Description

Technical Field

[0001] The utility model relates to a high-speed motor, in particular to a high-speed motor stator base structure for reducing high-frequency vibration. Background Art

[0002] The increase in motor speed significantly improves the power density of the motor itself, while also providing higher efficiency and power factor. These motors are widely used in aerospace, marine, and industrial applications. As motor speed increases, the operating frequency and speed gradually increase, generating greater mechanical and electromagnetic excitation forces. This leads to significant vibration and noise issues with high-speed motors, making them difficult to widely use in environments with strict vibration and noise control requirements. Summary of the Invention

[0003] The utility model proposes a high-speed motor stator base structure for reducing high-frequency vibration. The structure integrates a damping alloy material with a high-speed motor housing and reduces the vibration noise of the high-speed motor housing through the vibration absorption performance of the damping alloy material itself.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a high-speed motor stator base structure for reducing high-frequency vibration, comprising a stator cooling water tank, a damping metal rib plate, and an outer casing. The damping metal rib plate is made of high-damping copper alloy and is welded together with the stator cooling water tank and the outer casing to form a high-speed motor stator base structure that can absorb the vibration energy transmitted by the high-speed motor to the outside world and has a suppressive effect on the vibration noise of the high-speed motor.

[0005] Furthermore, the stator cooling water tank is composed of inner and outer cylinders, end plates and axial ribs, and water holes are staggeredly arranged on the axial ribs to form an axial "Z"-shaped cooling water channel.

[0006] Furthermore, the outer casing is formed by welding carbon steel with a high elastic modulus.

[0007] Furthermore, the damping metal rib is made of high-copper-based metal material.

[0008] The beneficial effect of the present invention is that by integrating the high-damping alloy material with the high-speed motor housing, the excellent vibration reduction performance of the high-damping material is utilized to absorb the vibration energy transmitted by the high-speed motor to the outside world, thereby having a certain inhibitory effect on the vibration noise of the high-speed motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a schematic diagram of the structure of a high-speed motor stator base for reducing high-frequency vibration according to the present invention. DETAILED DESCRIPTION

[0010] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0011] like Figure 1 As shown, an embodiment of the present invention provides a high-speed motor stator base structure for reducing high-frequency vibration, which is composed of an outer casing 1, a damping metal rib 2, and a stator cooling water tank 3. The outer casing 1 is welded with carbon steel, which makes the outer casing 1 have a high supporting stiffness and avoids structural deformation; the damping metal rib 2 is evenly distributed between the outer casing 1 and the stator cooling water tank 3, and is welded to the inner cylinder of the outer casing 1 and the outer cylinder of the cooling water tank 3. Cold welding is used to suppress the internal stress generated by deformation during welding, and the entire body is heat treated after welding. The present invention utilizes the excellent vibration reduction performance of high-damping alloy materials to weaken the vibration energy transmitted from the high-speed motor to the outer casing, thereby reducing the vibration noise of the high-speed motor.

[0012] The stator cooling water tank 3 consists of inner and outer cylinders, end plates, and axial ribs. The axial ribs are staggered with water holes to form an axial "Z"-shaped cooling water channel. The damping metal ribs 2 are made of a high-damping copper alloy and are cold-welded to the stator cooling water tank 3 and the outer casing 1. The high internal friction characteristics of the high-damping metal material absorb the high-frequency vibrations of the high-speed motor stator. The damping metal ribs 2 are made of a high-copper-based metal material. This alloy has a high internal friction value and excels in vibration reduction. It also has strong corrosion resistance and structural strength, making it suitable for the damping support structure of high-speed motors.
