Motor Noise Solutions
2. For a motor that is running normally, if a short-circuit fault occurs in the stator or rotor windings or the squirrel cage rotor is broken, the motor will make a high and low buzzing sound. The fuselage also vibrates.
6 FAQs about [The energy storage motor makes a sound]
Why do electric motors make noise?
If the noise is due to something in the motor design (e.g., a manufacturing defect or anomaly), a solution may be impossible or impractical. With that in mind, let’s review the primary sources of noise in electric motors—magnetic, mechanical, and windage—as well as their causes and ways to reduce or eliminate them.
What are the different types of noise sources in electric motors?
Taking the previous components into consideration, three main types of noise sources can be distinguished in electric motors: Of electromagnetic origin. The electromagnetic noise in electric motors, sometimes called electrical noise, is primarily caused by the magnetic field in the air gap.
Why is my electric motor so loud?
When you notice unusual or loud noises coming from your electric motor, it’s important to understand the underlying causes to diagnose and fix the problem. Several factors can contribute to noisy electric motors, including loose stator cores, bearing issues, rubbing of internal components, and windage noise.
Why is windage noise a common problem in electric motors?
Windage noise is a common problem in electric motors, especially those operating at high speeds. It occurs due to turbulent airflow at obstructions near the rotating part of the motor. Identifying and addressing windage noise issues can significantly reduce the overall noise produced by the motor.
Why do geared motors make noise?
In geared motors, noise can be exhibited due to backlash, which is the space between gear teeth. Backlash noise is typically a consistent “hum” and does not indicate a malfunction. Damage or scratches on the gear teeth can also cause abnormal noise. Proper installation and inspection of gears can help minimize gearhead noise.
Why is airborne noise important in electric motors?
Maintaining proper airflow and preventing excessive heat buildup is crucial for the optimal performance and longevity of the electric motor. Airborne noise occurs when structural parts of the electric motor vibrate and generate sound waves. Rotational unbalance is a common source of airborne noise in electric motors.
