This paper focuses on the calculation of noise and vibrations due to electromagnetic forces in rotating electrical machines in faulty conditions. The effects of a stator inter turn short circuit is analysed through an analytical model. Theoretical results give the radial forces and explain the reasons behind the noise and vibrations. They also show how inter-turn-short-circuit is responsible for additional low-mode forces, generating noise and vibrations increase. Experimental measurements are carried out to validate the theoretical results.
