Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor noise control device. Background Art

[0002] Electromagnetic noise: This noise is caused by the mechanical force generated by the magnetized components in the alternating magnetic field. Mechanical noise: This noise originates from the mechanical parts of the motor, such as bearing wear, friction between the stator and the rotor, axial movement, rotor sweeping, loose or falling magnetic steel, etc. Wind resistance: The wind resistance noise in the motor mainly comes from the cooling fan being damaged or scraping the motor housing, or the motor being unstable. Electrically, for example, the carrier frequency of the inverter is set too low. Poor lubrication: Poor lubrication of the motor will increase the friction between the bearings and internal components, thereby generating noise. Installation problems: Damage to the coupling between the motor and the transmission machinery, or misalignment of the center lines of the motor and the transmission machinery during installation will cause excessive vibration and generate noise.

[0003] The problems listed above are basically noises generated inside the motor, which propagate from the inside to the outside. Utility Model Content
