Description

Intelligent motor design method, motor and deviation correction method thereof Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to an intelligent motor design method, a motor and a deviation correction method thereof. Background Art

[0002] Motors include electric motors and generators. They are devices that realize the mutual conversion between electrical energy and mechanical energy. They have been widely used in various industries. When the motor moves at high speed, its mechanical part may rotate or tilt, causing the motor to not be in the normal working point. If there is no correction method, the motor's working performance will be reduced. In severe cases, it will cause abnormal noise in the motor or even damage the motor. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the existing technology and propose a new high-performance intelligent motor design method, motor and its correction method. By designing an adaptive tension spring structure in the rotor assembly, the interference of the motor position or other external forces on the motor movement is avoided. The rotor automatically seeks balance according to the centripetal force during high-speed rotation, ensuring the high-speed operation performance of the motor and reducing losses, ensuring that the motor can run at an ultra-high speed state for a long time. At the same time, an aerodynamic design suitable for the ultra-high-speed operation state of the motor is designed at the casing, so that the motor air is in a diversion operation state.

[0004] The object of the present invention is achieved through the following technical solution: a method for designing an intelligent motor, wherein the motor includes a stator assembly, a rotor assembly, a housing, and a control board, and the method includes:

[0005] The stator assembly is designed by winding N sets of stator core components in series without spacing to form a closed structure. Each set of stator core components includes a stator module, a winding slot sleeved on the stator module, an external coil wound on the winding slot, a wiring bracket, and a PIN mounted on the wiring bracket, forming a continuous stator slot with no spacing in the closed structure.

[0006] A rotor assembly is designed with springs positioned at both ends of the magnetic core. The springs support the bidirectional movement of the magnetic core, forming an adaptive tension spring structure. This adaptive tension spring structure allows the rotor assembly to automatically find balance based on centripetal force during ultra-high-speed rotation. The adaptive tension spring structure includes a motor shaft, a magnetic core, and a spring. The magnetic core is mounted on the motor shaft. The springs are mounted on the motor shaft and located at both ends of the magnetic core, supporting the movement of the magnetic core from front to back.

[0007] The casing is designed, and arc-shaped guide vanes, guide grooves and high-speed fan guide vanes cooperating with the motor are integrally formed in the casing, forming a rotating air duct structure suitable for the ultra-high-speed operation of the motor. The air entering the motor is discharged through the rotating air duct structure, so that the discharged air forms a rotating airflow, the air outlet speed is higher, and the air outlet position can be customized; and symmetrical hollow positions are formed at the end of the casing, so that the motor rotating air duct takes away heat through the hollow positions, thereby improving the working power and speed of the motor. At the same time, bearings are provided in the casing, so that the whole structure is an adaptive magnetic field balancing body with bearings; the rotating air duct structure is integrally formed in the casing, so that the rotating air duct structure as a whole is firmly fixed, wherein smooth arc-shaped guide vanes are used, and the direction of the arc-shaped guide vanes is consistent with the direction of the air entering the motor, so that the whole is in a diversion operation state, thereby allowing wind power to smoothly enter and exit the motor, reducing internal losses, and being suitable for high-speed rotation of the motor;

[0008] A control board is designed to drive the motor and integrate an active voice noise reduction calculation model. It can automatically switch between different noise reduction modes according to the environment to achieve noise reduction output.

[0009] Furthermore, the symmetrical hollowed-out positions at the end of the housing are connected to the tail plate of the motor through PIN pins to supply power.

[0010] Furthermore, the active speech noise reduction calculation model adjusts ANC controller parameters according to the wind noise detection result, optimizes wind noise leakage, and achieves a rapid and sharp reduction of the erroneous signal input to the filter, thereby reducing noise.

[0011] Furthermore, the stator core component includes a stator module, a winding slot sleeved on the stator module, an external coil wound on the winding slot, a wiring bracket, and a PIN pin installed on the wiring bracket, which serves as the minimum working module of the stator. The stator core component is a multi-in-one spacing-free design. The components of each stator core component are designed and modeled using the copy and paste mode of software modeling design to ensure low errors of each component. The stator core component array is stamped and formed into a stator core component array in one go using a high-precision mold to ensure high similarity between each stator core component. The outer side of the stator module in each group of stator core components is micro-engraved with multiple convex floating lines. The total length of the lines of N groups of stator core components after being arranged in line is measured, and the similarity between the N groups of stator core components is obtained by calculating the ratio between the total lengths of the lines of the N groups of stator core components. When the similarity is not less than a preset percentage, the N groups of stator core components are used for assembly. Conversely, when the similarity is less than the preset percentage, the N groups of stator core components are not used for assembly to ensure the consistency of each stator core component.

[0012] Further, the wiring bracket is attached to the starting and ending wire ends of the enameled wire of the externally wound coil, and is used to fix the position of the connecting wire of the externally wound coil; the wiring bracket is designed with a stepped structure, and the diameters at both ends of the wiring bracket are larger than the diameter of the middle part of the wiring bracket, which is convenient for fixing the connecting wire of the externally wound coil, so that the connecting wire will not move along with the winding needle during the winding process, and at the same time prevent the connecting wire from being displaced due to the up and down vibration of the motor during high-speed operation; the externally wound coil is a coil fixed by the external winding method, and the tension of the enameled wire of the coil is kept constant during the winding process.

[0013] Further, a through non-spacing stator slot is formed in the closed structure, which is used to improve the quality and slot fill factor of the externally wound coil; the closed structure includes a cylindrical structure, and the closed structure forms an inner ring wall and an outer ring wall, and then wraps the externally wound coil inside the closed structure, isolating the externally wound coil from contacting other motor components. When the motor runs at high speed, the structural vibration of each part of the motor will not cause the externally wound coil to collide and be damaged, and at the same time avoid short circuits; the non-spacing stator slot has a structure similar to the shape of the Chinese character "工", and the long ends of each non-spacing stator slot are connected in a non-spacing manner to form the outer ring wall, and the short ends of each non-spacing stator slot are connected in a circular manner to form the inner ring wall. The long ends and short ends of the non-spacing stator slot both protrude radially outwards to form an inner space with a large radial space, which is convenient for the wiring of the externally wound coil, so that the slot fill factor reaches the design limit, and is used to support the motor to work at high speed and ultra-high speed for a long time.

[0014] Further, the M groups of stator core components form a single-phase stator, where M < N. Multiple groups of single-phase stators are combined into a multi-phase stator through a high-precision symmetric design, ensuring a high similarity between the electrical characteristics of each single-phase stator, and at the same time keeping the error between the phase resistances of each single-phase stator not greater than 0.1 ohm and the phase inductance error not greater than 0.1 microhenry, so that the motor can work in an ultra-high speed state or an ultra-quiet state.

[0015] Further, after the N groups of stator core components are arranged in a straight line, they are wound and assembled into a closed structure by using a one-time bending and forming process. If the number of bending times exceeds once, the connection between each stator core component will automatically break; among them, the one-time bending and forming process includes: a thin connecting piece with multiple hidden micro-reinforcing ribs is designed at the connection of the stator core components, so that the combined structure has the characteristics of one-time forming, and at the same time ensures that the closed structure does not deform.

[0016] A motor includes a stator assembly, a rotor assembly, a motor housing and a control board, and the stator assembly, rotor assembly, motor housing and control board are designed according to the above intelligent motor design method.

[0017] A method for correcting the deviation of a motor is disclosed. The method corrects the deviation of the motor using an adaptive tension spring structure designed based on the above-mentioned intelligent motor design method. When the motor rotates at ultra-high speed and causes tilt, the motor on the side close to the motor shaft squeezes the spring, causing the spring to provide a reverse elastic force to the motor side, and the magnitude of the force is positively correlated with the squeezing distance; at the same time, the motor on the side away from the motor shaft stretches the spring, causing the spring to provide a reverse pulling force to the motor side, and the magnitude of the force is positively correlated with the stretching distance, thereby forming a vibration response, the vibration amplitude becomes smaller and smaller, and eventually tends to 0, that is, the correction is to a normal value.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] 1. When a traditional motor moves at high speed, its mechanical parts may rotate or tilt, causing the motor to not be in its normal working point. The present invention can achieve intelligent deviation correction for the motor, allowing the rotor assembly to automatically find balance based on centripetal force during high-speed rotation, thereby ensuring the motor's high-speed performance and reducing losses, ensuring that the motor can operate at ultra-high speed for a long time.

[0020] 2. The present invention can form a specific rotating airflow when the air flows through the inside of the motor, making the air outlet speed higher; the end of the casing is formed with symmetrical hollow positions, so that the rotating air duct of the motor can take away heat through the hollow positions, thereby improving the working power and speed of the motor.

[0021] 3. Traditional cylindrical cores can only use inner winding, and there must be spacing between stator slots, which will result in a low slot fill rate. In order to meet the number of winding turns, the diameter of the enameled wire can only be reduced. When the diameter of the enameled wire is reduced, current overload and motor burnout are easily caused. The design method of the pitch-free stator slots with no spacing and high inner space of the present invention ensures that under the same conditions, there is more winding space, resulting in a higher slot fill rate or the use of thicker enameled wire, thereby increasing the service life of the coil and the motor power, and also supporting the motor to operate at high and ultra-high speeds for a long time.

[0022] 4. The stator core components of the present invention adopt a multi-in-one, zero-spacing design method, and are then stamped into a stator core component array using a high-precision mold in one go, ensuring that each stator core component has a high degree of similarity;

[0023] 5. The M core stator components of the present invention can form a single-phase stator, which can then be combined into, but not limited to, two-phase and three-phase stators. The high-precision symmetrical design ensures that the electrical characteristics of each single-phase stator are highly similar. This high similarity ensures the consistency of the electromagnetic parameters of each phase during motor operation. This enables the motor to operate at ultra-high speeds or in an ultra-quiet state.

[0024] 6. The traditional cylindrical core can only be completed by the inner winding method, and the efficiency of the inner winding production is low. The outer winding coil of the present invention adopts the outer winding method to fix the coil. The tension of the enameled wire is constant during the whole winding process, which solves the problem of the traditional inner winding method that when the coil is bent, the tension of the enameled wire is too large, which damages the tension of the enameled wire and easily causes the coil to short-circuit.

[0037] The present invention will be further described below with reference to specific embodiments.

[0038] Example 1

[0039] The intelligent motor design method provided in this embodiment includes a stator assembly, a rotor assembly, a housing, and a control board. The method includes:

[0040] As shown in Figure 1, a rotor assembly is designed, and two fixed bearings are used to position the magnetic core of the rotor assembly in the middle. A spring is then used to compensate for the distance between the fixed bearings and the magnetic core, so that the magnetic core is restricted from moving between the two bearings, forming an adaptive tension spring structure. This adaptive tension spring structure allows the rotor assembly to automatically find balance according to the centripetal force during ultra-high-speed rotation; the adaptive tension spring structure includes a motor shaft 1, a magnetic core 2 and a spring 3. The magnetic core 2 is mounted on the motor shaft 1, and the spring 2 is mounted on the motor shaft 1 and located at both ends of the magnetic core 2, supporting the movement of the magnetic core 2 from front to back.

[0041] Referring to Figures 2 to 3, a casing is designed in which arc-shaped guide vanes, guide grooves and high-speed fan guide vanes that match the motor are integrally formed, forming a rotating air duct structure suitable for the ultra-high-speed operation of the motor. The air entering the motor is discharged through the rotating air duct structure, and the discharge direction is g, so that the discharged air forms a rotating airflow, the air outlet speed is higher, and the air outlet position can be customized; and a symmetrical hollow position 4 is formed at the end of the casing, so that the motor rotating air duct takes away heat through the hollow position 4, thereby improving the working power and speed of the motor. The symmetrical hollow position 4 at the end of the casing is connected to the tail plate of the motor through a PIN pin for power.

[0042] The rotating air duct structure is integrally formed in the casing, so that the rotating air duct structure as a whole is firmly fixed. Smooth arc-shaped guide vanes are used, and the direction of the arc-shaped guide vanes is consistent with the direction of the air entering the motor, so that the whole is in a diversion operation state, thereby allowing wind to smoothly enter and exit the motor, reducing internal losses, and being suitable for high-speed rotation of the motor. At the same time, bearings are provided in the casing, so that the whole structure is an adaptive magnetic field balancing body with bearings.

[0043] 6 to 12 , a stator assembly is designed, wherein N groups of stator core components are arranged in series and wound without spacing to form a closed structure 12. The closed structure 12 includes a cylindrical structure, which is convenient for generating a customized magnetic field effect to drive the rotor to move. A through stator slot 23 with no spacing is formed in the closed structure 12 to improve the quality and slot fill rate of the outer coil 22. The closed structure 12 is formed with an inner ring wall and an outer ring wall, and both the inner ring wall and the outer ring wall are surrounded by the stator slot 23 with no spacing, thereby wrapping the outer coil 22 inside the closed structure 12 to isolate the outer coil 22 from contact with other motor components. When the motor runs at high speed, the structural vibration of the various parts of the motor will not cause the outer coil 22 to collide and be damaged, and short circuits will be avoided. At the same time, the above significantly improves the processing tolerance, and processing errors during large-scale production will not lead to a decline in the performance of the stator, further improving the consistency and reliability of the product.

[0044] The stator core components are designed in a multi-piece integrated and non-spacing manner. The components of each stator core component are designed and modeled using the copy-paste mode of software modeling to ensure low error of each component, and are stamped into a stator core component array at one time using a high-precision mold, with an error better than 0.005 mm, ensuring high similarity between each stator core component;

[0045] On the outer side of the stator module 11 in each group of stator core components, multiple convex floating patterns 13 are micro-engraved. The total length of the patterns after aligning N groups of stator core components is measured using machine vision detection methods or other common length measurement methods. By calculating the ratio between the total lengths of the patterns of N groups of stator core components, the similarity between N groups of stator core components is obtained; when the similarity is not less than 95%, these N groups of stator core components are used for assembly, and conversely, when the similarity is less than 95%, these N groups of stator core components are not used for assembly to ensure the consistency of each stator core component;

[0046] After N groups of stator core components are aligned, they are wound and assembled into a closed structure 12 using a one-time bending forming process. If the number of bending times exceeds once, the connection between each stator core component will automatically break; among them, the one-time bending forming process includes: a thin connecting piece with multiple hidden micro-reinforcing ribs is designed at the connection of the stator core components, making its combined structure have the characteristic of one-time forming, ensuring that N groups of stator core components are bent into a closed structure 12; at the same time, the rigidity of the reinforcing ribs after bending is further improved, ensuring that the closed structure 12 does not deform due to the movement of the motor;

[0047] M groups of stator core components are used to form a single-phase stator, where M < N. The single-phase stators are combined into two-phase stators, three-phase stators, and up to multi-phase stators. It adopts a high-precision symmetric design process to ensure high similarity between the electrical characteristics of each single-phase stator, and keeps the error of phase resistance not greater than 0.1 ohm and the error of phase inductance not greater than 0.1 microhenry; due to the high similarity between each other, it ensures the consistency of the electromagnetic parameters of each phase when the motor is working, enabling the motor to operate in a super-high-speed state or a super-silent state.

[0048] Among them, each group of stator core components includes a stator module 11, a winding slot 21 sleeved on the stator module 11, an outer-wound coil 22 wound on the winding slot 21, a wiring bracket 32, and a PIN pin 31 installed on the wiring bracket 32, which is the minimum working module of the stator;

[0049] The winding slots 21, the outer winding coils 22 and the non-spacing stator slots 23 constitute a stator auxiliary winding assembly, which is designed to be non-spacing and have a high inner space, ensuring a higher slot fill rate, and is used to support the motor to work at high speed and ultra-high speed for a long time; the non-spacing stator slots 23 are in an I-shaped structure, and the long ends of each non-spacing stator slot 23 are connected to form an outer ring wall without spacing, and the short ends of each non-spacing stator slot 23 are connected to form an inner ring wall. The short ends are protected and the combined outer convexities form a cage-like structure, which ensures that a high inner space is formed between the long end and the short end, which is convenient for the wiring of the outer winding coil 22, so that the slot fill rate reaches the design limit, and is used to support the motor to work at high speed and ultra-high speed for a long time; the wiring bracket 32 ​​is attached to the outer winding coil The starting and ending points of the enameled wire on the coil 22 are used to fix the position of the connecting wire of the externally wound coil 22; the wiring bracket 32 ​​adopts a stepped design, and the diameters at both ends of the wiring bracket 32 ​​are larger than the diameter of the middle part of the wiring bracket 32. The bracket is thick at both ends and thin in the middle, which is convenient for fixing the connecting wire of the externally wound coil 22, so that the connecting wire will not move with the winding needle during the winding process, thereby improving the winding quality. When the motor is running at high speed, this design prevents the displacement of the connecting wire due to up and down vibration, thereby improving the reliability of the coil; at the same time, the externally wound coil 22 is a coil fixed by the external winding method, and the tension of the coil enameled wire is kept constant during the winding process to avoid excessive tension when the coil is bent, which damages the tension of the enameled wire and causes the coil to short-circuit.

[0050] A control board is designed to drive the motor and integrate an active voice noise reduction computing model, which automatically switches between different noise reduction modes according to the environment to achieve noise reduction output. This active voice noise reduction computing model adjusts the ANC controller parameters based on wind noise detection results, optimizing wind noise leakage and rapidly reducing the erroneous signal input to the filter, thereby reducing noise.

[0052] Referring to Figures 4 and 5, the motor provided in this embodiment includes a fan blade a, an adaptive balancing front cover b with a bearing, a rotor assembly c, a stator assembly d, a casing e and a PCB board f, wherein the rotor assembly c, stator assembly d and casing e are designed according to the intelligent motor design method described in Example 1.

[0053] Example 3

[0054] The present embodiment provides a method for correcting the deviation of the motor according to the embodiment 2. This method uses an adaptive tension spring structure designed based on the intelligent motor design method described in embodiment 1 to correct the deviation of the motor. When the motor rotates at ultra-high speed and causes tilt, the motor on the side close to the motor shaft squeezes the spring, causing the spring to provide a reverse elastic force to one side of the motor, and the magnitude of the force is positively correlated with the squeezing distance; at the same time, the motor on the side away from the motor shaft stretches the spring, causing the spring to provide a reverse pulling force to one side of the motor, and the magnitude of the force is positively correlated with the stretching distance, thereby forming a vibration response, and the vibration amplitude becomes smaller and smaller, and eventually tends to 0, that is, the correction is to a normal value.

[0055] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any changes made based on the shape and principle of the present invention should be included in the scope of protection of the present invention.
