The integrated structure of the stator core 61 and the rubber-coated frame 62 simplifies the manufacturing process and installation steps. Through injection molding, the assembly process and the number of parts can be reduced, and the production efficiency can be improved.

[0070] In the above embodiment, a rubber-coated liner 621 is provided on the inner side of the rubber-coated skeleton 62, and the rubber-coated liner 621 is used to cover the inside of the stator core 61 and fix it on the base 1. The rubber-coated liner 621 is located on the inner side of the rubber-coated skeleton 62, and is used to cover and fix the inside of the stator core 61. By setting the rubber-coated liner 621, it can be ensured that the internal structure of the stator core 61 is stable and tightly connected to the base 1. The rubber-coated liner 621 serves as an internal protective layer of the stator core 61, which can prevent the stator core 61 from direct contact with the external environment and reduce its influence by external substances and damage. At the same time, the rubber-coated liner 621 can also isolate the friction and vibration between the stator core 61 and the base 1, thereby improving the stability of the overall structure.

[0071] See also Fig.16As shown, the outer side of the motor mounting portion 11 is provided with a direction positioning groove 112, and the stator core 61 is provided with a positioning groove 611, and the positioning groove 611 cooperates with the direction positioning groove 112 to form a positioning hole, and a positioning pin 612 is provided on the positioning hole, and the positioning pin 612 is used for positioning the stator core 61 after the stator core 61 cooperates with the motor mounting portion 11. In this embodiment, the positioning hole is formed by the cooperation of the direction positioning groove 112 and the positioning groove 611, and the positioning pin 612 is provided on the positioning hole, so that the accurate positioning between the stator core 61 and the motor mounting portion is achieved. In this way, the correct alignment of the stator core 61 and the motor mounting portion can be ensured, and the normal operation and performance of the motor can be ensured. The design of the positioning groove 611 and the positioning hole can provide a stable fixing effect. The shape of the positioning groove 611 and the cooperation of the direction positioning groove 112 ensure the firm connection between the stator core 61 and the motor mounting portion, reduce looseness and vibration, and improve the stability and reliability of the motor.

[0072] The outer circumference of the stator core 61 is evenly distributed with a plurality of tooth blocks 613, and a tooth groove is provided between two adjacent tooth blocks 613, and a stopper 614 is provided at the outer end of the tooth block 613; the rubber-coated frame 62 covers the tooth block 613 and the stopper 614 by injection molding; and a coil is wound around the outside of the tooth block 613. In this embodiment, the design of the positioning groove 611, the direction positioning groove 112, the positioning hole and the positioning pin 612 can realize the rapid installation of the motor assembly. The cooperation of the positioning hole and the positioning pin 612 can conveniently align and fix the stator core 61 with the motor mounting part, simplifying the installation process and improving production efficiency.

[0073] The rotor assembly 7 includes a rotor frame 71 and a magnetic tile 72 mounted on the rotor frame 71, and one side of the magnetic tile 72 is arranged opposite to the tooth block 613. In this embodiment, a magnetic field can be generated in the rotor assembly 7 by installing the magnetic tile 72 on the rotor frame 71. The magnetic tile 72 is usually made of magnetic material, and when current passes through the magnetic tile 72, a magnetic field is generated, thereby realizing the magnetodynamic effect of the motor. One side of the magnetic tile 72 is arranged opposite to the tooth block 613, and the tooth block 613 is a part of the stator assembly 6. The magnetic coupling between the rotor and the stator is achieved by docking the magnetic tile 72 with the tooth block 613. When current passes through the magnetic tile 72 of the rotor, it interacts with the tooth block 613 of the stator to generate rotational force and movement. By adjusting the arrangement of the magnetic tile 72 and the properties of the magnetic material, the strength and direction of the magnetic field can be controlled. This helps to achieve the control and adjustment of performance parameters such as the speed, torque and efficiency of the motor.
