The motor 1 for compressor of embodiment according to a first aspect of the present invention is described below with reference to Fig. 1-Fig. 3.
As shown in Figure 1-Figure 3, the motor 1 for compressor according to embodiments of the present invention, including stator 11 and rotor 12.
Stator 11 includes stator core 111, and stator core 111 can be formed by multiple stalloys are stacked on top of each other.Stator
11 is hollow ring, has stator hole, rotor 12 is rotatably arranged at stator in the hole inside it.
Rotor 12 includes rotor core 121 and the Magnet 122 being located in rotor core 121, similarly, rotor core 121
Can also be to be formed by multiple stalloys are stacked on top of each other, rotor 12 has rotor hole in the middle part of hollow ring and its, compressor
Bent axle is fixed on rotor in the hole, and together rotates with rotor 12.It is additionally provided with rotor core 121 and run through rotor core 121 upper
Multiple magnet openings of lower section height upwards, Magnet 122 is arranged on Magnet in the hole.
In an embodiment of the present invention, rotor core 121 height dimension in the vertical direction, more than stator core 111
Height dimension in the vertical direction.Further, as shown in figure 1, the top surface of rotor core 121 is higher than stator core 111
Top surface, and the bottom surface of rotor core 121 is less than the bottom surface of stator core 111 that is to say, that being installed in rotor core 121
After in stator core 111, the top surface of the rotor core 121 and bottom surface corresponding end-faces all beyond stator core 111.
Further, the top surface of rotor core 121 be higher than stator core 111 top surface difference in height be H1 that is to say, that
The distance that the top surface of rotor core 121 exceeds the top surface of stator core 111 is H1；The bottom surface of rotor core 121 is less than stator ferrum
The difference in height of the bottom surface of core 111 is H2 that is to say, that the bottom surface distance that the bottom surface of rotor core 121 exceeds stator core 111 is
H2.Wherein in an embodiment of the present invention, H1 is not equal to H2.
Specifically, in prior art, due to the presence of magnetic pull, after rotor is assemblied in stator core, rotor is place
In centered position, that is, keep (ignoring gravity) during balance the distance equal (H1=H2) that rotor stretches out stator core two ends, just
Due to above-mentioned situation, in the prior art, after compressor assembling, rotor and bent axle connect as one, after assembling
If the weight of both rotor bent axles is sufficiently large, whole rotor and bent axle can sink, that is, make crankshaft thrust face and crankcase
Thrust surface pressure between the two increases, and that is, frictional force increases, and the mechanical loss of whole compressor can rise.
Or on the other hand with the development of reciprocating compressor small-sized efficient, rotor part and bent axle more do more
Little, crankcase also more adopts cast iron, sometimes for lifting motor efficiency, by the way of rotor is using installing permanent magnet, and due to turn
When subassembly and crankshaft component weight are too small, after the rotor equipped with permanent magnet assembles within the compressor, rotor and crankcase
Rotor and bent axle can be made between lower end (mainly lower end is near the part of rotor counterbore) to produce and rise due to the effect of captivation
One power upwards, operationally time can make whole bent axle play upwards, easily cause abnormal wear or the stall of compressor.
Just because of this, the motor 1 for compressor according to embodiments of the present invention, by by the height of rotor core 121
Degree is designed to the height higher than stator core 111, and makes the top and bottom of rotor core 121 exceed stator core 111
The distance of top and bottom is different, it is hereby achieved that the magnetic pull of different directions, thus can solve on of the prior art
State problem, that is, this motor 1 can preferably solve the crankshaft thrust face in compressor in prior art and song according to practical situation
Frictional force between axle box thrust surface is larger, and the problem of crankshaft component play upwards.
Below with reference to Fig. 1-Fig. 3, different embodiment according to the subject invention is described.
In one embodiment of the invention, when Magnet 122 is ferrite permanent magnet, H2 ＞ H1.As above-mentioned existing
For the description of technology, after compressor assembling, rotor and bent axle connect as one, if both rotor bent axles after assembling
Weight sufficiently large, then whole rotor and bent axle can sink, that is, make crankshaft thrust face with crankcase thrust surface between the two
Pressure increase, that is, frictional force increases, and the mechanical loss of whole compressor can rise.Therefore in one embodiment of the present of invention
In, when Magnet 122 is ferrite permanent magnet, the weight of rotor 12 will certainly be caused to increase, therefore by the bottom of rotor core 121
The height difference H 2 that face is less than the bottom surface of stator core 111 is designed to exceed stator core 111 more than the top surface of rotor core 121
Top surface apart from H1 that is to say, that when rotor core 121 upper end exceed stator core 111 height be less than rotor 12 lower end surpass
Go out stator core 111 height when, between whole rotor 12 and stator core 111 produce magnetic pull upwards.Therefore, in order to subtract
Friction between small crankshaft thrust surface and crankcase thrust surface, can make H2 ＞ H1 when compressor assembles, when both sizes set
Meter reasonable when so that being in approximate micro- contact condition between crankshaft thrust face and crankcase thrust surface, thus reducing two
Friction between person.
Generally in that case, in order to obtain preferable effect, need to make H1 and H2 meet following relational expression：2mm≤
H2-H1≤7mm, and 2mm≤H1+H2≤12mm.That is, the bottom surface of rotor core 121 is less than the distance of the bottom surface of stator core 111
H2 is 2mm～7mm with the top surface of rotor core 121 beyond the difference apart from H1 of the top surface of stator core 111.As shown in Fig. 2
Rotor core 121 height Hx exceeds 2mm～12mm compared with stator core 111 height Hy.
In another embodiment of the present invention, when Magnet 122 is rare-earth permanent magnet, H1 ＞ H2.As above-mentioned existing skill
In the description of art, due to rotor part and crankshaft component weight too small when, when the rotor equipped with permanent magnet assembles within the compressor
Afterwards, can be made due to the effect of captivation between the lower end (mainly lower end is near the part of rotor counterbore) of rotor and crankcase
Obtain rotor and bent axle produces and rises a power upwards, operationally time can make whole bent axle play upwards, easily causes compressor
Abnormal wear or stall.For this reason, when Magnet 122 is rare-earth permanent magnet, the weight of rotor 12 reduces, therefore by rotor core
121 top surface is designed to be less than stator core more than the bottom surface of rotor core 121 apart from H1 beyond the top surface of stator core 111
The height difference H 2 of 111 bottom surface exceeds the height of stator core 111 less than rotor core 121 that is to say, that working as rotor 12 lower end
When upper end exceeds the height of stator core 111, the magnetic pull producing between whole rotor 12 and stator core 111 is downward, so,
The pulling force between rotor 12 and crankcase can be balanced due to the presence of downward magnetic pull.Usual Magnet 122 in such cases
Magnetic force stronger, in order to cost performance is considered, need not by rotor core 121 do to exceed stator core 111 too many, as shown in Fig. 2
Generally now rotor core 121 height Hx is 1mm～5mm, i.e. 1mm≤H1+H2≤5mm compared with stator core 111 height Hy.
Additionally, in an embodiment of the present invention, the height of rotor core 121 is more than the height of Magnet 122.Specifically,
The height of rotor core 121 is less than or equal to 2.5mm with the difference of the height of Magnet 122.The structure of rotor 12 thus can be made
More reasonable.After rotor 12 is installed in stator 11, can be produced corresponding and effective according to the above embodiments description
Magnetic pull.
And currently in order to reducing crankshaft thrust face and the friction between the two of crankcase thrust surface, can be in crankshaft thrust
The mode of retainer (band ball) is installed between face and crankcase thrust surface, therefore between crankshaft thrust face and crankcase thrust surface
Frictional force can greatly reduce further.
It is further to note that during assembling, needing the magnetic pull that rotor 12 is produced with stator core 111 specifically upwards
Or downwards, with the weight of rotor 12 itself and the weight of bent axle, and the close phase of remanent magnetism situation of the Magnet 122 in rotor 12
Close.
Below with reference to Fig. 1, compressor 100 according to embodiments of the present invention is described.As shown in figure 1, according to embodiments of the present invention
Compressor 100, including：Crankcase 2, motor 1 and bent axle 3.
The top of crankcase 2 has crankcase thrust surface 21, and bent axle 3 has crankshaft thrust face 31, crankshaft thrust face 31
Above crankcase thrust surface 21.Motor 1 is located at below crankcase 2, and bent axle 3 is located in the rotor 12 of motor 1.
Due to the motor 1 for compressor 100 according to embodiments of the present invention have the advantages that above-mentioned, therefore pass through setting
Motor 1 according to embodiments of the present invention, such that it is able to make compressor 100 also have corresponding advantage, implements according to the present invention
The compressor 100 of example, it is larger to solve the frictional force between crankshaft thrust face 31 and crankcase thrust surface 21 in prior art,
And the problem of bent axle 3 part play upwards.
