Abstract

The forces generated by the magnetic field in a synchronous generator are studied as a source of vibration and noise. Finite Element Method (FEM) is used to sulve the magnetic field in the iron core and the air gap of the generator. The distribution of the radial force acting on the inner surface of the stator core is calculated using the classical Maxwell stress tensor method. The force distribution is then developed into a two dimensional Fourier series (space and time) and the spectral contents of the radial force istribution are analysed and compared to the spectra of the measured noise from the generator. The method is proved to be adequate for the prevention of noise components already in the design stage.
