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.

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 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.

What causes airborne noise in electric motors?

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. Noise damping materials can be applied to vibrating components to minimize airborne noise.

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 does my motor make a tapping noise?

Tapping noise caused by the thrust move of the rotor. Wind that occurs in a motor especially with a built-in cooling fan. Usually, the noise comes from multiple sources. To identify the root cause and specify the frequency, FFT analyzer is commonly used.
