Large-aperture Gasar porous metal material low vibration noise water-cooled motor

Abstract

The invention provides a large-aperture Gasar porous metal material low vibration noise water-cooled motor, which comprises an end cover and a stator, wherein a water cooling channel made of a Gasar porous metal material is formed between the end cover and the stator and surrounds the outside of the stator. Improvement is carried out on the structure of an existing water-cooled motor; and an existing spiral water cooling channel is replaced with a large-aperture Gasar porous metal material, and the porous metal material has good shock absorption and sound absorption characteristics and has a good thermal conduction characteristic, so that the processing problem of a traditional fluid hole is better solved. Therefore, the annular water cooling channel manufactured by the large-aperture porous metal material greatly absorbs vibration and noise generated by electromagnetic excitation force, the heat dissipation effect is strengthened and the application of the water-cooled motor is further improved.

technical field [0001] The invention belongs to the field of motor structure design, and in particular relates to a novel large-aperture porous metal material water-cooled motor with low vibration and noise. Background technique [0002] Most of the existing water-cooled motors use a spiral water channel between the motor casing and the stator as the water-cooling channel. Although compared with the air-cooled motor, the aerodynamic noise of the motor is greatly reduced, but the electromagnetic excitation force of the motor cannot be completely eliminated. For the impact of vibration and noise, the electromagnetic excitation force is the main source of vibration and noise of the motor. Moreover, the processing technology of the spiral water-cooled channel is relatively complicated, which greatly wastes materials, and the heat exchange capacity is relatively poor, so that the operating temperature of the motor cannot meet the required requirements. The existing water-cooled m...

[0002] Most of the existing water-cooled motors use a spiral water channel between the motor casing and the stator as the water-cooling channel. Although compared with the air-cooled motor, the aerodynamic noise of the motor is greatly reduced, but the electromagnetic excitation force of the motor cannot be completely eliminated. The impact on vibration and noise, electromagnetic excitation force is the main source of motor vibration and noise

Moreover, the processing technology of the spiral water-cooled channel is relatively complicated, which greatly wastes materials, and the heat exchange capacity is relatively poor, so that the operating temperature of the motor cannot meet the required requirements. The existing water-cooled motor structure cannot fully meet the needs of various industries. Requirements, resulting in poor operating results and reduced product demand
