Description

Technical Field

[0001] This utility model belongs to the field of motor parts technology, and relates to a motor, and particularly to a stator and rotor of a motor with stacked riveting. Background Technology

[0002] The stator and rotor of the motor are formed by the fit between the rivet points and rivet grooves on the laminations to form the lamination core.

[0003] Currently, the heat generated by the stacked stator and rotor of the motor during operation is not easily dissipated to the outside, which affects the service life of the entire machine. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a motor stator and rotor with good heat dissipation.

[0005] The objective of this utility model can be achieved through the following technical solution: A stator and rotor of a motor, comprising a stator core and a rotor core, characterized in that the rotor core is formed by stacking and riveting multiple rotor laminations, each rotor lamination having multiple slots, a heat dissipation end cap installed at one end of the rotor core, the heat dissipation end cap having multiple heat dissipation rods positioned and inserted into the slots, the heat dissipation rods being coated with thermally conductive potting compound, the ends of the heat dissipation rods extending out of the rotor core and being fitted with positioning end caps, the heat dissipation rods and the heat dissipation end cap being integrally formed, the positioning end cap being provided with locking nuts threaded to the outer ends of the heat dissipation rods, the heat dissipation end cap having a shaft hole disc, a heat-conducting strip between the shaft hole disc and the heat dissipation rods, a gap between the heat-conducting strip and the heat dissipation end cap, and an open heat-conducting groove on the heat-conducting strip.

[0006] In the aforementioned stacked stator and rotor of an electric motor, the heat-conducting strip has a curved structure.

[0007] Compared with existing technologies, the stator and rotor of this motor have the advantage of better heat dissipation. Attached Figure Description

[0008] Figure 1 This is a 3D view of the stator and rotor of this motor.

[0009] Figure 2 This is a 3D view of the rotor core.

[0010] In the diagram, 1 is the stator core; 2 is the rotor core; 3 is the rotor lamination; 4 is the heat dissipation end cover; 5 is the heat dissipation rod; 6 is the positioning end cover; 7 is the shaft hole plate; 8 is the heat conduction strip; and 9 is the heat conduction groove. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, this motor has a stator and rotor assembly, including a stator core 1 and a rotor core 2. The rotor core 2 is formed by stacking and riveting multiple rotor laminations 3. Each rotor lamination 3 has multiple slots. A heat dissipation end cover 4 is installed at one end of the rotor core 2. The heat dissipation end cover 4 has multiple heat dissipation rods 5 that are positioned and inserted into the slots. The heat dissipation rods 5 are coated with thermally conductive potting compound. The ends of the heat dissipation rods 5 protrude from the rotor core 2 and are fitted with positioning end covers 6. The heat dissipation rods 5 and the heat dissipation end cover 4 are integrally formed. The positioning end cover 6 is provided with a locking nut that is threaded to the outer end of the heat dissipation rod 5. The rotor core 2 has a shaft hole disk 7, and a heat-conducting strip 8 is between the shaft hole disk 7 and the heat dissipation rod 5. There is a gap between the heat-conducting strip 8 and the heat dissipation end cover 4. The heat-conducting strip 8 has an open heat-conducting groove 9. When the rotor core 2 rotates at high speed, heat is generated. The heat inside the core is guided and transferred to the outside through multiple heat dissipation rods 5 and the heat-conducting potting compound on the heat dissipation rods 5. The heat is then dissipated through multiple heat-conducting strips 8 and heat-conducting grooves 9 on the heat dissipation end cover 4, achieving efficient heat dissipation. When the multiple heat-conducting strips 8 rotate, they can act as impellers to provide a certain airflow speed, improving the heat dissipation effect.

[0013] Preferably, the heat-conducting strip 8 has a curved structure.

[0014] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0015] Although this document frequently uses terms such as stator core 1, rotor core 2, rotor lamination 3, heat dissipation end cover 4, heat dissipation rod 5, positioning end cover 6, shaft hole plate 7, heat-conducting strip 8, and heat-conducting groove 9, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
