Abstract
The invention provides a stator and rotor penetrating method for an ultra-high-speed permanent magnet motor. The method includes the following steps that a plurality of open holes are formed in the concentric circle of each end cover, wherein the distances between the open holes and the axis of the corresponding end cover are equal, and the concentric circle corresponds to an air gap between a stator and a rotor in the axial direction; the end covers are installed at the two ends of a rotor shaft respectively; permeability-free stainless steel filler strips penetrate into the open holes in the end cover at one end of the rotor shaft and penetrate out of the corresponding open holes in the end cover at the other end of the rotor shaft; the rotor penetrates into the stator; the permeability-free stainless steel filler strips are drawn out; cover plates are installed on the axial outer sides of the end covers so as to seal the open holes. According to the stator and rotor penetrating method for the ultra-high-speed permanent magnet motor, the permeability-free stainless steel filler strips penetrate into the end covers on the two sides, the stator and the rotor cannot be attracted together due to magnetism in the penetrating process, and therefore assembly efficiency and reliability of the motor are improved.
Description
Technical field
The invention belongs to machine field, more particularly, to a kind of ultrahigh speed permanent magnet motor stator and rotor installs method.
Background technology
Because the air gap of ultrahigh speed permagnetic synchronous motor is little, and rotor carrying magnetic, during the installing of rotor and stator
Both are easily attached together, once absorption, are difficult to separate, and therefore, in traditional assembling process, generally pass through erector
Avoiding the absorption of rotor and stator, often both processes that installs carry out slowly the experience of people, inefficiency, and careless slightly
Will be attached together, reliability is relatively low.
Content of the invention
Based on this, for above-mentioned technical problem, a kind of ultrahigh speed permanent magnet motor stator and rotor is provided to install method.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that：
A kind of ultrahigh speed permanent magnet motor stator and rotor installs method, comprises the following steps：
Multiple perforates equidistant with end cap axle center are opened up on concentric turns of end cap, described concentric turns axially with
The air gap of rotor is corresponding；
It is respectively mounted above-mentioned end cap at the two ends of armature spindle；
Non-magnetic stainless steel filler strip is penetrated in the perforate of armature spindle one end end cap, and the corresponding perforate from other end end cap
Pass；
Rotor is installed into stator；
Non-magnetic stainless steel filler strip is extracted out；
In the axially external installation cover plate of end cap, to seal perforate.
Described perforate is four, and is evenly arranged in described concentric turns.
Described perforate is bar hole.
The thickness of described non-magnetic stainless steel filler strip is 2mm, and width is 8mm.
It is non-magnetic stainless by interting in both sides end cap that a kind of present invention ultrahigh speed permanent magnet motor stator and rotor installs method
Steel filler strip, makes stator and rotor will not be attached together because of magnetic during installing, improves the efficiency of assembling of motor
And reliability.
Brief description
The present invention is described in detail with reference to the accompanying drawings and detailed description：
Fig. 1 is a kind of ultrahigh speed permanent magnet motor stator and rotor flow chart of installing method of the present invention；
Fig. 2 is the structural representation of the end cap of the present invention.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of ultrahigh speed permanent magnet motor stator and rotor installs method, comprises the following steps：
S110, multiple perforates 110 equidistant with end cap axle center are being opened up on concentric turns A of end cap 100.
Wherein, concentric turns are corresponding with the air gap of rotor in axial direction, and that is, the position of perforate 110 is to exist with the position of air gap
It is axially corresponding.
Perforate 110 is evenly arranged in above-mentioned concentric turns A, and quantity can be four, is certainly not limited to four.
The shape of perforate 110 can be bar hole.
S120, it is respectively mounted above-mentioned end cap 100 at the two ends of armature spindle.
S130, non-magnetic stainless steel filler strip is penetrated in the perforate 110 of armature spindle one end end cap 100, and from other end end
The corresponding perforate 110 of lid 100 passes.
When perforate 110 is four, the quantity of non-magnetic stainless steel filler strip is also four accordingly.
Wherein, the thickness of non-magnetic stainless steel filler strip is 2mm, and width is 8mm.
S140, rotor is installed into stator.
The above-mentioned position of perforate 110 and the position of air gap axial corresponding, after rotor is installed stator, non-magnetic not
Rust steel filler strip can be exactly in the gap position of rotor, due to stop, rotor and the stator of non-magnetic stainless steel filler strip
Will not being adsorbed onto together because of magnetic, thus affecting the assembling of motor, improve efficiency of assembling and the reliability of motor.
S150, by non-magnetic stainless steel filler strip extract out.
S160, end cap axially external installation cover plate, to seal perforate 110.
Ultrahigh speed permagnetic synchronous motor rotating speed typically can reach 6500r/min.
But, those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to explanation originally
Invention, and it is not used as limitation of the invention, as long as in the spirit of the present invention, to embodiment described above
Change, modification all will fall in the range of claims of the present invention.
