The reasons why high-voltage motors produce electromagnetic sound may include the following aspects: Magnetic field changes: During the operation of a high-voltage motor, the current changes continuously in the windings, and the generated magnetic field will also change accordingly. This change in the magnetic field will cause mechanical vibrations in adjacent conductors or iron cores, producing sound.
Magnetic force: The current in the high-voltage motor will generate electromagnetic forces under the influence of the magnetic field. These forces will also cause vibration and resonance of the internal components of the motor, thereby producing sound.
Magnetic field leakage:In high-voltage motors, part of the magnetic field may leak into the surrounding environment and interact with conductors or objects, causing vibration and sound.
Poor design and manufacturing: The design and manufacturing levels of motors are different, and there may be problems such as substandard quality of parts or unreasonable structural design.
These factors will cause noise from the motor. To reduce the electromagnetic sound of high-voltage motors, some measures can be taken, such as adding sound insulation materials, increasing the structural strength of the motor, improving winding design, etc., to reduce the leakage of motor vibration and magnetic field, and ultimately reduce the generation of electromagnetic sound.
