Description

Technical Field

[0001] This application relates to the technical field of electric motors, and in particular to a 9-slot 10-pole motor. Background Technology

[0002] In many fields of industrial production and daily life, electric motors, as key equipment for converting electrical energy into mechanical energy, directly affect the operating efficiency and stability of the entire system. Taking CNC machine tools, a typical component processing equipment, as an example, they are widely used in the manufacturing process of various precision parts. Currently, the internal structure of most common motor stator cores is divided into 6-slot, 9-slot, and 12-slot configurations. Although 6-slot motors have advantages in manufacturing cost and processing technology, they are usually difficult to meet the requirements of heavy-load conditions. 9-slot 8-pole motors have a wide range of applications and perform well in many working conditions, but they are prone to radial magnetic pull during operation, leading to motor vibration and causing adverse effects. Although 12-slot motors are widely used in special working environments such as heavy-load conditions, their low slot fill factor and increased winding resistance result in greater resistance loss (higher copper loss), lower slot fill factor, and lower working efficiency.

[0003] Traditional electric motors typically connect the stator assembly and the heat sink housing using screws. This connection method not only obstructs heat dissipation but also leads to a continuous rise in motor operating temperature due to the large amount of heat generated inside the motor and its low heat dissipation efficiency. Excessive temperature accelerates the aging of the internal insulation materials, reduces the motor's insulation performance, increases the risk of short circuits and other malfunctions, and severely impacts the motor's lifespan. Furthermore, high temperatures can cause a decrease in the motor's magnetic properties, further reducing its operating efficiency.

[0004] In terms of structural design, traditional motors have a wider jaw, which not only increases the overall size and space occupied by the motor, but also makes it difficult to improve the magnetic density of the motor. The wider jaw makes the magnetic circuit inside the motor longer and the magnetic reluctance greater, which leads to poorer magnetic field stability of the motor. During operation, it is prone to vibration and noise, affecting the machining accuracy of processing equipment and the working environment. Summary of the Invention

[0005] To address the issues of poor heat dissipation and space utilization in existing motors, this application provides a 9-slot 10-pole motor.

[0006] The 9-slot 10-pole motor provided in this application adopts the following technical solution: A 9-slot 10-pole motor includes a heat sink housing, in which a rotating assembly is rotatably mounted, and a stator assembly is fixedly mounted. The stator assembly is fitted and fixed to the inner side of the heat sink housing. A first insulating bracket and a second insulating bracket are respectively inserted and installed at both ends of the stator assembly, and both the first insulating bracket and the second insulating bracket are fixedly connected to the stator assembly. A protective ring plate is also installed at the outer end of the first insulating bracket, and the protective ring plate is engaged and fixed to the first insulating bracket.

[0007] By adopting the above technical solution, the heat dissipation housing serves as the external structure of the motor body, facilitating the stable installation of the stator and rotating components and ensuring stable rotation during use. Improvements to the stator assembly ensure better contact with the heat dissipation housing, significantly increasing the surface area for close contact. This allows for direct and efficient heat transfer to the housing, achieving excellent heat dissipation and facilitating overall motor cooling. The close-fitting installation of the stator assembly also effectively reduces air gaps and magnetic flux path resistance, increasing the internal magnetic density of the motor, thereby enhancing its operating strength and improving efficiency. This allows the motor to output greater power within the same volume, or to achieve the same power output in a smaller volume. Furthermore, the traditional motor design incorporates a heat dissipation housing to further enhance overall heat dissipation. The 9-slot, 10-pole design ensures stable operation in heavy-duty environments. The first and second insulating supports are used to ensure the stator assembly is securely attached from both ends, providing protection for the stator assembly. By installing a protective ring plate at the outer end of the first insulating bracket, further protection can be provided. At the same time, the way the protective ring plate is engaged and fixed with the first insulating bracket facilitates better installation and use.

[0008] Optionally, the rotating assembly includes a rotating shaft, a positioning seat, and a magnet. The positioning seat is sleeved and fixed on the outer side of the rotating shaft, and the outer side of the positioning seat has 10 sets of positioning grooves along the circumferential direction. The magnet is fixedly installed in the positioning grooves.

[0009] By adopting the above technical solution, the positioning seat in the rotating assembly is fixed to the outer side of the rotating shaft, and 10 sets of positioning slots are opened on the outer side for installing magnets. This structural design makes the installation of magnets more stable, ensuring that the magnets will not shift during motor operation, thereby ensuring the stability of the motor's magnetic field and improving the motor's operating efficiency and performance. At the same time, the arrangement of 10 sets of magnets, in conjunction with the 9-slot stator assembly, enables the motor to operate at high efficiency.

[0010] Optionally, the stator assembly includes a narrow jaw frame, a stator core, and a stator winding. The narrow jaw frame is fitted onto the inner side of the heat sink housing. There are nine sets of stator cores, which are evenly arranged on the inner side of the narrow jaw frame along the circumferential direction. The stator core and the narrow jaw frame are integrally formed. The stator winding is wound on the outer side of the stator core.

[0011] By adopting the above technical solution, the narrow jaw frame of the stator assembly is directly bonded to the inner side of the heat sink housing. Using adhesive or other fastening methods instead of traditional screw connections, this approach allows for better heat transfer with the heat sink housing, significantly improving heat dissipation and reducing the risk of motor damage due to overheating. Furthermore, eliminating screw holes optimizes the jaw width, allowing for design optimization of jaw parameters, increasing the motor's magnetic density, and thus enhancing its operational strength and efficiency. Nine sets of stator cores are evenly arranged circumferentially on the inner side of the narrow jaw frame and integrally formed with it, making stator winding more convenient and stable, further improving motor performance.

[0012] Optionally, the first insulating support includes an outer ring frame and a plug-in shell sleeved on the outside of the stator winding. The plug-in shell is evenly arranged on one side of the outer ring frame along the circumferential direction, and the plug-in shell is integrally formed with the outer ring frame. The other side of the outer ring frame is provided with several sets of elastic locking plates for locking the protective ring plates.

[0013] By adopting the above technical solution, the outer ring frame and the plug-in shell of the first insulating support are integrally formed. The plug-in shell is sleeved on the outside of the stator winding, which can provide good insulation protection for the stator winding and prevent safety accidents such as leakage. The elastic locking plate on the outer ring frame is used to lock the protective ring plate, making the installation of the protective ring plate more secure and further enhancing the protection effect on the stator winding.

[0014] Optionally, the heat dissipation housing includes a main housing, a cooling housing, and a tail cover. The cooling housing is installed between the main housing and the tail cover, and the cooling housing is sealed and fixedly connected to both the main housing and the tail cover. An auxiliary cover is also fastened to the outer end of the tail cover and is fixedly connected to the tail cover. An inner cover is installed on the inner side of the cooling housing and is rotatably sealed to the cooling housing. A drive cylinder for driving the inner cover to rotate is installed at the lower end of the cooling housing, and an air supply assembly is also fixedly installed at the lower end of the cooling housing.

[0015] By adopting the above technical solution, the heat dissipation housing uses a combination structure of a main housing, a cooling housing, and a tail cover. The cooling housing is installed between the main housing and the tail cover, and internally it is equipped with an inner sealing shell, a drive cylinder, and an air supply assembly, forming a highly efficient heat dissipation system. The cool air supplied by the air supply assembly enters the cooling housing through the air inlet. The inner sealing shell rotates under the drive of the drive cylinder, allowing the cool air to be blown evenly into the motor, thus improving heat dissipation efficiency.

[0016] Optionally, the cooling shell includes a base shell, a side arc mesh shell, a connecting lug, and a top arc mesh plate. The side arc mesh shell is installed at both ends of the base shell, and the lower end of the side arc mesh shell is fixed to the base shell. The connecting lug is fixedly installed at the head of the side arc mesh shell. The top arc mesh plate is disposed above the connecting lug, and both ends of the top arc mesh plate are fixedly connected to the connecting lug.

[0017] By adopting the above technical solution, the structural design of the cooling shell's base shell, side arc mesh shell, connecting lugs, and top arc mesh plate not only ensures the overall strength of the cooling shell but also provides space for the installation and rotation of the inner shell. In actual installation, the side arc mesh shell is fixedly installed at both ends of the base shell, facilitating side ventilation through the side arc mesh shell. The connecting lugs are fixedly installed on the side arc mesh shell, allowing the cooling shell to be connected and fixed to the main shell. Finally, the top arc mesh plate is fixedly installed on the top of the connecting lugs, facilitating top ventilation through the top arc mesh plate during use.

[0018] Optionally, both sides of the inner side of the base shell and the connecting ear seat are provided with arc-shaped baffles for limiting the inner sealing shell, and sealing rings are installed at both ends of the outer side of the inner sealing shell, and the sealing rings are fixedly connected to the inner sealing shell.

[0019] By adopting the above technical solution, by setting arc-shaped baffles on both sides of the inner side of the base shell and the connecting ear, the inner shell can be stably rotated after it is fitted onto the inner side of the base shell and the connecting ear. Then, by installing sealing rings at both ends of the outer side of the inner shell, the inner shell can be sealed and rotated with the cooling shell. Thus, the rotation of the inner shell can achieve the purpose of closing and opening for ventilation.

[0020] Optionally, the base shell is provided with an air inlet corresponding to the air supply component, and the side arc mesh shell and the top arc mesh plate are provided with a number of ventilation holes arranged in rows along the circumferential direction.

[0021] By adopting the above technical solution, the ventilation holes on the side arc mesh shell and the top arc mesh plate are conducive to the discharge of hot air, while the air inlet on the base shell corresponds to the air supply component, which can ensure the smooth entry of cold air, thereby achieving efficient heat dissipation.

[0022] Optionally, the inner casing includes a bottom arc plate and an arc-shaped sealing plate. The arc-shaped sealing plate is installed on the upper end of the bottom arc plate, and both ends of the arc-shaped sealing plate are fixedly connected to the bottom arc plate. The bottom arc plate has a mating groove corresponding to the air inlet. The length of the mating groove is greater than the length of the air inlet. A mating swing rod that is rotatably connected to the output end of the drive cylinder is fixedly installed on the lower end face of the bottom arc plate. The arc-shaped sealing plate has strip grooves evenly provided corresponding to each row of vent holes.

[0023] By adopting the above technical solution, the length of the mating groove on the bottom arc plate of the inner shell is greater than the length of the air inlet, ensuring that sufficient cold air always enters during rotation. The strip grooves on the arc plate correspond to the vent holes. When the strip grooves are aligned with the rows of vent holes, high-speed ventilation is achieved; when the strip grooves are misaligned with the rows of vent holes, closure is achieved. When the inner shell rotates for adjustment, the vent holes can be opened and closed, facilitating switching between activating and deactivating the air supply component. By fixing a mating swing rod to the lower end face of the bottom arc plate, it is easy to connect to the drive cylinder, allowing the inner shell to be rotated via the drive cylinder during use.

[0024] Optionally, the air supply assembly includes an external bracket and a cooling fan. The external bracket is fixedly installed on the lower end face of the base shell, and the cooling fan is fixedly installed in the external bracket.

[0025] By adopting the above technical solution, the external bracket of the air supply component is fixed to the lower end face of the base shell, and the cooling fan is fixed in the external bracket, which can stably provide cold air to the cooling shell and ensure the normal operation of the heat dissipation system.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By improving the connection method between the stator assembly and the heat sink housing and setting up a high-efficiency heat sink housing structure, this application greatly improves the heat dissipation efficiency of the motor. The tight fit between the narrow jaw frame and the heat sink housing, as well as the cooperation between the air supply component and the inner shell inside the heat sink housing, can dissipate the heat generated by the motor in a timely manner, reduce the operating temperature of the motor, and extend the service life of the motor. At the same time, by eliminating the traditional screw connection method, the jaw width is optimized, improving the magnetic density and operating efficiency of the motor. Furthermore, the structural design of each component is more reasonable, installation is more convenient, and the overall size and space occupied by the motor are reduced. The setting of the first insulating bracket and the protective ring plate provides good insulation and protection for the stator winding, improving the safety and stability of the motor. The reasonable design of the rotating assembly and the stator assembly forms a 9-slot 10-pole motor, ensuring the magnetic field stability and operating efficiency of the motor, making the motor run more smoothly and reducing vibration and noise.

The stator assembly 3 is fitted and fixed to the inner surface of the heat sink housing 1. A first insulating bracket 4 and a second insulating bracket 5 are respectively inserted and installed at both ends of the stator assembly 3, and both the first insulating bracket 4 and the second insulating bracket 5 are fixedly connected to the stator assembly 3. A protective ring plate 40 is also installed at the outer end of the first insulating bracket 4, and the protective ring plate 40 is engaged and fixed to the first insulating bracket 4. By using the heat sink housing 1 as the external structure of the motor body, it is convenient to stably install the stator assembly 3 and the rotating assembly 2, and to ensure stable rotation during use. By improving the stator assembly 3, it is ensured to better fit the heat sink housing 1 during use, and the surface area of ​​close contact is greatly increased, which is conducive to the direct and efficient transfer of heat to the heat sink housing 1, achieving excellent heat dissipation effect and facilitating the overall heat dissipation of the motor. The tight fit of the stator assembly 3 effectively reduces air gap and magnetic flux path resistance, increasing the internal magnetic density of the motor and thus enhancing its operating strength and efficiency. This allows the motor to output greater power within the same volume, or to achieve the same power output in a smaller volume. Furthermore, the traditional motor can be designed as a heat dissipation housing 1, further improving overall heat dissipation. Simultaneously, designing the motor as a 9-slot, 10-pole motor ensures stable operation in heavy-duty environments. The first insulating bracket 4 and the second insulating bracket 5 are used to ensure insertion into the stator assembly 3 from both ends, providing protection for the stator assembly 3. A protective ring plate 40 is installed at the outer end of the first insulating bracket 4, further enhancing protection. The engaging and securing mechanism of the protective ring plate 40 with the first insulating bracket 4 facilitates easier installation and use.

This structural design makes the installation of the magnets 23 more stable, ensuring that the magnets 23 will not shift during motor operation, thereby ensuring the stability of the motor's magnetic field and improving the motor's operating efficiency and performance. At the same time, the arrangement of 10 sets of magnets 23, in conjunction with the 9-slot stator assembly 3, enables the motor to operate at high efficiency.

The stator cores 32 and the narrow jaw frame 31 are integrally formed. The stator windings are wound on the outer side of the stator cores 32. The narrow jaw frame 31 of the stator assembly 3 is directly fitted and fixed to the inner side of the heat sink housing 1. The traditional screw connection is replaced by a fastening method such as glue. On the one hand, it can better transfer heat with the heat sink housing 1, greatly improve the heat dissipation effect, and reduce the risk of motor damage due to overheating. On the other hand, the elimination of screw holes optimizes the jaw width, allowing for design optimization of jaw parameters, improving the magnetic density of the motor, and thus enhancing the working strength and efficiency of the motor. Nine sets of stator cores 32 are evenly arranged along the circumferential direction on the inner side of the narrow jaw frame 31 and integrally formed with it, which makes the winding of the stator winding more convenient and stable, and further improves the performance of the motor.

The plug-in shell 42, fitted around the stator winding, provides good insulation protection for the stator winding, preventing safety accidents such as leakage. The elastic locking plates 411 on the outer ring frame 41 are used to lock the protective ring plates 40, making the installation of the protective ring plates 40 more secure and further enhancing the protection effect on the stator winding.

The cold air supplied by the air supply assembly 8 enters the cooling shell 12 through the air inlet 126. The inner shell 6 rotates under the drive of the electric cylinder 7, so that the cold air can be blown evenly into the motor, improving the heat dissipation efficiency.

The assembled rotating assembly 2 is inserted into the main housing 11, ensuring that the rotating assembly 2 can be rotatably installed within the main housing 11. Then, the stator assembly 3 is installed. A suitable narrow jaw frame 31 is selected, made of silicon steel sheets to improve the magnetic performance of the motor. Nine sets of stator cores 32 are evenly arranged circumferentially on the inner surface of the narrow jaw frame 31. Since the stator cores 32 and the narrow jaw frame 31 are integrally formed, they can be manufactured using processes such as stamping. The stator winding is wound on the outer surface of the stator core 32. High-strength enameled wire can be used for the stator winding to improve the electrical performance of the motor.

After the inner sealing shell 6, the drive cylinder 7 and the air supply assembly 8 are installed on the cooling shell 12, the heat dissipation housing 1 can be assembled. The cooling shell 12 is installed between the main housing 11 and the tail cover 13 and fixed together with long bolts. After assembly, attach the auxiliary cover 131 to the outer end of the tail cover 13 to complete the overall assembly of the motor.
