[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] To address the issues of large size and low integration in existing motor controllers due to their dispersed structure, such as... Figures 1 to 3 As shown, this application provides a motor controller module, which includes a housing 1, a filter assembly 2, a capacitor core assembly 3, a power module assembly 4, a three-phase plastic-coated assembly 5, and a drive board 6. The housing 1 serves as the overall structural carrier for mounting and fixing the various functional components, and has a heat dissipation channel 11 inside, located between a first side and a second side of the housing 1 that are opposite to each other. A receiving groove 12 is also formed on the first side of the housing 1 for centrally arranging the filter assembly 2 and the capacitor core assembly 3.

[0029] The filter assembly 2 is electrically connected to the capacitor core assembly 3. The filter assembly 2 is used to suppress electromagnetic interference and purify the input current to protect the controller's front-end circuit from external disturbances. The capacitor core assembly 3 is used to stabilize the DC bus voltage and suppress voltage fluctuations caused by sudden current changes, thereby providing a stable power input to the power module assembly 4. By placing the filter assembly 2 and the capacitor core assembly 3 together in the receiving slot 12, the structural space of the housing 1 is effectively utilized, improving the internal space utilization and integration level of the module.

[0030] The power module assembly 4 is located on the second side of the housing 1 and is electrically connected to the capacitor core assembly 3. It converts DC power to AC power by controlling the switching on and off of the internal power switching devices. The heat dissipation channel 11 not only dissipates heat from the power module assembly 4, but also provides coordinated heat dissipation for the filter assembly 2 and the capacitor core assembly 3 located on the first side. This achieves multi-area thermal management within a limited space, reduces the occupation of additional heat dissipation structures, and further improves the compactness of the module.

[0031] The three-phase plastic-coated assembly 5 is also located on the second side of the housing 1 and is electrically connected to the power module assembly 4, used to transmit the AC power output by the power module assembly 4 to the motor. The drive board 6 is also located on the second side and covers the power module assembly 4 and the three-phase plastic-coated assembly 5. The drive board 6 is electrically connected to the power module assembly 4 and is used to provide control signals to drive the operation of the power module assembly 4.

[0032] This application integrates components such as the filter assembly 2, capacitor core assembly 3, and power module assembly 4 into corresponding positions in the same housing 1, and achieves integrated heat dissipation with the help of the heat dissipation channel 11. This makes the motor controller module more compact in structure, simplifies the assembly process, and significantly reduces the overall volume, thereby effectively improving the product's spatial adaptability and integration while ensuring functional integrity.

[0033] like Figure 4 and Figure 5 As shown, in a specific embodiment of this application, the capacitor pack assembly 3 includes a capacitor pack 31, a positive busbar 32, and a negative busbar 33. The positive busbar 32 is electrically connected to the positive terminal of the capacitor pack 31, and at least a portion of it is configured to abut against the wall of the receiving groove 12 adjacent to the heat dissipation channel 11, so as to facilitate the more direct conduction of the heat generated by the capacitor pack 31 during operation to the heat dissipation channel 11 through the positive busbar 32, thereby improving the overall heat dissipation efficiency. The negative busbar 33 is electrically connected to the negative terminal of the capacitor pack 31. The capacitor pack 31 structurally encloses a placement space 34, and the pins on the positive busbar 32 and the negative busbar 33 for external electrical connection are all disposed within this placement space 34.

[0034] like Figure 4 and Figure 6 As shown, in a specific embodiment of this application, the filter component 2 is disposed within the placement space 34 formed by the capacitor core package 31. The filter component 2 includes a first magnetic ring 21, a filter plate 22, and a shield 23. The pins of the positive busbar 32 and the negative busbar 33 pass through the first magnetic ring 21 and are electrically connected to the filter plate 22. Four Y capacitors are arranged on the filter plate 22, which together constitute a passive filter circuit. The shield 23 covers the outside of the first magnetic ring 21 and the filter plate 22, physically isolating them from the capacitor core package 31. The shield 23 is grounded to the housing 1 by screws. This structure effectively avoids coupling interference between the busbar of the capacitor core package 31 and the busbar at the front end of the first magnetic ring 21, thereby ensuring that the electromagnetic compatibility (EMC) performance of the entire module meets the requirements. This not only improves the structural compactness between the capacitor core package component 3 and the filter component 2, but also helps to reduce the overall size.

[0035] like Figure 5 As shown, in one specific embodiment of this application, the capacitor core package 31 includes a first capacitor core package unit 311 and a second capacitor core package unit 312 that are mirror-symmetrically distributed with respect to the centerline of the housing 1, and a third capacitor core package unit 313 disposed between the first capacitor core package unit 311 and the second capacitor core package unit 312. The first capacitor core package unit 311, the third capacitor core package unit 313 and the second capacitor core package unit 312 can be arranged in a U-shape or H-shape in space, and together they enclose a space 34 for accommodating the pins on the positive busbar 32 and the negative busbar 33 that are electrically connected to the outside.

[0036] In one specific embodiment of this application, the motor controller module further includes a sealant filling the gaps between the housing 1, the filter assembly 2, and the capacitor core assembly 3. After curing, the sealant firmly bonds the housing 1, the filter assembly 2, and the capacitor core assembly 3 into a single structure, enhancing not only the structural stability and shock resistance of the components but also providing moisture and dust protection and improving heat dissipation pathways, thereby further enhancing the module's reliability under harsh operating conditions.

[0037] like Figure 7 and Figure 8As shown, in one specific embodiment of this application, the three-phase plastic-coated assembly 5 includes at least one three-phase plastic-coated unit. Specifically, when the three-phase plastic-coated assembly 5 has only one three-phase plastic-coated unit, it constitutes a single-drive three-phase plastic-coated assembly, which includes a U-phase copper busbar 51, a V-phase copper busbar 52, and a W-phase copper busbar 53. When the three-phase plastic-coated assembly 5 includes two three-phase plastic-coated units, it constitutes a dual-drive three-phase plastic-coated assembly, which specifically includes a first U-phase copper busbar 54, a first V-phase copper busbar 55, a first W-phase copper busbar 56, and a second U-phase copper busbar 57, a second V-phase copper busbar 58, and a second W-phase copper busbar 59. The above-mentioned single-drive three-phase plastic-coated assembly and dual-drive three-phase plastic-coated assembly can be electrically connected to the power module assembly 4 as replaceable components, thereby flexibly realizing the switching between single-channel or dual-channel AC output modes to adapt to different drive requirements.

[0038] like Figure 9 and Figure 10 As shown, in one specific embodiment of this application, the power module assembly 4 includes at least a first power module unit and a second power module unit.

[0039] The first power module unit consists of a first power module 41, a second power module 42, and a third power module 43; the second power module unit consists of a fourth power module 44, a fifth power module 45, and a sixth power module 46. In terms of layout, the first power module 41 and the fourth power module 44 are arranged opposite each other, the second power module 42 and the fifth power module 45 are arranged opposite each other, and the third power module 43 and the sixth power module 46 are arranged opposite each other, thus forming a symmetrical power device arrangement structure.

[0040] When the motor controller module is configured in single-output mode, a single-drive three-phase plastic-coated assembly is electrically connected to the power module assembly 4. In this connection, the first power module 41 and the fourth power module 44 are jointly connected to the U-phase copper busbar 51; the second power module 42 and the fifth power module 45 are jointly connected to the V-phase copper busbar 52; and the third power module 43 and the sixth power module 46 are jointly connected to the W-phase copper busbar 53, thereby realizing the parallel output of power devices to improve the single-drive capability.

[0041] When the motor controller module is configured in dual-output mode, a dual-drive three-phase plastic-coated assembly is used to electrically connect with the power module assembly 4. In this case, the first power module 41 is connected to the first U-phase copper busbar 54, the second power module 42 is connected to the first V-phase copper busbar 55, and the third power module 43 is connected to the first W-phase copper busbar 56, forming the first set of three-phase outputs. The fourth power module 44 is connected to the second U-phase copper busbar 57, the fifth power module 45 is connected to the second V-phase copper busbar 58, and the sixth power module 46 is connected to the second W-phase copper busbar 59, forming the second set of independent three-phase outputs to meet the application requirements of independent dual-motor drive.

[0042] Through the aforementioned alternative electrical connection methods, the power module component 4 can be flexibly adapted to different three-phase plastic-coated components 5, realizing the function switching between single-channel high-current output and dual-channel independent output, thereby enhancing the application versatility and flexibility of the motor controller module.

[0043] like Figure 7 and Figure 8 As shown, in a specific embodiment of this application, the three-phase plastic-coated assembly 5 further includes a plastic shell 510, a silicon steel sheet 511, and a second filter magnetic ring 512. The plastic shell 510 integrates the three-phase plastic-coated unit, the silicon steel sheet 511, and the second filter magnetic ring 512 into a compact, highly insulating integrated structure through a plastic coating process. Furthermore, the built-in silicon steel sheet 511 and the second filter magnetic ring 512 effectively suppress high-frequency noise, improve the output current quality, and enhance structural strength and electrical insulation reliability.

[0044] In one specific embodiment of this application, a Hall sensor is integrated on the drive board 6. This Hall sensor cooperates with the silicon steel sheet 511 inside the three-phase plastic-coated assembly 5 to detect the output current flowing through the three-phase plastic-coated assembly 5 in a non-contact manner, thereby realizing real-time monitoring and feedback of the motor phase current and providing the necessary current parameters for the precise control of the power module assembly 4.

[0045] like Figures 11 to 13 As shown, in a specific embodiment of this application, the heat dissipation channel 11 includes an inlet 111 and an outlet 112 disposed on the housing 1, and several branch channels connected in parallel between the inlet 111 and the outlet 112. Each branch channel is composed of a first cavity 113, a second cavity 114, and a third cavity 115 connected in sequence. The first cavity 113 is directly connected to the inlet 111, and the third cavity 115 is connected to the outlet 112. In terms of spatial layout, the first cavity 113 and the third cavity 115 are both disposed close to the first side of the housing 1, so that they can effectively cool the filter component 2 and the capacitor core assembly 3 disposed on that side; the second cavity 114 is disposed close to the second side of the housing 1, so as to directly dissipate heat from the power module assembly 4 located on that side.

[0046] like Figures 11 to 13As shown, in one specific embodiment of this application, the second cavity 114 constituting the heat dissipation channel 11 has an opening on the second side facing the housing 1. The power module assembly 4 is installed at this opening and sealed, so that the power module assembly 4 and the second cavity 114 together form a complete cooling channel. A heat dissipation fin is provided on the side of the power module assembly 4 facing the interior of the second cavity 114. After the power module assembly 4 is installed, the heat dissipation fin extends into the coolant channel of the second cavity 114, thereby increasing the heat exchange area between the power module assembly 4 and the coolant. This allows for efficient transfer of the heat generated during power module operation to the flowing coolant, improving the heat dissipation efficiency of the core heat-generating components.

[0047] This application also provides a motor controller that includes the motor controller module described in detail in any of the foregoing embodiments. Since this motor controller inherits all the technical features of the aforementioned motor controller modules, it also possesses the advantages of compact structure, high integration, excellent heat dissipation performance, and flexible configuration of output modes.

[0048] This application also provides an electric motor that includes the motor controller described in any of the foregoing embodiments. Because the motor uses the aforementioned motor controller, it also possesses the advantages of a compact structure, reliable operation, and strong adaptability brought about by the highly integrated, efficient heat dissipation, and flexible output modes of the controller.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
