Multiple sets of positioning holes 4 are opened on the inner wall of the housing 1 between the two sets of MOS transistors 5. An aluminum pressure strip body 3 is snapped between each set of MOS transistors 5 and the main board 2. The aluminum pressure strip body 3 is stepped. Multiple positioning bolts 6 are rotatably inserted in the inner wall of each aluminum pressure strip body 3. The positioning bolts 6 located inside the positioning holes 4 are threadedly connected to the inner wall of the housing 1.
[0028] A motor power terminal 12 is installed on the outer wall of the housing 1. The motor power terminal 12 extends into the interior of the housing 1. A function line output coil 13 is installed in the inner wall of the housing 1 below the motor power terminal 12. A fault display digital tube 14 is installed in the inner wall of the housing 1 on one side of the function line output coil 13.
[0029] In the technical solution of this utility model, the MOS tube 5 and the motherboard 2 can be fixed by the stepped aluminum pressure strip body 3 and the positioning bolt 6. The aluminum pressure strip body 3 is made of aluminum, which has excellent thermal conductivity, facilitates heat dissipation, and is easy to install without easily damaging the motherboard 2.
[0030] In addition, the housing 1 can fix the motor power terminal 12, the functional line output coil 13, and the fault display digital tube 14.
[0031] In the technical solution of this utility model, such as Figures 2-4As shown, multiple sets of mounting posts 8 are fixedly connected to the inner wall of the housing 1. A storage groove 7 is provided on the lower side of the housing 1 around the multiple sets of mounting posts 8. The housing 1 can fix the mounting posts 8. A base plate 9 is placed on the inner wall of the housing 1 inside the storage groove 7. Multiple sets of mounting bolts 10 are rotatably passed through the inner wall of the base plate 9. The mounting bolts 10 inside the mounting posts 8 are threadedly connected to the mounting posts 8. The storage groove 7 can store the base plate 9, and the mounting bolts 10 cooperate with the mounting posts 8 to fix the base plate 9, thereby facilitating the closing of the base plate 9 onto the housing 1.
[0032] In the technical solution of this utility model, such as Figure 1 and Figure 4 As shown, mounting holes 11 are provided on the upper side of the corners of the housing 1, which facilitates the installation of the housing 1 on the outside of other devices.
[0033] When in use, first, install the two sets of MOSFETs 5 on the inner top wall of the housing 1 to ensure that their positional relationship is correct, and then install the motherboard 2 on the inner top wall of the housing 1 between the two sets of MOSFETs 5 to ensure that the connection between the motherboard 2 and the MOSFETs 5 is correct.
[0034] The stepped aluminum pressure strip body 3 is snapped between each group of MOS transistors 5 and the main board 2 to ensure that they fit tightly. Multiple positioning bolts 6 are rotated through the inner wall of the aluminum pressure strip body 3 and these positioning bolts 6 are threaded to the inner wall of the housing 1 to fix the aluminum pressure strip body 3.
[0035] Place the base plate 9 inside the storage groove 7 of the housing 1, rotate and pass multiple sets of mounting bolts 10 through the inner wall of the base plate 9, and thread these mounting bolts 10 to the mounting post 8 inside the housing 1 to fix the base plate 9.

[0037] The aluminum pressure strip body 3 not only serves to fix the MOSFET 5 and the motherboard 2, but also uses its excellent thermal conductivity to help dissipate heat, effectively reducing the operating temperature of the motor controller and extending its service life.
[0038] The stepped aluminum pressure strip body 3 and the positioning bolts 6 work together to make the installation process more convenient and efficient, reducing installation time and cost. The base plate 9 is connected to the mounting column 8 by the mounting bolts 10, which enhances the overall structural stability of the housing 1 and ensures the reliability of the motor controller in various working environments.
[0039] The fault display digital tube 14 can display the fault information of the motor controller in real time, which makes it easier for users to quickly locate and solve problems, improving maintenance efficiency and safety.
[0040] The setting of the function line output coil 13 makes the function line neater and more orderly, reduces the risk of failure caused by messy wiring, and also facilitates subsequent maintenance and repair work.
[0041] In summary, the motor controller with aluminum pressure strip in this application demonstrates significant advantages in terms of heat dissipation, ease of installation, structural stability, fault display function, and function line management.
