Análise computacional em elementos finitos das correntes harmônicas no motor de indução

The harmonic disturbances within the power electric system conveyed to the industrial sector cause problems in electrical equipment, resulting increasingly in preventative maintenance. Thus, computer simulations of electrical devices are performed utilising measured parameters for each equipment, enabling to predict future failures and their determining causes. Therefore, finite element method was used to simulate a three-phase induction motor in FEMM software from the data collected by a power analyzer device, and the most significant harmonic currents were chosen (3th order, 5th order and 7th order). The results obtained showed the behavior of the temperature and the magnetic field of the motor. Therefore, the simulations and resulting graphs help in the accurate analysis of the operation of this equipment, becoming a collaborative tool for the predictive maintenance area of the industrial sector.
