Description

Technical Field

[0001] This application relates to the field of conveying device technology, and more specifically, to a stator module and a conveying system. Background Technology

[0002] In related technologies, the conveying system includes a stator module and a mover module. The stator module and the mover module are magnetically coupled to drive the mover module to move. However, the stator module is easily affected by external environment (such as metal components near the conveying system, magnetic fields of other motors) or its own current fluctuations, resulting in poor magnetic field stability. Utility Model Content

[0003] This application provides a stator module and a conveying system, which aim to enhance magnetic field stability and reduce manufacturing costs.

[0004] The first aspect of this application provides a stator module, which includes a stator base and a stator assembly. The stator base has a top guide rail wall, a first side wall, and a second side wall. The first side wall and the second side wall are located below the top guide rail wall and are arranged opposite to each other along the width direction of the stator base. The first side wall is recessed with a mounting groove in the direction facing the second side wall. The stator assembly includes a stator core and a stator winding wound on the stator core. A portion of the stator core and the stator winding are located inside the mounting groove, and the remaining portion is located outside the mounting groove.

[0005] In some embodiments, the stator core has a through hole, and the stator module further includes a screw connector that passes through the through hole and is screwed to the bottom wall of the mounting groove to fix the stator core to the bottom wall of the mounting groove.

[0006] In some embodiments, the stator base further includes a receiving cavity formed by the top guide wall, the first side wall, and the second side wall. The stator module further includes a driver, which includes a circuit integrated board and a connector electrically connected to the circuit integrated board. The circuit integrated board is located within the receiving cavity and electrically connected to the stator winding. The connector is at least partially located outside the receiving cavity.

[0007] In some embodiments, the stator base further has a first receiving cavity, which communicates with the receiving cavity, and the plug is at least partially located within the first receiving cavity; in the direction from the top to the bottom of the stator base, the second sidewall includes a first sub-wall, an inclined transition wall, and a second sub-wall connected in sequence, and along the width direction, the second sub-wall protrudes relative to the first sub-wall, and the inclined transition wall is inclinedly connected between the first sub-wall and the second sub-wall, wherein the first receiving cavity is formed by the second sub-wall being recessed towards the first sidewall, and the second sub-wall has an opening for the first receiving cavity.

[0008] In some embodiments, the stator module further includes a sensor array component disposed on the first sub-wall and located above the inclined transition wall and the second sub-wall.

[0009] In some embodiments, the stator base further includes a first vent located on the second sub-wall and communicating with the opening; and / or, the stator module further includes a cover plate covering the opening, the cover plate having a second vent penetrating the cover plate to communicate with the first receiving cavity.

[0010] In some embodiments, the cover plate includes a cover body and two snap-fit ​​portions, the two snap-fit ​​portions being connected to the upper and lower ends of the cover body respectively; wherein, when the cover plate is placed over the opening, the two snap-fit ​​portions pass through the opening and snap into the groove wall of the first receiving cavity.

[0011] In some embodiments, the second sidewall also has two grooves, which are located on the upper and lower sides of the opening and communicate with the opening; the cover plate also includes two protrusions, which are located at the upper and lower ends of the cover body and protrude relative to the adjacent snap-fit ​​portion in the vertical direction; wherein, when the cover plate covers the opening, the protrusions extend into the grooves so that the outer surface of the cover body does not protrude from the second sub-wall.

[0012] A second aspect of this application provides a conveying system, which includes a stator module and a mover module as described in any of the above claims. The number of stator modules is multiple, and the multiple stator modules are spliced ​​together to form a stator conveying line. The mover module includes a mover base and a permanent magnet. The mover base is slidably connected to the stator module, and the permanent magnet is disposed on the mover base and magnetically coupled to the stator assembly.

[0013] In some embodiments, the stator module further includes a first guide rail and a second guide rail. The first guide rail is disposed on the top guide rail wall and extends along the conveying direction of the stator conveyor line. The second guide rail is disposed on the first side wall and located below the mounting groove, and extends along the conveying direction. The mover base includes a first sliding member and a second sliding member. The first sliding member is slidably engaged with the first guide rail, and the second sliding member is slidably engaged with the second guide rail.

[0014] This embodiment of the application features a mounting groove on the first sidewall, with a portion of the stator core and stator winding located within the groove and the remainder outside. This allows the stator core and the remaining portion of the stator winding to be close to the permanent magnet, improving magnetic coupling efficiency. Furthermore, the laminated structure of the stator core reduces magnetic field diffusion, resulting in a more uniform and stable air gap magnetic field distribution and reduced susceptibility to external environmental interference, thus enhancing magnetic field stability. The stator core can transform a disordered magnetic field into a highly efficient directional magnetic circuit, increasing thrust and enabling rapid control of the start-up or shutdown of the rotor module. Moreover, compared to stator assemblies without a stator core, the stator assembly of this embodiment includes a stator core, typically constructed from standardized laminated silicon steel sheets. The stator windings can be wound onto the stator core using automated equipment. Since silicon steel sheets are common industrial materials, their cost is lower than that of special materials like epoxy resin required without a stator core, thereby reducing manufacturing costs.

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Please see Figures 1-2 This application provides a conveying system 100, which is an integrated system that uses mechanical, electrical, and automated control technologies to transfer materials from one spatial location to another.

[0020] The conveying system 100 includes a stator module 10 and a mover module 20.

[0021] Specifically, there are multiple stator modules 10, which are spliced ​​together to form a stator conveyor line 30. The stator conveyor line 30 is used to drive and guide the movement of the mover module 20. That is, the mover module 20 can move along the conveying direction of the stator conveyor line 30. The stator conveyor line 30 formed by splicing multiple stator modules 10 can be a straight stator conveyor line 30, an arc stator conveyor line 30, or a loop stator conveyor line 30. This application embodiment does not specifically limit this.

[0022] Furthermore, this application embodiment does not specifically limit the way stator modules 10 are spliced ​​together. For example, bridging slots 50 are provided at both ends of the stator module 10 along the conveying direction, that is, the number of bridging slots 50 for each stator module 10 is at least two. The conveying system 100 also includes a bridging component 40, with both ends of the bridging component 40 respectively disposed in the two bridging slots 50 of different stator modules 10. It can be understood that multiple stator modules 10 can be connected to each other through the bridging component 40. That is, one end of the bridging component 40 is installed in one of the bridging slots 50 and can be installed on one of the stator modules 10 by screws, and the other end of the bridging component 40 is installed in the bridging slot 50 of another stator module 10 and can be installed on another stator module 10 by screws, thereby realizing the connection between adjacent stator modules 10. Since adjacent stator modules 10 are connected through the bridging component 40, the convenience of installation between stator modules 10 is improved.

[0023] Furthermore, the bridging groove 50 is formed on the top guide rail wall 111 of the stator base 11, and the bridging component 40 is installed in the bridging groove 50 and locked to the stator base 11 by screws. In this way, the installation accuracy between the stator modules 10 is improved.

[0024] It should be noted that the embodiments of this application do not specifically limit the shape of the bridging groove 50 and the shape of the bridging component 40, but the bridging component 40 needs to be able to be installed in the bridging groove 50. For example, the shape of the bridging groove 50 can be rectangular or square.

[0025] Please continue reading. Figures 1-2 The mover module 20 includes a mover base 21 and a permanent magnet 22. The mover base 21 is slidably connected to the stator module 10, and the permanent magnet 22 is disposed on the mover base 21 and magnetically coupled to the stator module 10. It can be understood that the mover base 21 has a bearing surface capable of supporting the material to be conveyed. Under the influence of the magnetic field generated by the stator module 10, the permanent magnet 22 on the mover base 21 is pushed by electromagnetic force, thereby driving the mover base 21 and the material mounted on the bearing surface to move together, realizing the conveying of the material along the conveying direction of the stator conveyor line 30.

[0026] The stator module 10 will be described in detail below.

[0027] The stator module 10 includes a stator base 11 and a stator assembly 12.

[0028] Please continue reading. Figures 1-2The stator base 11 has a top guide rail wall 111, a first side wall 112 and a second side wall 113. The first side wall 112 and the second side wall 113 are located below the top guide rail wall 111 and are arranged opposite to each other along the width direction of the stator base 11. That is, the top guide rail wall 111 is connected to the first side wall 112 and the second side wall 113 on both sides in the width direction, and the first side wall 112 has a mounting groove 112A, that is, the first side wall 112 is recessed in the direction of the second side wall 113.

[0029] The top guide rail wall 111, the first side wall 112, and the second side wall 113 can be integral components to reduce assembly steps; or, the top guide rail wall 111, the first side wall 112, and the second side wall 113 can be spliced ​​together to form the stator base 11.

[0030] The stator assembly 12 includes a stator core and a stator winding, with the stator winding wound on the stator core. It is understood that a portion of the stator core and stator winding is located within the mounting slot 112A, while the remaining portion is located outside the mounting slot 112A. This serves two purposes: firstly, embedding a portion of the stator core and stator winding into the mounting slot 112A provides mechanical fixation, preventing the stator assembly 12 from loosening; secondly, exposing the remaining portion of the stator core and stator winding outside the mounting slot 112A shortens the distance to the permanent magnet 22, thereby reducing the air gap magnetic field, improving magnetic coupling efficiency, and lowering magnetic field loss.

[0031] The stator core and stator windings are the core functional components of electromagnetic drives. The stator core is made of a high-permeability material, which significantly enhances the magnetic field strength. Furthermore, the stator core is typically made of low-loss silicon steel sheets, reducing eddy current losses and hysteresis losses. In addition, the stator core is also a highly efficient heat dissipation carrier; that is, the stator core is usually made of low-loss silicon steel sheets, which have excellent thermal conductivity, allowing the heat generated by the stator windings to be quickly transferred through the stator core to the external heat sink, effectively improving heat dissipation.

[0032] In this embodiment, the first sidewall 112 has a mounting groove 112A, with the stator core and part of the stator winding located inside the mounting groove 112A and the rest outside. This allows the stator core and the remaining part of the stator winding to be close to the permanent magnet 22, improving magnetic coupling efficiency. Furthermore, the laminated structure of the stator core reduces magnetic field diffusion, making the air gap magnetic field distribution more uniform and stable, and reducing interference from the external environment, thereby enhancing magnetic field stability. The stator core can tame a disordered magnetic field into a highly efficient directional magnetic circuit, increasing thrust and enabling rapid control of the start-up or shutdown of the mover module 20. Moreover, compared to a stator assembly 12 without a stator core, the stator assembly 12 in this embodiment includes a stator core, which is typically made of standardized silicon steel sheets laminated together. The stator winding can be wound onto the stator core using automated equipment. Silicon steel sheets are common industrial materials, and their cost is lower than that of special materials such as epoxy resin required without a stator core, thus reducing manufacturing costs.

[0033] It should be noted that the stator base 11 and the mover base 21 are usually made of materials with good rigidity and strength so that the stator base 11 and the mover base 21 are not easily bent or broken under external force, such as steel, aluminum alloy, etc. This application embodiment does not make specific limitations in this regard.

[0034] Please see Figure 2 The stator module 10 also includes a sensor array component 17, which is disposed on the second side wall 113; the mover module 20 also includes a sensing component 25, which is disposed on the mover base 21 and is disposed opposite to the sensor array component 17. In the width direction, the sensing component 25 and the sensor array component 17 are spaced apart, so that the sensor array component 17 can read the signal generated by the sensing component 25 at all times to obtain the movement position of the mover module 20.

[0035] The sensing component 25 and the sensor array component 17 are spaced apart, meaning there is a non-contact signal connection between them. The sensing component 25 can send signals to the sensor array component 17. This embodiment does not specifically limit the types of the sensing component 25 and the sensor array component 17. For example, the sensor array component 17 may include an optical encoder array or a magnetic encoder array, and the sensing component 25 may include a magnetic encoder or an optical encoder. By reading the signals emitted by the sensing component 25 through the sensor array component 17, the position of the stator base 21 is determined, and the corresponding stator winding is controlled to periodically energize. Furthermore, since the sensor array component 17 is located on the second sidewall 113 and the stator assembly 12 is located on the first sidewall 112, the height of the stator base 11 can be effectively reduced in the vertical direction.

[0036] In some embodiments, the first sidewall 112 is recessed toward the second sidewall 113 to form a mounting groove 112A, and the mounting groove 112A does not extend upward through the top guide rail wall 111. It is understood that the mounting groove 112A is located at the middle of the first sidewall 112, so that when the stator core and stator windings are partially embedded in the mounting groove 112A, the wall surface of the mounting groove 112A can provide support for the stator core and stator windings, preventing the stator assembly 12 from loosening due to vibration of the conveying system 100, thus ensuring the stability of the mover module 20's movement. Furthermore, since the stator base 11 needs to simultaneously support the mover module 20 and fix the stator assembly 12, the overall structural strength of the stator base 11 is ensured by setting the mounting groove 112A not to extend upward through the top guide rail wall 111.

[0037] In some embodiments, the stator core has a through hole, and the stator module 10 further includes a screw connector. The screw connector passes through the through hole and is screwed into the bottom wall of the mounting groove 112A. That is, after the screw connector passes through the through hole of the stator core, it engages with the threaded hole on the bottom wall of the mounting groove 112A to fix the stator core to the bottom wall of the mounting groove 112A. The stator core and the stator base 11 can be independently processed and then quickly assembled by the screw connector to shorten the production cycle.

[0038] Please see Figures 1-2 In some embodiments, the stator module 10 further includes a first guide rail 15, which is disposed on the top guide rail wall 111 and extends along the conveying direction of the stator conveying line 30; that is, the first guide rail 15 can be connected to the top guide rail wall 111 by means of screwing, welding, bonding or snapping to fix the first guide rail 15 on the stator base 11; or, the first guide rail 15 can also be fixed to the stator base 11 by integral injection molding to reduce assembly steps.

[0039] The mover base 21 includes a first sliding member 23, which is slidably engaged with the first guide rail 15. In this way, the mover module 20 can slide on the first guide rail 15 to realize the movement of the mover module 20 along the conveying direction of the stator conveyor line 30.

[0040] Please continue reading. Figures 1-2Furthermore, the stator module 10 also includes a second guide rail 16, which is disposed on the first side wall 112 and located below the mounting groove 112A, and extends along the conveying direction. That is, the second guide rail 16 can be connected to the first side wall 112 by means of screwing, welding, bonding, or snap-fitting to fix the second guide rail 16 to the stator base 11; or, the second guide rail 16 can also be fixed to the stator base 11 as a whole by integral injection molding to reduce assembly steps. The mover base 21 also includes a second sliding member 24, which slides in engagement with the second guide rail 16. In this way, with the first guide rail 15 and the first sliding member 23 sliding in engagement, the sliding engagement of the second guide rail 16 and the second sliding member 24 further increases the stability of the mover module 20 moving on the stator conveyor line 30.

[0041] The second guide rail 16 is located below the mounting groove 112A, so that when the stator winding is magnetically coupled to the permanent magnet 22, it will not interfere with the sliding engagement of the second guide rail 16 and the second sliding member 24.

[0042] Please continue reading. Figures 1-2 In some embodiments, the stator module 10 further includes a blocking member 18, which is disposed on at least one of the top guide rail wall 111 and the first side wall 112. That is, the blocking member 18 may be disposed on the top guide rail wall 111, or the blocking member 18 may be disposed on the first side wall 112, or the blocking member 18 may be disposed on both the top guide rail wall 111 and the first side wall 112. The blocking member 18 is disposed adjacent to the first guide rail 15 or the second guide rail 16. Along the conveying direction, the blocking member 18 is located on at least one of the end and the beginning of the stator conveying line 30. It is understandable that during the process of the stator winding and the permanent magnet 22 of the mover module 20 being magnetically coupled to drive the mover module 20 to move along the conveying direction of the stator conveying line 30, the mover module 20 is prone to derailment at the end or beginning of the stator conveying line 30 in an uncontrolled state. Therefore, by providing a blocking member 18 on at least one of the top guide rail wall 111 and the first side wall 112, and the blocking member 18 being located at at least one of the end or beginning of the stator conveying line 30, the mover module 20 is prevented from derailing in an uncontrolled state, thereby ensuring the safety of the conveying system 100.

[0043] Furthermore, the blocking member 18 is detachably disposed on at least one of the top guide rail wall 111 and the first side wall 112. For example, when the blocking member 18 is detachably disposed on the top guide rail wall 111 and the blocking member 18 is located at the end and the beginning of the stator conveying section along the conveying direction, the blocking member 18 is usually detachably disposed on the top guide rail wall 111 so that the mover module 20 can be disengaged from the first guide rail 15, thereby facilitating the maintenance of the mover module 20.

[0044] It should be noted that this application embodiment does not specifically limit the connection method between the blocking member 18 and the top guide rail wall 111 or the first side wall 112. Exemplarily, the blocking member 18 can be fixed to the top guide rail wall 111 or the first side wall 112 by means of screwing, snap-fitting, or magnetic attraction. Furthermore, this application embodiment does not specifically limit the material used to manufacture the blocking member 18.

[0045] Please see Figure 2 In some embodiments, the stator base 11 further includes a receiving cavity 11A, which is formed by a top guide rail wall 111, a first side wall 112, and a second side wall 113. The stator module 10 also includes a driver and a fan, with portions of the driver and the fan located within the receiving cavity 11A for protection. Further, the driver includes a circuit board 60 and a connector 70 electrically connected to the circuit board 60. The circuit board 60 is located within the receiving cavity 11A and electrically connected to the stator windings, while the connector 70 is at least partially located outside the receiving cavity 11A to facilitate electrical connection of cables to the connector 70.

[0046] Please see Figures 2-3 In some embodiments, the stator base 11 further has a first receiving cavity 114, which communicates with the receiving cavity 11A, and the plug-in 70 is at least partially located in the first receiving cavity 114, that is, the plug-in 70 may be partially located in the receiving cavity 11A and the other part located in the first receiving cavity 114; or, the plug-in 70 may be entirely located in the first receiving cavity 114, so as to reduce damage to the plug-in 70 and extend the service life of the plug-in 70.

[0047] The opening 115 of the first receiving cavity 114 is disposed away from the first sidewall 112; that is, the position of the opening 115 of the first receiving cavity 114 is opposite to the slot opening of the mounting groove 112A. This avoids interference of the opening 115 of the first receiving cavity 114 with the movement of the moving module 20. The first receiving cavity 114 is disposed below the sensor array component 17. Furthermore, since both the sensor array component 17 and the opening 115 of the first receiving cavity 114 are disposed on the second sidewall 113, the thickness of the sensor array component 17 is less than the thickness of the first receiving cavity 114 in the width direction. Thus, when the sensor array component 17 cooperates with the sensing component 25, the width of the moving module 20 can be reduced due to the smaller thickness of the sensor array component 17, thereby achieving miniaturization of the moving module 20.

[0048] The stator module 10 also includes a cover plate 13, wherein the connector 70 is disposed within the first receiving cavity 114, and the cover plate 13 covers the opening 115. This application embodiment does not specifically limit the material of the cover plate 13. Exemplarily, the material of the cover plate 13 can be plastic, metal, or composite material, etc. When the cover plate 13 is made of metal, it can improve the electromagnetic shielding effect to suppress interference from external electromagnetic fields on the connector 70.

[0049] Furthermore, the first receiving cavity 114 and the mounting groove 112A are at least partially offset in the width direction. It is understood that the projections of the first receiving cavity 114 and the mounting groove 112A in the width direction do not completely overlap. This serves two purposes: firstly, it fully utilizes the space of the stator base 11, making the structure of the stator module 10 more compact; secondly, it ensures the overall support of the stator base 11 for the mover module 20. That is, the at least partial offset of the first receiving cavity 114 and the mounting groove 112A in the width direction reduces the problem of local stress concentration in the stator base 11.

[0050] Please see Figure 4 In the direction from the top to the bottom of the stator base 11, the second sidewall 113 includes a first sub-wall 116, an inclined transition wall 117, and a second sub-wall 118 connected in sequence. It is understandable that, since the first sidewall 112 is provided with a mounting groove 112A, and in order to ensure that the stator base 11 can still support the mover module 20, the second sidewall 113 is provided with a first receiving cavity 114 so that the plug-in 70 is at least partially disposed in the first receiving cavity 114; therefore, in this embodiment of the application, the second sub-wall 118 is provided to protrude relative to the first sub-wall 116 along the width direction, and the inclined transition wall 117 is inclinedly connected between the first sub-wall 116 and the second sub-wall 118; that is, in the width direction, the distance from the first sub-wall 116 to the first sidewall 112 is smaller than the distance from the second sub-wall 118 to the first sidewall 112, and the inclined transition wall 117 connects the first sub-wall 116 and the second sub-wall 118, wherein the first receiving cavity 114 is formed by the second sub-wall 118 being recessed towards the first sidewall 112, and the opening 115 of the first receiving cavity 114 is provided on the second sub-wall 118.

[0051] Furthermore, when the cover plate 13 is placed over the opening 115, the cover plate 13 can be formed as part of the surface of the second sub-wall 118. That is, the second sub-wall 118 can be divided into a cover plate sidewall and a connecting sidewall. The cover plate sidewall is the wall surface formed by the surface of the cover plate 13, and the connecting sidewall is the wall surface of the second sub-wall 118 other than the cover plate sidewall. At this time, the second sidewall 113 includes the first sub-wall 116, the inclined transition wall 117, the cover plate sidewall, and the connecting sidewall. Based on the above, the second sub-wall 118 protrudes relative to the first sub-wall 116 along the width direction. The inclined transition wall 117 is inclined and connected between the first sub-wall 116 and the second sub-wall 118. Therefore, the second sidewall 113 is an irregular structure as a whole to ensure the overall structural strength of the stator base 11.

[0052] Furthermore, since the second sidewall 113 includes a first sub-wall 116, an inclined transition wall 117, and a second sub-wall 118 connected in sequence in the direction from the top to the bottom of the stator base 11, and the first receiving cavity 114 is formed by the second sub-wall 118 recessed towards the first sidewall 112, the sensor array component 17 is disposed on the first sub-wall 116 and located above the inclined transition wall 117 and the second sub-wall 118, so as to avoid the cable electrically connected to the connector 70 in the first receiving cavity 114 from affecting the sensor array component 17 and the sensing component 25.

[0053] Please see Figure 3 In some embodiments, the cover plate 13 includes a cover body 131 and two snap-fit ​​portions 132. The cover body 131 is used to cover the opening 115 of the first receiving cavity 114, and is typically flat or thin-shell shaped. The two snap-fit ​​portions 132 are respectively connected to the upper and lower ends of the cover body 131. It can be understood that when the cover plate 13 is placed over the opening 115, the two snap-fit ​​portions 132 pass through the opening 115 and snap into the groove wall of the first receiving cavity 114. That is, when the cover plate 13 moves axially along the opening 115, the snap-fit ​​portions 132 undergo elastic deformation due to the pressure of the groove wall. After the snap-fit ​​portion 132 passes through the groove wall, the elastic restoring force causes it to expand outward, forming an interference fit or hook connection with the groove wall. In this way, after the cover body 131 completely covers the opening 115, the snap-fit ​​portions 132 bear the separation force perpendicular to the opening 115, preventing the cover plate 13 from falling off, thereby realizing the assembly of the cover plate 13 onto the second side wall 113. It should be noted that the cover body 131 and the two snap-fit ​​parts 132 are integral components to enhance the structural strength of the cover plate 13.

Figure 3Furthermore, in some embodiments, the second sidewall 113 also has two grooves 119, which are located on the upper and lower sides of the opening 115 and communicate with the opening 115; the cover plate 13 also includes two protrusions 133, which are located at the upper and lower ends of the cover body 131; that is, in the vertical direction, the two protrusions 133 protrude from the cover body 131, so that when the cover plate 13 is placed over the opening 115, the protrusions 133 extend into the grooves 119, so that the outer surface of the cover body 131 does not protrude from the second sub-wall 118, that is, the outer surface of the cover body 131 is flush with the second sub-wall 118, so as to avoid the stator module 10 occupying too much space. In addition, the shape of the grooves 119 and the protrusions 133 can restrict the installation direction of the cover plate 13 to avoid reverse installation or misalignment.

[0055] It should be noted that the protrusion 133, the cover body 131, and the snap-fit ​​part 132 in this embodiment of the application can be an integral component to reduce assembly steps and improve the structural strength of the cover plate 13.

[0056] Please see Figure 4 In some embodiments, the stator base 11 also has a first vent 14, which is located on the second sub-wall 118 and is connected to the opening 115. That is, the first vent 14 is connected to the first receiving cavity 114, and a connector 70 is provided in the first receiving cavity 114. When working, the connector 70 will generate heat, and external air is introduced through the first vent 14 to form a heat dissipation path that guides the heat to the outside through the first receiving cavity 114 and the first vent 14, so as to reduce the temperature of the connector 70.

[0057] Furthermore, a fan is installed inside the accommodating cavity 11A of the stator base 11, and an air duct is formed between the fan and the first ventilation port 14 to accelerate the heat dissipation of the circuit integrated board 60 and the connector 70.

[0058] In other embodiments, the cover plate 13 has a second vent that extends through the cover plate 13; that is, the second vent communicates with the first receiving cavity 114. Thus, during operation, the connector 70 generates heat, and external air is introduced through the first vent 14 to form a heat dissipation path that guides the heat to the outside through the first receiving cavity 114 and the first vent 14, thereby reducing the temperature of the connector 70. Multiple second vents are used to improve heat dissipation efficiency. A heat dissipation airflow is formed between the aforementioned fan and the second vents to accelerate the heat dissipation of the circuit board 60 and the connector 70.

[0059] In some other embodiments, the stator base 11 also has a first vent 14 located on the second sub-wall 118, and the first vent 14 is connected to the opening 115. At the same time, the cover plate 13 has a second vent that penetrates the cover plate 13 so that the second vent is connected to the first receiving cavity 114. That is, heat is dissipated through both the first vent 14 and the second vent to accelerate the heat dissipation efficiency.

[0060] Of course, the stator module 10 also includes a circuit board, which is fixed in the cavity 11A of the stator base 11 and electrically connected to the circuit integration board 60 to supply power to the circuit integration board 60 and transmit signals. The circuit integration board 60 is electrically connected to the stator winding to realize the periodic excitation control of the stator winding. During the movement of the mover module 20, a large amount of heat will be generated. Therefore, the heat generated by the stator winding can also be dissipated through the first ventilation port 14 and the second ventilation port mentioned above.
