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, relate in particular to a kind of ultrahigh speed permanent magnet motor stator and rotor and install method.
Background technology
Because the air gap of ultrahigh speed permagnetic synchronous motor is little, and rotor banding magnetic, rotor and stator install process in both are very easily attached together, once absorption, be difficult to separated, therefore, in traditional assembling process, conventionally by installer's experience, avoid the absorption of rotor and stator, often both processes that installs are carried out slowly, inefficiency, and careless slightly will being attached together, reliability is lower.
Summary of the invention
Based on this, for above-mentioned technical problem, provide a kind of ultrahigh speed permanent magnet motor stator and rotor to install method.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
Ultrahigh speed permanent magnet motor stator and rotor installs a method, comprises the following steps:
In a concentric turns of end cap, offer a plurality of perforates equidistant with end cap axle center being positioned at, described concentric turns is axially corresponding with the air gap of rotor;
Above-mentioned end cap is installed respectively at two ends at armature spindle;
Non-magnetic stainless steel filler strip is penetrated in the perforate of armature spindle one end end cap, and pass from the corresponding perforate of other end end cap;
Rotor is installed into stator;
Non-magnetic stainless steel filler strip is extracted out;
Cover plate is installed in axial outside at 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.
A kind of ultrahigh speed permanent magnet motor stator and rotor of the present invention installs method by intert non-magnetic stainless steel filler strip at both sides end cap, makes stator and rotor can, because magnetic is attached together, not improve efficiency of assembling and the reliability of motor in the process installing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated:
Fig. 1 is the flow chart that a kind of ultrahigh speed permanent magnet motor stator and rotor of the present invention installs method;
Fig. 2 is the structural representation of end cap of the present invention.
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, on a concentric turns A of end cap 100, offer a plurality of perforates 110 equidistant with end cap axle center being positioned at.
Wherein, concentric turns is axially corresponding with the air gap of rotor, i.e. the position of perforate 110 is to be axially corresponding with the position of air gap.
It is upper that 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, at the two ends of armature spindle, above-mentioned end cap 100 is installed respectively.
S130, non-magnetic stainless steel filler strip is penetrated in the perforate 110 of armature spindle one end end cap 100, and pass from the corresponding perforate 110 of other end end cap 100.
When perforate 110 is four, the quantity of corresponding non-magnetic stainless steel filler strip is also four.
Wherein, the thickness of non-magnetic stainless steel filler strip is 2mm, and width is 8mm.
S140, rotor is installed into stator.
The position of above-mentioned perforate 110 with the position of air gap axial corresponding, rotor is being installed after stator, non-magnetic stainless steel filler strip is the gap position in rotor just in time, due to stopping of non-magnetic stainless steel filler strip, rotor and stator can not be adsorbed onto because of magnetic together, thereby affect the assembling of motor, improved efficiency of assembling and the reliability of motor.
S150, non-magnetic stainless steel filler strip is extracted out.
S160, in the axial outside of end cap, cover plate is installed, to seal perforate 110.
Ultrahigh speed permagnetic synchronous motor rotating speed generally can reach 6500r/min.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claims of the present invention.
