RESUMO

This study motivation was finding a computer-based model that was able to foresee if the duty cycle applied in a single-phase induction motor implies or not in an overheating that can compromise the motor insulation. The solution presented here is based on finding a difference equation in which the system output (motor temperature at time k+1) is calculated as a linear combination of the input (motor temperature, RMS current and ambient temperature at time k). The Mean Square Method was applied to find the coefficients of this linear combination, resulting in the final computational model that represents the system. The computational results found with the proposed model reflect exactly the real system behaviour. This model is also useful to other applications in which a single-phase induction motor during intermittent periodic duty with starting is used.
