With the development of motor technology, permanent magnet motors are continuously developing towards high power, and the pace of replacing low-power machines with new high-power main machines is increasing more and more rapidly. Particularly, in recent years, offshore wind power rises, and the trend of single-machine capacity enlargement is more obvious.
The increase of the motor power inevitably leads to the increase of the volume and the weight of the motor, and the transportation problem brought along with the increase of the motor power is also highlighted. At present, the width of the motor is limited by land transportation, and the outer diameter of the motor is generally required to be not more than 5 m. Therefore, when the outer diameter of the motor exceeds 5m, the transportation of the motor is limited. Meanwhile, the increase of the outer diameter of the motor can increase the transportation difficulty in the transportation process, so that the transportation cost is increased.
In the prior art, in order to avoid the transportation problem caused by the overlarge outer diameter of the motor, the outer diameter of the high-power motor is forced to be selected and controlled, and the requirement of the motor on power is met by utilizing a method of lengthening the axial length. However, the increase of the axial length of the motor can reduce the utilization rate of motor materials, thereby increasing the production cost and reducing the product competitiveness.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The core of the invention is to provide a rotor structure which avoids the limitation of land transportation width to the outer diameter of the motor and does not increase the production cost. Another core of the present invention is to provide a permanent magnet motor including the above rotor structure.
Referring to fig. 1-6, fig. 1 is a partial schematic view of a permanent magnet motor according to an embodiment of the present invention; FIG. 2 is a schematic structural diagram of the rotor module of FIG. 1; FIG. 3 is a schematic three-dimensional view of the rotor assembly of FIG. 1; FIG. 4 is a cross-sectional schematic view of the rotor module shown in FIG. 2; FIG. 5 is a schematic cross-sectional view of a variation of the rotor module shown in FIG. 2; fig. 6 is a schematic cross-sectional view of another variation of the rotor module shown in fig. 2.
The invention provides a modular rotor structure, which comprises at least two rotor modules 11 segmented along the circumferential direction, wherein each rotor module 11 comprises a module magnetic pole 112, a module magnetic yoke 111, a module rib plate 113 and a module fixing plate 114; and, the module magnetic pole 112 is installed on the module magnetic yoke 111, the module rib plate 113 and the module fixing plate 114 are both fixedly connected with the module magnetic yoke 111, the module rib plate 113 is used for detachably connecting the adjacent rotor modules 11, and the module fixing plate 114 is detachably connected with the module connecting flange 12.
The motor can be dismantled modular rotor structure at the in-process of transportation, is about to be connected between rotor module 11 and module flange 12, is connected between each adjacent rotor module 11 and dismantles, and the external diameter of motor just becomes stator structure's external diameter size like this, and the external diameter size that only needs stator structure satisfies the restriction to motor external diameter size in the road traffic transportation. Because the stator structure is positioned in the rotor structure, and the air gap 3 is arranged between the stator structure and the rotor structure, when the outer diameter of the stator structure of the motor meets the requirement on the outer diameter of the motor in the land transportation process, the outer diameter of the rotor structure can be larger than the limit size of the outer diameter of the motor in the land transportation process.
In the transportation process, in order to facilitate transportation of the module magnetic poles 112, the module magnetic poles 112 can be transported separately, and after transportation is completed, the module magnetic poles 112 are installed on the module magnetic yokes 111; it is of course also possible to first mount it on the module yoke 111 and then transport the rotor module 11 with the module poles 112 mounted thereon.
The adjacent rotor modules 11 are detachably connected through module rib plates 113, and the module rib plate fasteners 15 can be bolts or other connection modes meeting requirements; the module fixing plate 114 is detachably connected to the module connecting flange 12, and the module fixing plate fastening members 14 may be bolts or other connection methods meeting the requirements.
The rotor modules 11 in the modular rotor structure are distributed in a segmented manner along the circumferential direction, and all the rotor modules 11 are combined together along the circumferential direction to form the rotor assembly 1.
This modular rotor structure makes high-power motor can realize dismantling of rotor assembly 1 in the in-process of transportation, then stator assembly 2 transports respectively with rotor assembly 1, makes the external diameter size of high-power motor become the external diameter size of stator assembly 2 in the transportation, and when the external diameter size of stator assembly 2 satisfied the restriction to the motor external diameter in the road transportation, the external diameter of rotor assembly 1 can be greater than the restriction to the motor external diameter size in the road transportation. Therefore, under the same road traffic rules, the outer diameter of the high-power motor can be further increased, so that the power of the motor can be increased, and the requirements on the motor power and the road traffic rules in actual production can be met.
In addition, from the perspective of processing and manufacturing, the integral rotor assembly has high processing difficulty in the processing process, is easy to deform in the processing, hoisting and transporting processes, and has high scrap loss cost, thereby increasing the production and manufacturing cost. In the process of processing and manufacturing the modular rotor structure, the size of parts is reduced, the processing difficulty is reduced, and the parts are not easy to deform in the using process, so that the scrapping loss cost is reduced, the production and manufacturing cost is further reduced, and the market competitiveness of products is improved.
Therefore, the modular rotor structure can enable the high-power motor to avoid the limitation of the road traffic transportation rule, and meanwhile, the production cost can be reduced, and the product competitiveness is improved.
On the basis of the above specific embodiment, considering that the number of poles of some high-power motors is large, if only one magnetic pole mounting plane is located in one module yoke 111, the number of module yokes 111 needs to be increased, the number of module rib plates 113 and module fixing pieces 114 is increased correspondingly, the number of connecting parts needing to be disassembled and assembled in the disassembling and assembling process is increased, and the operation process is also complicated, so that at least one module magnetic pole mounting plane is arranged in one module yoke 111, and angles between all adjacent module magnetic pole mounting planes are the same, as shown in fig. 5.
Specifically, the cross-section of the module pole mounting plane in the module yoke 111 has a polygonal structure, and when all the rotor modules 11 are assembled together, the cross-section of all the module pole mounting planes exactly form a regular polygon having the same inscribed circle, and the distances of all the module pole mounting planes from the center of the rotor assembly are equal. Of course, for installation or machining reasons, this regular polygon is only an approximate shape and does not meet the strict dimensional criteria of the geometric definition. The module poles 112 are mounted on the module pole mounting surface of the module yoke 111, and all the module poles 112 are uniformly distributed in the circumferential direction.
The number of rotor modules 11 can be reduced by increasing the number of module pole mounting planes in the module yoke 111, so that the number of connections between adjacent rotor modules 11 and the number of connections between the rotor modules 11 and the module connecting flange 12 can be correspondingly reduced. The process of assembling or disassembling the rotor module 11 is simpler, and the time for disassembling and assembling is saved.
Of course, all of the module yokes 111 do not have the same number of module pole mounting planes, and the number of module pole mounting planes of the module yokes 111 may be different in the same motor.
Of course, here, the module pole mounting surface is provided as a flat surface, and the module pole mounting surface of the module yoke 111 is provided as a flat surface so as to match the shape of the mounting surface of the module pole 112, considering that the module pole 112 has a flat mounting surface. In addition to the above-described embodiment, in consideration of the case where the mounting surfaces of the module poles 112 have arc surfaces, the module pole mounting surfaces of the module yokes 111 have arc surfaces having the same radius.
Specifically, the cross-sections of the module pole mounting surfaces in the module yoke 111 are circular arcs having the same radius, and when all the rotor modules 11 are assembled together, the cross-sections of all the module pole mounting surfaces exactly form a circle, and the distances of all the module pole mounting surfaces from the center of the rotor assembly are equal. Of course, for mounting or machining reasons, this circular shape is only a rough shape and does not meet the strict dimensional criteria of the geometric definition. The module poles 112 are mounted on the module pole mounting surface of the module yoke 111, and all the module poles 112 are uniformly distributed in the circumferential direction.
The shape of module magnetic pole installation face in module yoke 111 is the arc surface, can cooperate the installation face to be the installation of the module magnetic pole 112 of arc surface, simultaneously, in the in-process of processing, compare in processing multilateral structure, need not divide in the course of working of arc surface, operations such as angle measurement, make the process of processing simpler, easy to operate, more save process time to reduce the cost of manufacturing, further improve the market competition of product.
The module magnetic pole mounting surface can be an arc surface with a uniform angle, that is, each module magnetic yoke 111 has a module magnetic pole mounting surface with the same size, the module magnetic poles 112 can adopt the same positioning structure in the mounting process, and the positioning process is simpler; of course, the module magnetic yoke 111 may also be an arc surface with a non-uniform angle, and each module magnetic yoke has a module magnetic pole mounting surface with a different size.
On the basis of the above embodiment, considering that the uniformity of the air gap 3 between the rotor assembly 1 and the stator assembly 2 has a large influence on the overall performance of the motor, and the higher the uniformity of the air gap 3 is, the better the performance of the motor is, the connection between the rotor module 11 and the stator assembly 2 can be configured to be adjustable, as shown in fig. 2.
Specifically, the module fixing plate 114 may be provided with a first through hole, which is larger than a size required for connecting with the module connecting flange 12, so that the relative position between the rotor module 11 and the module connecting flange 12 may be adjusted through the first through hole according to actual conditions, that is, the relative position between the rotor module 11 and the stator assembly 2 may be adjusted, so as to adjust the air gap 3. And then the relative positions of all the rotor modules 11 and the module connecting flanges 12 are adjusted one by one, so that the consistency of the air gap 3 can be adjusted.
Because the air gap 3 in the invention can be realized by adjusting the relative positions of the plurality of rotor modules 11 and the module connecting flange 12, compared with the prior integrated rotor structure, the consistency of the air gap 3 can be adjusted only by adjusting the position of the whole rotor, the consistency of the adjusted air gap 3 in the embodiment of the invention is higher, and the performance of the motor is correspondingly improved.
Of course, the first through hole may have any shape as long as the relative position between the rotor module 11 and the module connecting flange 12 can be adjusted, and the first through hole may be used to fix the connecting position between the rotor module 11 and the module connecting flange 12.
On the basis of the above specific embodiment, considering that the adjustment process of the consistency of the air gap 3 is relatively complex, a plurality of pin holes can be processed on the module fixing plate 114, and after the relative position of the rotor module 11 and the module connecting flange 12 is adjusted, the positioning is performed in a manner of drilling the pin holes, so that the air gap 3 does not need to be adjusted again in the next installation process.
Specifically, the module fixing plate 114 is provided with a plurality of pin holes, and after the consistent adjustment of the air gap 3 between the rotor module 11 and the stator assembly 2 is completed, the pin holes on the module fixing plate 114 and the module connecting flange 12 are used for pin hole drilling, and the parts connected with each other are marked, so that after the module is disassembled again, the positioning and recovery assembly process only needs to install the positioning pins 13 on the corresponding pin holes in the module, the consistency of the air gap 3 does not need to be adjusted again, the complex operation of repeatedly adjusting the air gap 3 is avoided, and the working time is saved.
It should be further noted that the pin hole matching drilling herein means that the module fixing plate 114 has a pin hole, but the module connecting flange 12 does not have a pin hole, and after the consistency adjustment of the air gap 3 is completed, a pin hole matching with the pin hole on the module fixing plate 114 is machined at a position corresponding to the pin hole on the module connecting flange 12 and corresponding to the pin hole on the module fixing plate 114.
On the basis of the above embodiment, in consideration of the fact that the adjacent rotor modules 11 need to be connected through the module rib plate 113, the module rib plate 113 is provided with a second through hole for adjusting the connection position.
In the process of adjusting the air gap 3, not only the relative position between the module fixing plate 114 and the module connecting flange 12, but also the relative position between the adjacent rotor modules 11 may need to be adjusted, so that the second through holes for adjusting the connecting positions of the adjacent rotor modules 11 are processed on the module rib plates 113, and the fastening position can be adjusted at any time according to the adjustment of the air gap 3. Meanwhile, the second through hole can also be used for fixing the adjacent rotor modules 11, so that the adjacent rotor modules 11 are connected more firmly, and the condition of looseness in the high-speed rotation in the working process is avoided.
The fastening means here may be a bolt fastening, and in order to avoid loosening, it may be glued firmly with a suitable glue. Other fastening and anti-loosening modes can be adopted, and are not described in detail herein.
In addition, the second through hole may have any shape, as long as the second through hole can adjust the relative position between the adjacent rotor modules 11, and can be used to fix the adjacent rotor modules 11.
It should be further noted that the first through hole mentioned in the present invention is a through hole on the module fixing plate 114 for adjusting the relative position between the module fixing plate 114 and the module connecting flange 12, and the second through hole is a through hole on the module rib 113 for adjusting the relative position between the adjacent rotor modules 11, and is only for distinguishing the through holes in different positions, and is not sequentially arranged.
On the basis of the above-described embodiment, the modular magnetic pole 112 is designed to be an axial segmented structure in consideration of the difficulty in machining and installation of the modular magnetic pole 112.
The module magnetic pole 112 with the axial segmented structure is shorter in the length direction than before, the magnetic force is smaller than before during installation, and the influence of the magnetic force is smaller during the installation process, so the difficulty of the installation process is reduced; in addition, after the size is shortened, the module magnetic pole 112 is simpler in the process of machining and manufacturing, and the difficulty of machining and manufacturing is reduced.
Besides the above-mentioned modular rotor structure, the present invention also provides a permanent magnet motor including the modular rotor structure disclosed in the above-mentioned embodiments, and the structures of other parts of the permanent magnet motor refer to the prior art, which is not described herein again.
