[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 2 and Figure 4The utility model provides an embodiment: a motor stator-rotor core, including a stator sheet 1 and a rotor sheet 2, wherein a plurality of stator sheets 1 are stacked to form a stator core body, and a plurality of rotor sheets 2 are stacked to form a rotor core body.

[0024] Specifically, a stator chip and a rotor chip can be formed by stacking a plurality of stator sheets 1 and a plurality of rotor sheets 2, and the stator chip and the rotor chip are the main body of the stator and rotor core of the motor.

[0025] Reference Figure 1 and Figure 2 A plurality of through holes 11 are opened inside the stator sheet 1, and the plurality of through holes 11 surround the outside of the stator sheet 1. A marking groove 12 is opened at the left end of the stator sheet 1, and the marking groove 12 is arc-shaped. A plurality of rivet grooves 13 are opened inside the stator sheet 1, and the plurality of rivet grooves 13 surround the outer surface of the stator sheet 1.

[0026] Specifically, through the through hole 11, air can circulate better, thereby helping to dissipate heat, reducing the heat generated when the motor is running, and reducing the total weight of the stator sheet 1. The marking groove 12 can be used as an alignment mark during installation and assembly to ensure that multiple stator sheets 1 can be accurately aligned during the assembly process. The rivet groove 13 is used to firmly rivet multiple stator sheets 1 together to form a whole, thereby helping to maintain the stability and rigidity of the stator sheet 1.

[0027] Reference Figure 3 and Figure 4 A center hole 21 is provided inside the rotor sheet 2, and the outside of the protrusion 23 is fixedly connected to the inner wall of the center hole 21. A plurality of arc grooves 22 are provided inside the rotor sheet 2, and the arc grooves 22 surround the outside of the rotor sheet 2. A protrusion 23 is provided inside the rotor sheet 2. A plurality of winding holes 24 are provided inside the rotor sheet 2, and the winding holes 24 surround the outside of the rotor sheet 2. The winding holes 24 are provided with a beveled edge on the inner edge, and every two winding holes 24 form a V shape. A plurality of rivet grooves 25 are provided inside the rotor sheet 2, and the rivet grooves 25 surround the outer surface of the rotor sheet 2. The plurality of rivet grooves 25 are divided into inner and outer sides. A plurality of circular grooves 26 are provided inside the rotor sheet 2, and the circular grooves 26 surround the outside of the rotor sheet 2.

[0028] Specifically, the center hole 21 is used to connect with the shaft of the motor so that the rotor sheet 2 can be fixed on the shaft and rotate with the shaft. The arc groove 22 helps to improve the internal airflow and promote the cooling effect, thereby reducing overheating during the operation of the motor. The winding hole 24 is used to arrange the winding coil of the motor. The bevel design helps to guide the correct placement of the coil and reduce friction loss during winding. The rivet groove 25 is used to firmly rivet multiple rotor sheets 2 into a whole to improve the stability of the structure. The circular groove 26 is designed to facilitate air flow, enhance heat dissipation, and help control the temperature of the motor. The bump 23 is used to strengthen the structural strength of the rotor sheet 2, prevent deformation, and ensure the stability of the rotor sheet 2 during high-speed rotation.

[0029] Working principle: The multiple through holes 11 opened inside the stator sheet 1 are used to arrange the winding coils of the stator. These through holes 11 surround the outside of the stator sheet 1, and can evenly distribute the winding coils, so as to generate a uniform and strong rotating magnetic field when power is turned on. Through riveting through the riveting groove 13, multiple stator sheets 1 can be tightly combined, thereby improving the structural strength, reducing vibration and noise, and improving the running stability of the motor;

[0030] The rotor sheet 2 is firmly mounted on the shaft through the center hole 21 and rotates with the shaft. When the motor is powered on, the current passes through the stator winding to generate a rotating magnetic field. This magnetic field interacts with the magnetic field in the rotor, so that the shaft drives the rotor sheet 2 to rotate. The arc groove 22 and the circular groove 26 not only reduce the weight of the rotor, but also form an internal air flow channel to ensure effective heat dissipation during operation and prevent overheating. Multiple rotor sheets 2 are firmly connected by the riveting groove 25, and the protrusion 23 further enhances the structural strength of the rotor sheet 2 to ensure that it does not deform during high-speed rotation.
