Description

Technical Field

[0001] The utility model belongs to the field of motor accessories and relates to a stator and rotor, in particular to a fast volatilization heat dissipation stator and rotor. Background Art

[0002] The stator and rotor are important components of the motor. The stator and rotor will generate heat when they rotate. The existing heat dissipation structure applied to the stator and rotor usually adopts the method of adding impellers to dissipate the heat outside the stator and rotor. The internal heat of the stator and rotor during its movement still cannot be dissipated. The stator and rotor with high working intensity still cannot quickly dissipate the heat inside. The heat dissipation effect is poor and seriously affects the service life and working efficiency of the stator and rotor. At the same time, with the continuous improvement and reduction of the stator and rotor structure, a very small number of stators and rotors can no longer quickly dissipate the heat by adding impellers.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figure 1 , Figure 2As shown, the present fast evaporation heat dissipation stator and rotor include a stator core 1 and a rotor assembly wound with copper wire, the stator core 1 and the rotor assembly are connected by a transmission shaft, the transmission shaft is arranged through the stator core 1 and the rotor assembly, and drives the rotor assembly to rotate, the rotor assembly is formed by splicing two rotor parts 2 arranged in a relative structure, the two rotor parts 2 are respectively located at the two ends of the stator core 1, and are driven to rotate by the transmission shaft, the rotor part 2 is axially extended with a plurality of extensions 3 for guiding splicing, the two rotor parts 2 are arranged in a corresponding structure, and the extensions 3 of the two rotor parts 2 are arranged in an interval and staggered structure, and a heat dissipation gap 4 for fast evaporation heat dissipation is provided between the two connected extensions 3, and a heat dissipation structure for fast air cooling of the stator core 1 is provided at the center of the rotor part 2, the heat dissipation structure includes a pillow block 5 for easy penetration and driving of the transmission shaft and a plurality of blade ribs 6 for fast evaporation, and the blade rib 6 and the pillow block 5 are an integrally formed structure arranged on the rotor part 2.

[0021] The structure is simple in design, and the rotor component 2 splicing structure and the heat dissipation mechanism structure are used to effectively realize the rapid circulation of internal air to improve the heat dissipation effect. At the same time, the principle of the stator being stationary while the rotor rotates is used, and the heat dissipation mechanism and the heat dissipation through hole 9 are used to quickly dissipate the internal and external temperatures when the stator and rotor are working.

[0022] To elaborate further, in order to realize the impeller-type heat dissipation structure of the rotor component 2, the blade ribs 6 are arranged in sequence along the outer wall of the pillow block 5 in a circumferential direction and are arranged in a blade-type spiral structure. The central part of the rotor component 2 is provided with an axial hole 7 in which the pillow block 5 and the blade ribs 6 are installed. The pillow block 5 is connected to the axial hole 7 through a plurality of blade ribs 6 and is an integrally formed structure. The above structure realizes an air cooling effect on the rotor component 2 itself, reduces the need to add an impeller for rapid heat dissipation, and meets the heat dissipation function of individual stator and rotor structures that cannot be equipped with impellers.

[0023] To further elaborate, in order to improve the rapid heat dissipation effect inside the stator core 1 and prevent the internal heat from being unable to volatilize, the extension part 3 on the rotor part 2 is provided with a through hole 8 for improving the internal heat dissipation efficiency, and the stator core 1 is provided with a heat dissipation through hole 9 for improving the internal heat dissipation. The number of the heat dissipation through holes 9 is 4, and they are arranged in sequence in a circumferential direction along the central axis of the stator core 1.

A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0025] Although the terms such as stator core 1, rotor member 2, extension 3, heat dissipation gap 4, pillow block 5, blade rib 6, shaft hole 7, through hole 8, heat dissipation through hole 9 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
