Calculation methods for electromagnetically excited noise in induction motors

The development of low-noise motors will help to protect the environment and result in a competitive advantage. Designing low-noise electric motors means that it is necessary to predict the noise characteristics of the electric motor in the early conceptual phase. Customizing means that it is necessary to be able to estimate how the modifications affect the noise behavior of the motor. This paper presents two methods to calculate the electromagnetically excited noise of an electric motor, a numerical method for a more accurate result in the design process, and an analytical method for fast estimation in the customizing process.
