- Scope
- This part specifies the maximum sound power level for rotating electrical machines complying with GB 755, cooling method according to GB/T 1993 and protection classification according to GB/T 4942.1 and having the following characteristics: ——regular design for AC or DC; Except those specially improved to reduce the sound power level from the electrical, mechanical or acoustic aspects; - the rated output is from 1kW (or kVA) to 5500kW (or kVA); - the rotational speed does not exceed 3750r/min. AC motors powered by frequency converters are excluded, see IEC 60034-17. The purpose of this part is to specify the maximum sound power level LwA of the air noise emitted by the motor characterized by power, speed and load, in dB(A) for the motor of standard design; The test method and test conditions of the power level provide the assessment standard for whether the noise of the motor reaches the specified maximum sound power level. This standard does not provide corrections for the existence of pure tone characteristics. In some practical situations such as hearing protection, the sound pressure level at a certain distance from the motor will be required. However, this part is only concerned with the physical properties of noise sound power. The calculation of on-site sound pressure must know the size of the motor, operating conditions and the environment of the motor installation site. If necessary, the calculation data considering environmental factors can refer to classic acoustic textbooks.
