The upper end ring 2 comprises a base plate 21 and a guide plate 22, an inner hole 211 is formed in the base plate 21 and is communicated with the shaft hole 11 through the inner hole 211, and the guide plate 22 is arranged on one side, away from the inner core 1, of the base plate 21, so that in the working process of the rotor, the guide effect is achieved by means of the guide plate 22. Specifically, the deflector 22 can promote the whole rotor to inhale from the outside of the inner core 1 in the process of rotating along with the inner core 1, so as to promote the refrigerant in the motor to flow from the outside of the inner core 1 to the shaft hole 11 in the middle of the inner core 1 along the radial direction of the inner core 1, thereby completing the cooling work of the stator winding matched with the rotor under the action of the refrigerant and improving the service life and the working efficiency of the stator winding.
Specifically, the inner core 1 may be formed of metal iron, in order to enable the rotor to work normally, as shown in fig. 2, a plurality of slots 12 are further provided on the inner core 1, the plurality of slots 12 are uniformly distributed along the axial direction around the inner core 1, a plurality of aluminum strips 3 are correspondingly provided in the slots 12, and the number of the slots 12 and the aluminum strips 3 can be flexibly selected according to the actual requirement of the compressor motor; the base plate 21 is made of metal aluminum, is fixedly connected with the inner core 1, and can be attached to the end face of the inner core 1 for improving the structural stability of the rotor; correspondingly, as shown in fig. 1, the other end face of the inner core 1 along the axial direction of the inner core can be further provided with a lower end ring 4, the lower end ring 4 is fixedly connected to one end of the inner core 1, which is away from the upper end ring 2, and the lower end ring 4 is connected with a plurality of aluminum strips 3 arranged in a plurality of slots 12 to form a closed cage-shaped conductor, so that the rotor can generate effective induction current in an alternating magnetic field, a rotor magnetic field is formed, and the rotor magnetic field interacts with a stator magnetic field, and the purpose of driving the motor to operate is achieved. In order to improve the processing efficiency of the rotor, preferably, the baffle 22 may also be made of metal aluminum, and may be formed with the base plate 21 in an integrally formed manner, which may further improve the connection reliability between the baffle 22 and the base plate 21, ensure that the baffle 22 can generate a reliable flow guiding effect in the working process of the rotor, and the baffle 22 may be in a spiral structure, the rotation direction of which may be determined according to the actual working condition of the rotor, and only need to ensure that the baffle 22 can guide the fluid outside the rotor (or the inner core 1) to the position where the shaft hole 11 is located along the radial direction of the inner core 1 in the normal working process of the rotor, for example, the rotor rotates in the clockwise direction, so that the rotation direction of the baffle 22 may also be set clockwise, and a person skilled in the art may determine the rotation direction of the baffle 22 according to the actual condition. The baffle 22 may have a flared spiral structure, and the baffle 22 may have a continuous structure or a structure in which a plurality of stages are spaced apart from each other.
In order to further improve the guiding effect of the baffle 22 on the fluid, preferably, the baffle 22 may extend from the inner side of the base plate 21 to the outer side of the base plate 21 in a spiral manner, and the fluid may be directly guided from the outer side wall of the inner core 1 to the position of the shaft hole 11 through the restriction and the guiding effect of the baffle 22, so as to further improve the order and the purpose of the fluid in the flowing process, and further improve the rate and the flow of the refrigerant guided from the outer side of the inner core 1 to the position of the shaft hole 11 along the radial direction of the inner core 1 under the action of the baffle 22, so as to further improve the cooling effect on the stator winding.
In order to improve the flow guiding effect of the flow guiding plate 22, preferably, the cross section of the flow guiding surface of the flow guiding plate 22 is in an involute structure, when the flow guiding plate 22 extends along the axial direction of the inner core 1, the top view of the flow guiding plate 22 is a schematic cross section of the flow guiding plate 22, that is, as shown in fig. 4, when the cross section of the flow guiding surface is in an involute structure, smoothness and continuity of fluid flowing along the flow guiding plate 22 can be improved to a certain extent, so as to further improve the guiding effect of the flow guiding plate 22 on the fluid.
In addition, in order to prevent the rotor from rotating unstably due to the unequal centrifugal forces generated at different parts of the baffle 22 caused by the different dimensions of the baffle 22 in the axial direction of the core 1 during the operation of the rotor, it is preferable that the dimensions of the baffle 22 in the axial direction of the core 1 are equal, such as the baffleThe thickness at any position on 22 is h1. Specifically, the cross-section of the flow-guiding surface of the flow-guiding plate 22 may be made to conform to the following involute equation: x is x 1 ＝(r 1 +(r 2 -r 1 -1.5h 1 )*t)*cos(360*t)，y 1 ＝-(r 1 +(r 2 -r 1 -1.5h 1 ) T) sin (360 t), wherein r 1 Is the inner diameter of the substrate 21, r 2 T may be any value in the range of 0 to 1 for the outer diameter of the substrate 21. When the cross section of the flow guiding surface of the flow guiding plate 22 meets the involute equation, the flow guiding surface has a better flow guiding effect, and in the actual production and processing process of the flow guiding plate 22, a person skilled in the art can flexibly select the actual values of the variables in the equation according to the actual requirements, so as to obtain the structure of the flow guiding surface which meets the specific requirements.
Further, in order to reduce the resistance generated by the interaction between the outer side surface of the baffle 22 and the fluid, so as to further improve the flow guiding effect of the whole baffle 22 and improve the stability of the rotor during operation, preferably, the thicknesses of any positions on the baffle 22 can be equal, so that the fluid can move smoothly along the outer side surface of the baffle 22, and correspondingly, the resistance generated by the fluid on the whole baffle 22 during rotation is relatively small; the outer side surface of the baffle 22 is the other surface opposite to the baffle surface of the baffle 22 (the baffle surface is the inner side surface of the baffle) in the thickness direction of the baffle 22. Correspondingly, the cross section of the outer side of the deflector 22 can also be expressed by the following involute equation: x is x 2 ＝(r 1 +h 1 +(r 2 -r 1 -1.5h 1 )*t)*cos(360*t)，y 2 ＝-(r 1 +h 1 +(r 2 -r 1 -1.5h 1 ) T) sin (360 t), which reduces the resistance of the fluid to the outer side of the baffle 22, thereby improving the overall performance of the rotor.
In order to further reduce the difficulty of the coolant flowing from the outside of the inner core 1 to the position of the shaft hole 11, it is preferable that a set distance is provided between the base plate 21 and the outside wall of the inner core 1 in the radial direction of the inner core 1, that is, the outer edge of the base plate 21 in the upper end ring 2 is located closer to the position of the axis of the inner core 1 than the outer edge of the inner core 1, so that a certain gap is formed between the base plate 21 and the outside wall of the inner core 1, and the coolant is easier to enter the range of the guide plate 22 from the outside of the inner core 1 in the radial direction of the inner core 1 and flow to the position of the shaft hole 11 through the end surface of the inner core 1 during the rotation of the rotor, as shown in fig. 3. Specifically, the outer diameter of the base plate 21 may be 1% -3% smaller than the outer diameter of the inner core 1, so that the upper end ring 2 and the inner core 1 can be ensured to have higher connection reliability while the refrigerant has a better flowing effect, and further the overall structure of the rotor is ensured to have higher stability.
For example, as shown in fig. 1, the inner diameter of the inner core 1 may be 21mm, the outer diameter may be 69mm, the inner diameter of the base plate 21 in the upper end ring 2 may be 36mm, the outer diameter may be 67.5mm, and the thickness of the base plate 21 may be 5mm, in which case the cross-sectional shape of the baffle 22 is formed by sandwiching two involute curves extending clockwise with an inner and outer diameter circular arc. Wherein the involute of the cross section of the flow guiding surface (inner side surface) of the flow guiding plate starts from the side wall of the shaft hole 11 of the inner core 1, and the starting point of the involute of the cross section of the outer side surface of the flow guiding plate 22 moves outwards by 2mm along the radial direction of the inner core 1 at the starting point position of the other involute, namely, the thickness of the flow guiding plate 22 is 2mm. Under the above conditions, the equation of the involute corresponding to the flow guiding surface of the flow guiding plate 22 is: x is x 1 ＝(18+13.75*t)*cos(360*t)，y 1 = - (18+13.75×t) sin (360×t); the involute equation corresponding to the outer side of the baffle 22 is x 2 ＝(20+13.75*t)*cos(360*t)，y 2 = - (20+13.75×t) sin (360×t), where t is a value ranging from 0 to 1.
Further, the rotor provided by the invention further comprises an axial flow blade 23, the axial flow blade 23 is fixedly connected to the guide plate 22, so that the flow rate and the circulation effect of the refrigerant in the motor are further improved through the axial flow blade 23 with the guide effect, the shape of the axial flow blade 23 can be similar to the shape design of the blades of a fan and other devices, and therefore, the flow rate and the thoroughly degree of the circulation of the refrigerant in the motor are further promoted in the process that the axial flow blade 23 rotates along with the inner core 1 (or the guide plate 22). Specifically, the axial flow blades 23 can play a role similar to an axial flow fan in the rotation process, and further rotate along with the inner core 1, and the axial flow blades 23 can enhance the exhaust effect in the axial direction of the inner core 1, so that the air suction performance from the lower end of the inner core 1 is further improved, the refrigerant is promoted to be sucked from the other end of the inner core 1, namely, the position of the lower end ring 4 to the position of the upper end ring 2 along the stator-rotor air gap and other channels, the flowing speed and the flowing quantity of the refrigerant from the stator-rotor air gap and other channels are improved, the flowing path of the refrigerant in the compressor motor is optimized, and the refrigerant flows relatively smoothly even along the stator-rotor air gap with relatively smaller size; simultaneously, under the effect of axial flow blade 23, can also promote the exhaust effect of fluid from inner core 1 top, this range and the intensity that can also reduce the axial float when the rotor operates to further promote the operating stability of rotor.
Further, the axial flow blades 23 may be provided in plural, and in order to ensure that the flow guiding effect generated by the axial flow blades 23 is substantially the same, and further ensure the running stability of the rotor, preferably, the axial flow blades 23 may have the same structure, and the inner diameter of each axial flow blade 23 may be not smaller than r 1 An outer diameter of not more than r 2 In view of the spiral structure of the baffle 22, in order to prevent the axial flow blades 23 from protruding from the outer sidewall of the core 1 in the radial direction of the core 1, alternatively, as shown in fig. 1 and 2, part of the axial flow blades 23 may be cross-connected with the baffle 22, that is, the same axial flow blades 23 may be simultaneously distributed on opposite sides of the baffle 22 in the thickness direction thereof, which may also assist the baffle 22 in enhancing the flow guiding effect on the fluid. In addition, in the process of installing the plurality of axial flow blades 23 on the flow guide plate 22, the plurality of axial flow blades 23 can be uniformly distributed along the axial direction around the inner core 1, which can further promote the overall flow guide effect of the plurality of axial flow blades 23 on the fluid, and can prevent the existence of the plurality of axial flow blades 23 from having a great adverse effect on the running stability of the rotor.
Preferably, the angle between any two adjacent axial flow blades 23 may be 1/4-1/2 of the blade angle of the axial flow blades 23, so as to raise the angle and range covered by the axial flow blades 23 as much as possible under the condition of ensuring that the axial flow blades 23 do not interfere with each other when working, so as to further raise the guiding effect of the axial flow blades 23 on the fluid. Specifically, in the case that the inner diameter of the inner core 1 is 21mm and the outer diameter is 69mm, the inner diameter of the blades may be 36mm and the outer diameter may be 67.5mm, that is, the inner diameter and the outer diameter of the axial flow blades 23 may be correspondingly equal to those of the base plate 21, so that the area size of the area covered by the axial flow blades 23 is increased as much as possible under the condition of ensuring the working safety, so as to further improve the comprehensive guiding effect of the plurality of axial flow blades 23 on the fluid. As shown in fig. 4, the axial flow blades 23 have a blade angle α, and any two adjacent axial flow blades 23 are spaced apart by an angle β.
Considering that the path of the fluid with the velocity increased in the flowing process is from the outer side of the inner core 1 to the position of the shaft hole 11 along the radial direction of the inner core 1 under the action of the guide plate 22, in order to prevent adverse effect on the guide effect of the guide plate 22 due to the existence of the axial flow blades 23, preferably, a set distance is formed between the lower ends of the axial flow blades 23 and the base plate 21 along the axial direction of the inner core 1, so that in the working process of the rotor, the fluid can pass through a gap between the guide plate 22 and the base plate 21, and the guide plate 22 can play a normal guide effect. Specifically, the space between the lower end of the axial flow blade 23 and the base plate 21 may be 1/6 to 1/3 of the dimension of the axial flow blade 23 in the axial direction of the core 1.
In addition, when the through holes are formed in the inner core, the inner diameters of the upper end ring 2 and the lower end ring 4 can be larger than the outer diameters of the through holes, so that adverse effects on the through flow effect of the through holes due to the upper end ring 2 and the lower end ring 4 can be avoided.
