Abstract: In the actual conditions of the energy and raw materials crisis, new efforts are made for increasing the performances of technical systems. In this framework, the reduction of the electrical motors vibrations used in hybrid and electrical vehicle is a way for increasing the lifetime and efficiency. The paper deals with an analysis of electrical machines faults in correlation with the vibration spectrum. Experimental tests on three types of induction motors with the speed of 1000 r.p.m., 1500 r.p.m. and 3000 r.p.m. with free suspension have been done. The vibration transducers of type accelerometers in combination with PULSE 12 platform have been used to measure the amplitudes of vibrations on the vertical, axial and perpendicular plan directions. Using the analysis in the frequency domain, the amplitudes of acceleration of the vibrations in the three directions in conformity with the regulation IEC 60034-14 have been established. The comparison with the literature data allowed identifying vibration sources, useful for the designers and manufacturers in diminishing the frequency of the induction machines defects.
