The noise limits for each class are specified in tables and are based on the machine's rated power and speed.
The standard, titled "Rotating electrical machines – Part 9: Noise limits," is a cornerstone document in the field of electrical engineering and industrial environmental health. It provides the essential framework for measuring and limiting the airborne noise produced by standard rotating electrical machines, ranging from small 1 kW motors to massive 5,500 kW industrial generators. By establishing these unified limits, the standard ensures that manufacturers produce equipment that contributes to a safer, more sustainable acoustic environment. Core Objectives and Scope
IEC 60034-9 is not used in isolation. It is designed to be used in conjunction with other parts of the , which cover different aspects of rotating machine performance. These include:
