Resumo

The present work aims to develop a Failure Mode Analysis table considering all possible parameters that may indicate a future failure in an inductive three-phase electric motor. The focus of the work remains on the motors of a metallurgical press factory. The types of analysis are temperature (using thermographic camera), vibration (using portable vibration meter), current and voltage (using multimeter). The construction of the FMEA table will be made by bibliographic research as well as by technical field survey, observing to what extent there is a limitation of scientific documentation for this subject. The purpose of the work is to reduce the number of plant production line stoppages due to failures in electric motors, as these have a major impact on equipment efficiency. The proposed FMEA table will be used as a procedure model for a maintenance plan and will be shown its implementation in practice, highlighting the actual positive result during the year of its application, with a reduction of more than half in problems in electric motors.
