor again.
Technical solution of the present invention is achieved in that a kind of permanent-magnetic electric machine rotor magnet steel curing process, is cured according to following steps,
Preferably, the thickness of said glass cloth laminated sheet is 0.8mm.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Permanent-magnetic electric machine rotor magnet steel curing process of the present invention.Adopted the technology that makes magnet steel and the bonding curing of rotor at normal temperatures; Because its solidification process is under normal temperature condition; The viscosity of glue can not change in solidification process, and glue can not run off yet, and; Outer surface at magnet steel has also wrapped up one deck binding strap, make between magnet steel and the rotor bonding more firmly, reliable.Adopt magnet steel curing process of the present invention; The magneto of producing is under 2000 rev/mins rotating speed; The failure rate that magnet steel comes off is almost nil, has strengthened the steadiness between magnet steel and the rotor, and does not need baking device in the solidification process; Saved costs such as a large amount of electric energy and equipment, brought very big economic benefit to production.
Embodiment
A kind of permanent-magnetic electric machine rotor magnet steel curing process of the present invention is cured according to following steps,
at the outer surface of magnet steel, applies glue equably;
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Permanent-magnetic electric machine rotor magnet steel curing process of the present invention.Adopted the technology that makes magnet steel and the bonding curing of rotor at normal temperatures; Because its solidification process is under normal temperature condition; The viscosity of glue can not change in solidification process, and glue can not run off yet, and; Outer surface at magnet steel has also wrapped up one deck binding strap, make between magnet steel and the rotor bonding more firmly, reliable.Adopt magnet steel curing process of the present invention; The magneto of producing is under 2000 rev/mins rotating speed; The failure rate that magnet steel comes off is almost nil, has strengthened the steadiness between magnet steel and the rotor, and does not need baking device in the solidification process; Saved costs such as a large amount of electric energy and equipment, brought very big economic benefit to production.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
