NOISE REDUCTION

Komel Centre offers lowering noise level of old-series induction motors. A lot of motors designed even in 60-ties or 70-ties are used in domestic power stations and thermal-power stations. At these time neither noise level no efficiency factor were we taken into consideration during designing of the motors.

Apart from reducing noise level, it is possible to encrease motor’s efficiency by reducing losses of cooling system (mechanical loses).

Motor type  SBDVdm 134t; 1000kW
after modernization 
(noise 83 dB(A)) 

Motor type SZJ 134s; 850kW
after modernization (noise 83,5 dB(A)) 

We have modernized several types of motors.
