Description

Technical Field

[0001] This invention relates to the field of electric system technology, and more specifically to a high-performance electric system. Background Technology

[0002] Electric systems refer to a general term for systems that use electrical energy to achieve specific mechanical or control functions. Their core lies in using electric motors, controllers, and related transmission components to convert electrical energy into mechanical energy or other forms of energy output to meet the needs of different scenarios. With the development of the new energy revolution and power technology, new electric system application scenarios are constantly emerging, which also puts forward new and higher requirements for electric systems.

[0003] From a technical perspective, the core of an electric system is the electric motor. The electric motor converts electrical energy into rotational torque or linear motion through electromagnetic induction. With the development of permanent magnet material technology, permanent magnet synchronous motors (PMSMs), with their outstanding advantages of high operating efficiency, low energy consumption, low noise, and stable power output, are gradually replacing traditional motors and becoming the mainstream model in the field of energy-saving motors. They are widely used in fields with stringent requirements for energy-saving performance and operational stability, such as shipbuilding, high-end industrial manufacturing, and new energy transmission.

[0004] Based on the different mounting structures of permanent magnets, permanent magnet synchronous motors are mainly divided into two categories: surface-mounted and embedded. Surface-mounted permanent magnet synchronous motors have permanent magnets attached to the surface of the rotor core, resulting in a simple structure but weak centrifugal resistance. Embedded permanent magnet synchronous motors embed and fix the permanent magnets inside the rotor core, resulting in higher structural strength and better dynamic performance. To further reduce motor leakage magnetic losses, improve magnetic energy utilization, and optimize energy saving, existing embedded permanent magnet synchronous motors generally eliminate the traditional rotor magnetic isolation bridge structure. However, without the magnetic isolation bridge, the rotor core cannot effectively limit and fix the embedded permanent magnets. To prevent the permanent magnets from loosening under centrifugal force during high-speed motor operation, current technologies generally use methods such as winding carbon fiber wires on the surface of the rotor core or using an interference fit with carbon fiber sleeves to press and fix the permanent magnets. However, the carbon fiber winding process is complicated and highly dependent on manual labor. The overall assembly is time-consuming and labor-intensive, resulting in extremely low production and assembly efficiency, which is not conducive to the large-scale mass production of energy-saving motors. Using carbon fiber sleeves, on the other hand, presents challenges in installation and is prone to problems such as improper assembly and failure of permanent magnet clamping. Summary of the Invention

[0005] This invention provides a high-performance electric system that reconfigures the motor design to make the motor and electric drive chain run more stably and quietly. It also features insulated transmission components that are compatible with the motor, achieving high insulation, high strength, and meeting the requirements of high-voltage transmission, thus adapting to higher power requirements and solving the manufacturing and usage problems in existing electric systems.

[0006] The present invention provides a high-performance electric system with the following technical solution: A high-performance electric system includes an electric motor, which includes a housing, a stator, and a rotor. The stator is installed inside the housing, and the rotor is installed inside the stator. The rotor includes a main shaft, a rotor core, and a sleeve. The rotor core is rotatably installed inside the stator and coaxial with the stator. The main shaft is coaxial with and fixedly connected to the rotor core. Multiple mounting slots are evenly distributed along the circumferential direction of the rotor core. Each mounting slot contains two permanent magnets, which are arranged sequentially around the circumferential direction of the rotor core and are in contact with it. Two pressure blocks are provided between the two permanent magnets in the same mounting slot. The pressure blocks are arranged sequentially around the circumference of the rotor core. Each pressure block is in contact with the permanent magnet adjacent to it. An elastic element is provided between the two pressure blocks, which always tends to push the two pressure blocks away from each other. The outer diameter of the rotor core is smaller than the inner diameter of the sleeve, and the sleeve is fitted over the pressure blocks and the rotor core. The two pressure blocks in the same mounting slot have a first state and a second state. In the first state, the two pressure blocks move inward and approach each other. In the second state, the two pressure blocks move outward and move away from each other. The side that is closer to the central axis along the radial direction of the rotor core is called the inner side, and the side that is farther from the central axis is called the outer side.

[0007] Furthermore, the sleeve is made of composite material.

[0008] Furthermore, multiple protrusions are evenly distributed on the inner circumferential wall of the sleeve, and each of the protrusions can contact the outer circumferential wall of the rotor core.

[0009] Furthermore, the two pressure blocks located in the same mounting groove are referred to as the first block and the second block, respectively. The first block is provided with a first spring piece, and the second block is provided with a second spring piece. The first spring piece has a V-shaped structure, and the structure of the second spring piece is the same as that of the first spring piece. One side of the first spring piece is fixed to the first block, and the other side is pressed between the second block and the permanent magnet arranged adjacent to the second block. One side of the second spring piece is fixed to the second block, and the other side is pressed between the first block and the permanent magnet arranged adjacent to the first block.

[0010] Furthermore, the first spring includes a main body and two pressure plates. The main body is fixedly connected to the first piece, and the two pressure plates are arranged sequentially on the main body along the axis of the spindle and are both fixedly connected to the main body.

[0011] Furthermore, the pressure plate includes multiple spring claws, which are sequentially arranged on the main body along the spindle axis and are all fixedly connected to the main body. The multiple spring claws of the first spring piece and the multiple spring claws of the second spring piece are arranged alternately.

[0012] Furthermore, a high-performance electric system also includes a bracket and a transmission mechanism, with the housing mounted on the bracket; the transmission mechanism includes a first transmission shaft, an insulated transmission shaft, a second transmission shaft, a third transmission shaft, and an output shaft; the first transmission shaft is rotatably mounted on the bracket, and one end of the first transmission shaft is connected to the main shaft via a coupling; the insulated transmission shaft, the second transmission shaft, the third transmission shaft, and the output shaft are connected in sequence via universal joints, and the other end of the insulated transmission shaft is connected to the first transmission shaft, and the other end of the output shaft is equipped with the component to be driven.

[0013] Furthermore, a mounting cylinder is fixedly installed on the bracket, and a rotating cylinder is coaxially rotatably installed inside the mounting cylinder. The rotating cylinder has an L-shaped structure and can rotate around its own axis. The second drive shaft is coaxially installed with the rotating cylinder and rotates in cooperation with it. The third drive shaft and the output shaft are both installed inside the rotating cylinder.

[0014] Furthermore, a first motor is fixedly mounted on the bracket, a worm gear is mounted on the shaft of the first motor, and a turbine gear is coaxially and fixedly mounted on the rotating cylinder, with the turbine gear meshing with the worm gear.

[0015] Furthermore, the insulated drive shaft includes an insulated tube, which is made by winding insulating fibers with epoxy resin, curing agent and accelerator.

[0016] The beneficial effects of this invention are as follows: The high-performance electric system of this invention, by setting an elastic element in cooperation with two pressure blocks, allows the pressure blocks to be retracted during assembly, reducing the outer diameter of the rotor core assembly and eliminating interference during sleeve assembly. This allows the sleeve to be directly fitted into place. After the sleeve is in place, the pressure blocks are reset under the restoring force of the elastic element, completing the interference fit between the sleeve and the pressure blocks. Assembly is simple and convenient, reducing the difficulty of the assembly process. Furthermore, relying on the elastic pushing action of the elastic element, the pressure blocks form a continuous, uniform, and controllable pre-tightening pressure on the permanent magnet. The clamping amount can be adaptively adjusted according to the structural dimensions, improving the uniformity of force on the permanent magnet and avoiding problems such as excessive local compressive stress or insufficient clamping. Moreover, during motor startup, the elastic element has good flexible buffering capacity, effectively absorbing vibration and impact stress, mitigating impact damage to the permanent magnet, and protecting it. This results in high production efficiency, light weight, high dynamic balance performance, stable and quiet operation, and high electrical insulation strength of the transmission chain. It can be widely used in fields with stringent requirements for energy-saving performance and operational stability, such as shipbuilding, high-end industrial manufacturing, and new energy transmission.

[0017] Furthermore, by setting the first and second spring plates, during the rotation of the rotor core, the pressure blocks, under the action of centrifugal force, will move further closer to the inner wall of the sleeve. At this time, the two pressure blocks will rotate relative to the sleeve under the urging of the arc surface of the inner wall of the sleeve. The first and second spring plates then further press the adjacent permanent magnets together. The cooperation of the first and second spring plates prevents the permanent magnets from shifting outwards due to the centrifugal force of the pressure blocks, thus preventing loose fixing. The greater the centrifugal force, the tighter the pressure, further improving the stability of the clamping.

[0018] Furthermore, by setting an insulated drive shaft, the goal of achieving high insulation, high strength, and meeting the requirements of high-voltage transmission can be achieved. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] An embodiment of the high-performance electric system of the present invention, such as Figures 1 to 11 As shown.

[0024] A high-performance electric system includes a motor 100, which comprises a housing 110, a stator 120, and a rotor 130. The stator 120 is installed within the housing 110, and the rotor 130 is installed within the stator 120. One end of the housing 110 is sealed by an end cap 111. The rotor 130 includes a main shaft 131, a rotor core 132, and a sleeve 133. The rotor core 132 is rotatably mounted within the stator 120 and coaxial with it. Both ends of the rotor core 132 are provided with pressure caps. The main shaft 131 is coaxial with and fixedly connected to the rotor core 132. Multiple mounting slots are evenly distributed in the circumferential direction of the rotor core 132; specifically, six mounting slots are provided. The cross-section of each mounting slot perpendicular to the axis of the rotor core 132 is fan-shaped. Each mounting slot is equipped with two permanent magnets 134, which are arranged sequentially around the circumferential direction of the rotor core 132 and are in contact with the rotor core 132.

[0025] Two pressure blocks 135 are provided between the two permanent magnets 134 in the same mounting slot. The two pressure blocks 135 are arranged sequentially around the circumferential direction of the rotor core 132. Both pressure blocks 135 are in contact with the permanent magnets 134 arranged next to them. Specifically, each pressure block 135 is provided with a receiving groove, which can wrap and limit the permanent magnets 134 arranged next to it.

[0026] An elastic element 136 is provided between the two pressure blocks 135. The elastic element 136 always tends to push the two pressure blocks 135 away from each other; the elastic element 136 is an elastic ring. The sleeve 133 is made of composite material, specifically one or more of carbon fiber, glass fiber, Kevlar fiber, rock fiber, and metal fiber.

[0027] The outer diameter of the rotor core 132 is smaller than the inner diameter of the sleeve 133, and the sleeve 133 is fitted over the pressure block 135 and the rotor core 132. The two pressure blocks 135 in the same mounting slot have a first state and a second state. In the first state, the two pressure blocks 135 move inward and approach each other; in the second state, the two pressure blocks 135 move outward and move away from each other. The side closer to the central axis along the radial direction of the rotor core 132 is called the inner side, and the side farther away from the central axis is called the outer side.

[0028] When assembling the rotor 130, the operator can use an external clamp or operate manually to press the two pressure blocks 135 inward within the mounting slot. Taking two pressure blocks 135 in the same mounting slot as an example, the two pressure blocks 135 will overcome the elastic force of the elastic element 136, move inward along the corresponding permanent magnet 134 and approach each other, reducing the outer diameter of the rotor core 132 and eliminating assembly interference. At this time, the pressure blocks 135 are in the first state, and the sleeve 133 can be directly fitted onto the outside of the rotor core 132 and the pressure blocks 135, reducing the assembly difficulty of the sleeve 133. After the sleeve 133 is in place, the external pressure force on the two pressure blocks 135 is removed, and the pressure blocks 135 automatically switch to the second state under the reset elastic force of the elastic element 136. The two pressure blocks 135 move away from each other and push outward, cooperating with the inner wall of the sleeve 133 for limiting, completing the interference fit between the sleeve 133 and the pressure blocks 135.

[0029] By setting the elastic element 136 to cooperate with the two pressure blocks 135, the pressure blocks 135 can be retracted during assembly, reducing the assembly outer diameter of the rotor core 132 and eliminating assembly interference of the sleeve 133. This allows the sleeve 133 to be directly fitted into place. After the sleeve 133 is in place, the pressure blocks 135 complete the interference fit between the sleeve 133 and the pressure blocks 135 under the restoring elastic force of the elastic element 136. The assembly is simple and convenient, reducing the difficulty of the assembly process. Furthermore, relying on the elastic pushing action of the elastic element 136, the pressure blocks 135 form a continuous, uniform, and controllable pre-tightening pressure on the permanent magnet 134. The clamping amount can be adaptively adjusted according to the structural dimensions, improving the uniformity of the force on the permanent magnet 134 and avoiding the problem of excessive local compressive stress or insufficient clamping. Moreover, when the motor 100 is running, the elastic element 136 has good flexible buffering ability, which can effectively absorb vibration and impact stress, alleviate impact damage to the permanent magnet 134, and protect the permanent magnet 134.

[0030] Furthermore, a high-performance electric system also includes a bracket 200, on which the housing 110 is fixedly mounted.

[0031] In a further embodiment, a plurality of protrusions 137 are evenly distributed on the inner peripheral wall surface of the sleeve 133. The protrusions 137 are also made of composite materials, specifically one or more of carbon fiber, glass fiber, Kevlar fiber, rock fiber, and metal fiber. All of the protrusions 137 can contact the outer peripheral wall surface of the rotor core 132, or the plurality of protrusions 137 can transitionally fit with the outer peripheral wall surface of the rotor core 132.

[0032] In this embodiment, by setting the protrusion 137, there is no interference fit between the protrusion 137 and the rotor core 132 during the sleeve 133 fitting process. Furthermore, the retraction of the pressure block 135 reduces the outer diameter of the rotor core 132, without affecting normal fitting. The protrusion 137 also improves the overall tensile strength of the sleeve 133. After the sleeve 133 is fitted, when the motor 100 suddenly accelerates or stops, the protrusion 137 can withstand the load on the permanent magnet 134, further protecting the permanent magnet 134 and preventing damage. It should be noted that the protrusion 137 and the two pressure blocks 135 in the same mounting groove are spaced apart, and the area occupied by the protrusion 137 is small, so it does not affect assembly or the pressure of the pressure block 135 on the permanent magnet 134.

[0033] In a further embodiment, the two pressure blocks 135 located in the same mounting groove are referred to as the first block 138 and the second block 139, respectively. The first block 138 is provided with a first spring piece 140, and the second block 139 is provided with a second spring piece 150. The first spring piece 140 has a V-shaped structure, and the structure of the second spring piece 150 is the same as that of the first spring piece 140. One side of the first spring piece 140 is fixedly connected to the first block 138, and the other side is pressed between the second block 139 and the permanent magnet 134 adjacent to the second block 139; one side of the second spring piece 150 is fixedly connected to the second block 139, and the other side is pressed between the first block 138 and the permanent magnet 134 adjacent to the first block 138.

[0034] The first spring 140 includes a main body 141 and two pressure plates 142. The main body 141 is fixedly connected to the first block 138. The two pressure plates 142 are arranged sequentially on the main body 141 along the axis of the main shaft 131 and are both fixedly connected to the main body 141. The main body 141 and the two pressure plates 142 form a V-shaped structure.

[0035] Furthermore, the pressure plate 142 includes multiple spring claws, which are sequentially arranged on the main body 141 along the axis of the main shaft 131 and are all fixedly connected to the main body 141. The multiple spring claws of the first spring piece 140 and the multiple spring claws of the second spring piece 150 are arranged alternately.

[0036] In this embodiment, by setting a first spring plate 140 and a second spring plate 150, during the rotation of the rotor core 132, the pressure block 135, under the action of centrifugal force, will further move closer to the inner wall of the sleeve 133. At this time, the two pressure blocks 135 will rotate relative to the sleeve 133 under the urging of the arc surface of the inner wall of the sleeve 133. See Figure 11 As shown in the figure, the first block 138 will rotate clockwise (slightly wobbling) relative to the sleeve 133, and the second block 139 will rotate counterclockwise (slightly wobbling) relative to the sleeve 133. The rotation of the first block 138 will drive the first spring piece 140 fixed to it to rotate clockwise, thereby further pressing the adjacent permanent magnet 134 through the first spring piece 140. The rotation of the second block 139 will drive the second spring piece 150 fixed to it to rotate counterclockwise, thereby pressing the adjacent permanent magnet 134 through the second spring piece 150. By using the cooperation of the first spring piece 140 and the second spring piece 150, the permanent magnet 134 is prevented from being loosely fixed due to the centrifugal force of the pressure block 135. The greater the centrifugal force, the tighter it is pressed, further improving the stability of clamping.

[0037] Alternatively, in a further embodiment, a high-performance electric system may also include a transmission mechanism 300, which includes a first transmission shaft 310, an insulated transmission shaft 320, a second transmission shaft 330, a third transmission shaft 340, and an output shaft 350.

[0038] The first drive shaft 310 is rotatably mounted on the bracket 200 via a bearing housing, and one end of the first drive shaft 310 is connected to the main shaft 131 via a coupling. One end of the insulated drive shaft 320 is connected to the other end of the first drive shaft 310 via a first universal joint, one end of the second drive shaft 330 is connected to the other end of the insulated drive shaft 320 via a second universal joint, one end of the third drive shaft 340 is connected to the other end of the second universal joint via a third universal joint, one end of the output shaft 350 is connected to the other end of the third drive shaft 340 via a fourth universal joint, and the component to be driven is mounted on the other end of the output shaft 350.

[0039] When the high-performance electric system of this embodiment is applied in a ship, the impeller can be mounted on the other end of the output shaft 350. This allows the motor 100 to drive the impeller to rotate via the first drive shaft 310, the insulated drive shaft 320, the second drive shaft 330, the third drive shaft 340, and the output shaft 350 after starting, thus providing the ship with forward or reverse power. Of course, the high-performance electric system of this embodiment can also be installed on other driven equipment.

[0040] Furthermore, a mounting cylinder 360 is fixedly installed on the bracket 200, and a rotating cylinder 370 is coaxially and rotatably installed inside the mounting cylinder 360. The rotating cylinder 370 has an L-shaped structure and can rotate around its own axis. The second transmission shaft 330 is coaxially installed with the rotating cylinder 370 and rotates in cooperation with it. The third transmission shaft 340 and the output shaft 350 are both installed inside the rotating cylinder 370.

[0041] Specifically, a first motor is fixedly mounted on the support 200, and a worm gear 390 is mounted on the shaft of the first motor. A turbine 380 is coaxially mounted and fixedly mounted on the rotating cylinder 370, and the turbine 380 meshes with the worm gear 390. The rotating cylinder 370 includes a straight section and a curved section, which are fixedly connected.

[0042] By setting up the rotating cylinder 370, when in use, the first motor is started. The starting of the first motor drives the worm gear 390 to rotate the turbine 380. The rotation of the turbine 380 will drive the rotating cylinder 370 to rotate, thereby realizing the steering operation.

[0043] Furthermore, the insulated drive shaft 320 includes an insulating tube made of high-strength insulating material. Specifically, it can be made by winding high-strength insulating fiber filaments with epoxy resin, curing agent and accelerator to form a new type of insulated shaft tube to replace the traditional steel pipe, thereby achieving high insulation, high strength and meeting the purpose of high voltage transmission.

[0044] Alternatively, in another possible embodiment, in order to achieve transmission at different distances, the insulated transmission shaft 320 further includes a telescopic rod, which is disposed between the first universal joint and the insulating tube. The telescopic rod includes a sleeve and a telescopic tube. The sleeve is installed on the first universal joint, and the telescopic tube is installed on the insulating tube. The telescopic rod and the sleeve are keyed together, so that the telescopic rod and the sleeve 133 can rotate synchronously and slide relative to each other axially.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
