Description

Technical Field

[0001] The utility model belongs to the field of stators and rotors, and relates to a stator and rotor, in particular to a stator and rotor of a motor. Background Technique

[0002] As the name implies, the stator is the stationary part in a motor or pump body. The rotatable cylindrical component arranged inside this object is called the rotor. After connecting to the power supply, electromagnetic induction is generated between the two through coils and magnets, and then the connected shaft body and external objects are driven to rotate. Most of the previous stator and rotor structures rely on fans for external heat dissipation, and the heat dissipation effect is not ideal. In the case of high-intensity work of a water pump motor, the internal heat cannot be volatilized and dissipated in time, resulting in heat accumulation, which seriously affects the service life and efficiency of the stator and rotor. Summary of the Invention

[0003] The purpose of the utility model is to provide a stator and rotor of a motor with high heat dissipation to solve the above problems in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A stator and rotor of a motor, including a stationary stator part, a rotatable rotor part and a shaft body. The shaft body is connected through the center of the rotor part. Both ends of the shaft body are provided with bearing assemblies. It is characterized in that there is a gap between the rotor part and the stator part;

[0005] The central axes of the rotor part, the stator part and the shaft body are the same axis;

[0006] The rotor part includes a rotor inner cylinder provided with a hollow structure for the shaft body to penetrate, a rotor outer cylinder arranged concentrically with the rotor inner cylinder, and several connecting pieces for connection;

[0007] The rotor inner cylinder is located inside the rotor outer cylinder, and there is a connection gap between the two;

[0008] Several of the connecting pieces are located in the connection gap and are used to connect the rotor inner cylinder and the rotor outer cylinder;

[0009] Several of the connecting pieces are sequentially arranged in the connection gap in a spiral stepped structure.

[0010] In the above stator and rotor of a motor, the connecting piece is arranged in a fan-shaped plate structure, and the rotor inner cylinder, the rotor outer cylinder and the connecting piece are integrally formed.

[0011] In the above stator and rotor of a motor, the stator part, the rotor part and the shaft body are arranged coaxially and are installed from outside to inside in sequence.

[0012] In the above-mentioned motor stator and rotor, the shaft body penetrates and connects to the inner cylinder of the rotor, and the rotation of the rotor part drives the shaft body to rotate.

[0013] Compared with the prior art, the structure of this motor stator and rotor is simply designed. By utilizing the characteristics that the stator part is fixed and the rotor part rotates, the internal structure of the rotor part is improved. Through the structural cooperation of the inner rotor cylinder, the outer rotor cylinder and the connecting parts, during the rotation of the rotor part, due to the spiral stepped structure design of several connecting parts, the air circulation speed inside can be increased, thereby achieving the internal self-cooling effect.

[0018] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0019] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the stator and rotor of this motor include a stationary stator part 1, a rotatable rotor part 2, and a shaft body 3. The shaft body 3 is connected through the center of the rotor part 2, and bearing assemblies 4 are provided at both ends of the shaft body 3. There is a gap between the rotor part 2 and the stator part 1. The central axes of the rotor part 2, the stator part 1, and the shaft body 3 are the same axis. The rotor part 2 includes a rotor inner cylinder 5 provided with a hollow structure for the shaft body 3 to penetrate, a rotor outer cylinder 6 arranged concentrically with the rotor inner cylinder 5, and several connecting pieces 8 for connection. The rotor inner cylinder 5 is located inside the rotor outer cylinder 6, and there is a connection gap 7 between them. Several connecting pieces 8 are located in the connection gap 7 and are used to connect the rotor inner cylinder 5 and the rotor outer cylinder 6. Several connecting pieces 8 are arranged in a spiral stepped structure in the connection gap 7 in sequence. The structural design is simple. By taking advantage of the characteristics that the stator part 1 is stationary and the rotor part 2 rotates, the internal structure of the rotor part 2 is improved. Through the structural cooperation of the rotor inner cylinder 5, the rotor outer cylinder 6, and the connecting pieces 8, during the rotation of the rotor part 2, due to the spiral stepped structure design of several connecting pieces 8, the air circulation speed inside can be increased, thus achieving the internal self-cooling effect.

[0020] To elaborate further, in order to improve the self-cooling effect of the rotor part 2 during the rotation process, the connecting piece 8 is arranged in a fan-shaped plate structure. The rotor inner cylinder 5, the rotor outer cylinder 6, and the connecting piece 8 are integrally formed. The stator part 1, the rotor part 2, and the shaft body 3 are arranged coaxially and are installed from outside to inside in sequence. The shaft body 3 is connected through the rotor inner cylinder 5, and the rotation of the shaft body 3 is driven by the rotation of the rotor part 2.

[0021] The above structure effectively utilizes the design of the connecting piece 8 in a fan-shaped plate structure and in a spiral stepped structure, which can effectively achieve rapid air circulation during rotation, thus realizing the self-cooling effect.

Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0023] Although terms such as the stator part 1, the rotor part 2, the shaft body 3, the bearing assembly 4, the rotor inner cylinder 5, the rotor outer cylinder 6, the connection gap 7, and the connecting piece 8 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 present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
