Description

Technical Field

[0001] The utility model relates to the field of axial flux motors, and particularly to a rotor silicon steel sheet structure of a novel axial flux motor. Background Technique

[0002] The axial flux motor is a special type of motor whose working principle is based on the transfer of magnetic flux in the axial direction. Compared with traditional rotating motors, the magnetic field and current direction of the axial flux motor are parallel to the axis rather than perpendicular to the axis. This design can provide some advantages, such as higher power density and higher efficiency. The axial flux motor is usually used in some special application scenarios, such as aerospace, ships, wind power generation, etc. The rotor of the axial flux motor is an important part of it. Different from traditional rotating motors, the rotor design of the axial flux motor is more complex because it needs to ensure the transfer of magnetic flux in the axial direction. Generally, the rotor of the axial flux motor is composed of multiple magnetic materials, and these materials are arranged in the axial direction so as to generate a magnetic field when current passes through, thereby driving the motor to rotate.

[0003] The rotor of the axial flux motor is mostly made of silicon steel sheet material, which has excellent magnetic conductivity, but there are still some problems: poor heat dissipation performance, resulting in the stability, reliability or performance of the rotor being affected; Therefore, in view of the above current situation, there is an urgent need to develop a rotor silicon steel sheet structure of a novel axial flux motor to overcome the deficiencies in current practical applications and meet the current needs. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rotor silicon steel sheet structure of a novel axial flux motor to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rotor silicon steel sheet structure of a novel axial flux motor includes a silicon steel sheet body and inserts. Four inserts are distributed equidistantly in a ring on the side wall of the silicon steel sheet body and are integrally formed with the silicon steel sheet body. A winding groove is formed between two adjacent inserts and the silicon steel sheet body;

[0007] One side of the insert is provided with a wind groove, and a number of horizontally penetrating heat dissipation air ducts are arranged inside the insert.

[0008] As a further scheme of the utility model: a shaft hole is arranged at the central position of the silicon steel sheet body, and the arranged shaft hole is used for connecting with a rotating shaft.

[0009] As a further solution of the present utility model: Both ends of the heat dissipation air duct form an air inlet and an air outlet. The air inlet is located inside the air groove. During the rotation of the rotor, air can be promoted to flow into the heat dissipation air duct through the air groove, thereby dissipating heat from the rotor.

[0010] As a further solution of the present utility model: A plurality of heat dissipation air ducts are longitudinally and equidistantly distributed. The through direction of a single heat dissipation air duct is horizontal. By providing the heat dissipation air ducts, the heat dissipation effect can be improved.

[0011] As a further solution of the present utility model: The edge of the plug-in is arc-shaped. The distance from one end of the plug-in adjacent to the air groove to the axis is farther than the distance from the other end to the axis. Therefore, when the rotor rotates, air can be promoted to concentrate at the air groove.

[0012] Beneficial effects: For the rotor silicon steel sheet structure of this new type of axial flux motor, by providing an air groove and heat dissipation air ducts inside the plug-in to promote air to flow through the plug-in, this structural design can improve the heat dissipation performance of the rotor silicon steel sheet structure. At the same time, one side of the plug-in adjacent to the air groove is more convex than the other side. Therefore, when the rotor rotates, air can be promoted to concentrate at the air groove position, thereby improving the fluidity of the heat dissipation air duct and achieving a more efficient heat dissipation performance.

[0017] Embodiment

[0018] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a rotor silicon steel sheet structure of a new type of axial flux motor includes a silicon steel sheet body 1 and a plug-in 2. Four plug-ins 2 are annularly and equidistantly distributed on the side wall of the silicon steel sheet body 1 and are integrally formed with the silicon steel sheet body 1. A winding groove 3 is formed between two adjacent plug-ins 2 and the silicon steel sheet body 1;

[0019] An air groove 21 is provided on one side of the plug-in 2, and a plurality of horizontally through heat dissipation air ducts 22 are provided inside the plug-in 2.

[0020] As a further solution of the utility model: a shaft hole 11 is provided at the central position of the silicon steel sheet body 1, and the provided shaft hole 11 is used for connecting with a rotating shaft.

[0021] As a further solution of the utility model: both ends of the heat dissipation air duct 22 form an air inlet 221 and an air outlet 222. The air inlet 221 is located inside the air groove 21. During the rotation of the rotor, the air can be promoted to flow into the heat dissipation air duct 22 through the air groove 21, thereby dissipating heat from the rotor.

[0022] As a further solution of the utility model: a plurality of heat dissipation air ducts 22 are longitudinally and equidistantly distributed. The through direction of a single heat dissipation air duct 22 is horizontal. The provided heat dissipation air ducts 22 can improve its heat dissipation effect.

[0023] As a further solution of the utility model: the edge of the plug-in 2 is arc-shaped. The distance from one end of the plug-in 2 adjacent to the air groove 21 to the axis is farther than the distance from the other end to the axis. Therefore, when the rotor rotates, the air can be promoted to concentrate at the air groove 21.

[0024] The working principle of the utility model is as follows: when the rotor silicon steel sheet structure of the new axial flux motor is in use, it is connected with the rotating shaft through the shaft hole 11, and the coil is wound in the winding groove 3. When it rotates, the side of the plug-in 2 provided with the air groove 21 can rotate along the rotation direction, so that the air concentrates in the air groove 21, and then enters from the air inlet 221 of the heat dissipation air duct 22 located in the air groove 21, and is discharged from the air outlet 222 after passing through the heat dissipation air duct 22. In this process, the plug-in 2 and the silicon steel sheet body 1 are efficiently cooled.

[0025] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
