[0002] An electric motor is an electromagnetic device that converts electrical energy into mechanical energy. It is widely used in industries, transportation, home appliances, aerospace and other fields, and is one of the core power sources of modern industry and daily life.

[0003] Currently, the outer wall of the motor is equipped with multiple sets of ports, usually four, to facilitate the installation and connection of connecting wires. However, when there are more ports, it is inconvenient to install and increases the number of sealing points on the casing. Utility Model Content

[0004] The purpose of this application is to provide a single-core double parallel wire for motors, which solves the problem mentioned in the background art that the outer wall of the motor is provided with multiple sets of ports, usually four, to facilitate the installation and connection of connecting wires. However, when the number of ports is too large, it is inconvenient to install and increases the number of sealing points on the casing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a single-core double parallel wire for a motor, including a motor body. The motor body includes a middle cylinder, and at least one set of terminals is fixedly installed in the inner wall of the middle cylinder. At least one connecting wire is fixedly installed inside each set of terminals.

[0007] By adopting the above technical solution, at least one set of terminals is fixedly installed on the inner wall of the middle cylinder, and at least one connecting wire is fixed inside each set of terminals. This design allows the connecting wires to be concentrated in specific terminals. Compared with the traditional method of setting multiple sets of ports on the outer wall of the motor to connect and install the connecting wires, the number of ports is reduced. This not only avoids the problem of inconvenient installation due to too many ports, but also reduces the number of sealing points on the casing, effectively improving the convenience of motor installation and the reliability of casing sealing.

[0008] Optionally, a front cover is provided at one end of the middle cylinder.

[0009] By adopting the above technical solution, the front cover can effectively shield the front end of the middle tube.

[0010] Optionally, a rear cover is provided on the side of the middle cylinder away from the front cover.

[0011] By adopting the above technical solution, the rear cover can effectively shield the rear end of the middle tube.

[0012] Optionally, a stator is embedded in the inner wall of the middle cylinder, and a rotor is embedded in the inner wall of the stator.

[0013] By adopting the above technical solution, the middle cylinder can be used to store and install the stator and rotor.

[0014] Optionally, a central shaft is embedded in the inner wall of the rotor.

[0015] By adopting the above technical solution, the central shaft can be driven to rotate through the coordination of the stator and the rotor.

[0016] Optionally, bearings are embedded in the central inner walls of the front cover and the rear cover, and the central shaft is embedded through two bearings. A set of fan blades is installed on the outer wall of the central shaft located inside the rear cover.

[0017] By adopting the above technical solution, the front cover and the rear cover can fix the bearing, and the bearing can facilitate the rotation of the central shaft. When the central shaft rotates, it can drive the fan blades to rotate, which facilitates heat dissipation of the motor body.

[0018] Optionally, a set of heat dissipation holes are provided on the outer wall of the rear cover, and mounting holes are provided on the outer wall of the corners of the rear cover around the heat dissipation holes, and the mounting holes penetrate the middle tube and the front cover.

[0019] By adopting the above technical solution, heat can be easily dissipated through the heat dissipation holes, and mounting holes are provided in the inner walls of the front cover, middle cylinder and rear cover respectively, so that external equipment bolts and nuts can be used to fix the front cover, middle cylinder and rear cover.

[0020] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0021] The technical solution of this application fixes at least one set of terminals on the inner wall of the middle cylinder, and fixes at least one connecting wire inside each set of terminals. This design allows the connecting wires to be concentrated in specific terminals. Compared with the traditional method of setting multiple sets of ports on the outer wall of the motor to connect and install the connecting wires, the number of ports is reduced. This not only avoids the problem of inconvenient installation due to too many ports, but also reduces the number of sealing points on the casing, effectively improving the convenience of motor installation and the reliability of casing sealing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-3 This application provides a technical solution: a single-core double parallel wire for a motor, including a motor body 1, the motor body 1 including a middle cylinder 2, at least one set of terminals 3 are fixedly installed in the inner wall of the middle cylinder 2, and at least one connecting wire 4 is fixedly installed inside each set of terminals 3;

[0029] In the technical solution of this application, at least one set of terminals 3 is fixedly installed on the inner wall of the middle cylinder 2, and at least one connecting wire 4 is fixed inside each set of terminals 3. This design allows the connecting wires 4 to be concentrated in specific terminals 3. Compared with the traditional method of setting multiple sets of ports on the outer wall of the motor to connect and install the connecting wires 4, the number of ports is reduced. This not only avoids the problem of inconvenient installation due to too many ports, but also reduces the number of sealing points of the housing, effectively improving the convenience of motor installation and the reliability of housing sealing.

[0030] In the technical solution of this application, such as Figure 2 As shown, a stator 7 is embedded in the inner wall of the middle cylinder 2, and a rotor 8 is embedded in the inner wall of the stator 7. The middle cylinder 2 can store and install the stator 7 and the rotor 8. A central shaft 9 is embedded in the inner wall of the rotor 8. The central shaft 9 can be driven to rotate by the rotation of the stator 7 and the rotor 8.

[0031] In the technical solution of this application, such as Figure 1 and Figure 2 As shown, a front cover 6 is provided at one end of the middle tube 2, which can cover the front end of the middle tube 2. A rear cover 5 is provided on the side of the middle tube 2 away from the front cover 6, which can cover the rear end of the middle tube 2.

[0032] In the technical solution of this application, such as Figure 2 and Figure 3 As shown, bearings 10 are embedded in the inner walls of the front cover 6 and the rear cover 5, respectively. The central shaft 9 is embedded through two bearings 10. A set of fan blades 11 is installed on the outer wall of the central shaft 9 inside the rear cover 5. The bearings 10 can be fixed by the front cover 6 and the rear cover 5. The bearings 10 facilitate the rotation of the central shaft 9, and the rotation of the central shaft 9 can drive the fan blades 11 to rotate, which facilitates the heat dissipation of the motor body 1. A set of heat dissipation holes 12 are opened on the outer wall of the rear cover 5. Mounting holes 13 are opened on the outer wall of the corners of the rear cover 5 around the heat dissipation holes 12. The mounting holes 13 penetrate the middle cylinder 2 and the front cover 6. The heat dissipation holes 12 facilitate the dissipation of heat. The mounting holes 13 are respectively provided in the inner walls of the front cover 6, the middle cylinder 2 and the rear cover 5, so that the bolts and nuts of the external equipment can be used to fix the front cover 6, the middle cylinder 2 and the rear cover 5.

[0033] In use, the stator 7 on the inner wall of the middle cylinder 2 generates a magnetic field when energized, which interacts with the rotor 8 embedded in the inner wall of the stator 7. Under the action of electromagnetic induction, the rotor 8 is driven to rotate. The rotor 8 drives the central shaft 9 embedded in the inner wall to rotate. The central shaft 9 passes through the bearing 10 in the center of the front cover 6 and the rear cover 5. The bearing 10 ensures the stable rotation of the central shaft 9. When the central shaft 9 rotates, it drives the fan blade 11 installed inside the rear cover 5 to rotate. The fan blade 11 accelerates the air flow. Together with the heat dissipation holes 12 on the outer wall of the rear cover 5, the heat inside the motor is dissipated. At the same time, the wiring terminals 3 on the inner wall of the middle cylinder 2 centrally fix the connecting wires 4, reducing the installation inconvenience and sealing problems caused by the traditional multi-port connection method on the outer wall of the motor, and ensuring the stable and efficient operation of the motor.
