Abstract
The invention relates to a rotor of a permanent magnet servo motor and a manufacture method thereof, which aims at providing a rotor of a permanent magnet servomotor that has small protection layer and generates no eddy-current loss. The rotor of a permanent magnet servo motor comprises a rotor iron core, and a magnet shoe attached to the outer circle of the rotor iron core, wherein inner epoxy glue is coated to the outer circle of the magnet shoe; a glass fiber tape is uniformly wound on the outer circle of the epoxy glue; and outer epoxy glue is coated on the outer circle of the glass fiber tape. Carbon fiber materials and stainless steel materials are replaced by using the glass fiber tape so that the thickness of the protection sleeve on the outer circle of the magnet shoe is within 0.4mm and even 0.2mm, thus the performance of the servo motor is improved. The rotor is also easily machined so as to reduce the manufacture cost.
Description
Technical field
The present invention relates to field of motor manufacturing, in particular, the invention relates to a kind of permanent magnetic servo motor rotor and the manufacturing approach that reduce the servo motor rotor outer layer thickness.
Background technology
At present, servo motor rotor generally adopts the carbon fiber sleeve pipe to press-fit with stainless steel outer sleeve to press-fit, but the two is influenced by moulding process; Can't reach minimum wall thickness; Generally all at 0.4 ~ 0.5mm, and the servomotor air gap is very little, does not allow the magnetic shoe overcoat thickness to surpass 0.4mm.And, motor also has eddy current loss when moving on the stainless steel outer sleeve, the moulding external diameter of the two and highly also suffering restraints simultaneously.
Patent Office of the People's Republic of China discloses a CN2112900U document on August 12nd, 1992; Name is called the rare-earth permanent magnet element that is used for rotor, and outer shroud is bonding constitutes for the thin-walled protection that the magnetic that these parts are circular bases of being processed by the high magnetic conduction rigid material of the usefulness that is positioned at nexine, make with neodymium iron boron or samarium cobalt rare earth permanent magnet material, the interpolar packing material made from epoxy resin tubing class non-magnet material and outermost layer are processed with high-strength material.The shortcoming of these parts is that its outermost layer guard ring adopts stainless steel material or carbon fibre material to constitute, and its thickness is thicker, when using stainless steel material, also can produce eddy current loss.
Summary of the invention
The present invention is thicker and be easy to generate the shortcoming of eddy current loss for solving the permanent magnet outer protection cover thickness that exists in the prior art, provides a kind of protective layer thickness the very little permanent magnetic servo motor rotor and the manufacturing approach that can't produce eddy current loss.
The technical solution adopted for the present invention to solve the technical problems is: the present invention includes rotor core, be attached to the magnetic shoe of rotor core outer ring; Apply the internal layer epoxide-resin glue in the magnetic shoe outer ring; The uniform winding glass fiber tape in the epoxide-resin glue outer ring applies outer epoxide-resin glue in the glass fiber tape outer ring.Epoxy resin has good thermal conductivity, electric insulating quality, thermal endurance, and solidifies back good mechanical strength and machinability; While, the thickness of glass fiber tape was also more and more thinner along with the glass fiber production technology improves constantly, and thickness can reach 0.08mm, also has high mechanical strength simultaneously; Apply layer of epoxy glue earlier in the magnetic shoe outer ring, carry out colligation with glass fiber tape again, general colligation layer 2-3; Magnetic shoe is firmly fixing; Apply layer of epoxy glue again in the glass fiber tape outer ring, epoxide-resin glue can be penetrated in the glass fiber tape, carries out machine work again rotor profile is worked into given size; The thickness that can guarantee the whole protecting layer like this is no more than in the 0.4mm scope, and has stopped the generation of eddy current.
As preferably, internal layer epoxide-resin glue thickness is less than 0.1mm.0.1mm its adhesion of thick epoxide-resin glue is enough.
As preferably, outer epoxide-resin glue thickness is less than 0.1mm.0.1mm its adhesion of thick epoxide-resin glue is enough.
As preferably, the glass fiber tape thickness is in the 0.1-0.2mm scope.Because outer epoxide-resin glue has been penetrated in the glass fiber tape, when carrying out outer machine work, as long as guarantee have the colligation of layer of glass band to live magnetic shoe, so the glass fiber tape thickness is in the 0.1-0.2mm scope.
A kind of manufacturing approach of permanent magnetic servo motor rotor may further comprise the steps:
A. after magnetic shoe was sticked in the rotor core outside, brushwork epoxy resin glue made epoxide-resin glue fill up the space between each magnetic shoe, and wraps all magnetic shoes;
B. in the magnetic shoe outside of having wrapped up epoxide-resin glue with glass fiber tape uniform winding layer 2-3;
C. the brushwork epoxy resin glue or be immersed in the epoxide-resin glue repeatedly again in glass fiber tape outside is penetrated in the glass fiber tape epoxide-resin glue, until said triplex glass fabric strip fully by the epoxy resin glue penetration and be bonded together;
D. placed 4 hours, and after said epoxide-resin glue full solidification, the rotor outer ring was machined, have the layer of glass band intactly keeping as long as machine the back by the figure paper size.
The purpose of the epoxide-resin glue of brushing ground floor is that magnetic shoe and rotor core are bonded together basically; Twine layer 2-3 with very thin glass fiber tape, be evenly, to be wrapped in the magnetic shoe outside for the fiber that makes glass fiber with having levels; Be penetrated in the glass fiber tape with epoxide-resin glue again, each layer glass fiber tape be bonded together each other form integral body together; After the epoxide-resin glue full solidification, machine again, the overall dimension of rotor is worked into given size, glass layer at this moment is an integral body, and good fiber level is arranged again; As long as after machining, also have the layer of glass band intactly keeping, promptly guarantee to have the complete glass layer of one deck to be wrapped in the magnetic shoe outside; So just make under the very thin situation of insulation and the fixed bed of magnetic shoe, guaranteed the constant intensity of magnetic shoe; Given full play to glass fiber tape and epoxide-resin glue advantage separately.
The invention has the beneficial effects as follows: substitute carbon fibre material and stainless steel material with glass fiber tape, make the outer field protective sleeve thickness of magnetic shoe in 0.4mm, even can reach within the 0.2mm, improved the performance of servomotor; And easy to process, reduced manufacturing cost.
