ANPAM ENGINEERING offers an elbow type motor silencer employing aerodynamically designed long radius elbow baffles (CR = 0.5) for maximum attenuation and minimum pressure drop. Motor silencer connections are selected to exactly fit the motor fan inlet diameter and the internal silencer area is matched to the connection area so that there are no changes in air velocity. The fans on TEFC motors can often result in noise levels approaching 95 dBA, which is considered unacceptable in most industrial settings.
The noise reduction for this line of Motor Silencers is between 15 dBA and 35 dBA for standard sized. Higher noise reduction levels are available.
Motor Silencer accessories includes :
- Acoustic inlet covers
- Inlet screens
- Support legs
- Inspection panels
Noise generated from electric motor are mainly due to cooling air movement , bearing noise, magnetic noise due to cyclic variation of magnetic forces. Mounting the silencers on ventilation intake & outlet opening reduces the noise considerably. Larger capacity motors tend to emanate noise from the casing due to magnetic forces which may require acoustic hood.
ANPAM ENGINEERING designed, manufactured and delivered electric motor silencers in the capacity of range of 600 KW to 4500 KW.
