GB10069.3-88
Replaces GB2806-81
This standard specifies the A-weighted sound power of a rotating electrical machine when a single no-load steady-state operation Noise limits. This standard applies to various types of motors that comply with the requirements of GB755 and do not take any special noise reduction measures. Table 1 of this standard applies to AC and DC motors with a speed not exceeding 3750r/min and a power ranging from 1 to 5500kW. Table 2 and Table 3 of this standard apply to small-power asynchronous motors and single-phase series motors respectively. 2 Reference standards
GB10069.1 Rotating electrical machine noise determination method and limit noise engineering determination method GB10069.2 Rotating electrical machine noise determination method and limit noise simple determination method 3 Limit values ??
Table 1, 2 What is stipulated in and 3 is the noise limit of the A-weighted sound power level when a single motor is running in a steady state without load, without tolerance. The Ministry of Mechanical and Electronic Industry of the People's Republic of China approved the implementation on 1989-07-01 on 1988-08-31

3.1
If you need to assess the noise of the motor when running under load (such as series motor) , its limit value should be specified in the standard of the motor, and the corresponding measurement method should be proposed.
3.2 The assessment of motor noise should be based on the A-weighted sound power level, but the average sound pressure level value 1m away from the motor shell is allowed to be listed in the product sample.
4 Measurement methods
4.1 Motors assessed according to this standard shall be measured according to GB10069.1, and the measured results shall be used as the basis for assessment. 4.2 When the motor is measured according to GB10069.2, its limit value should be specified in the standard of the motor. Additional notes:
This standard is proposed and centralized by the National Technical Committee for Standardization of Rotating Electrical Machines. This standard is drafted by Shanghai Electrical Equipment Research Institute, Guangzhou Electrical Equipment Research Institute and Harbin Electrical Equipment Research Institute.
