Abstract

A thermal model of a three-phase induction motor is validated by using fiber Bragg grating (FBG) temperature sensors. In the experimental setup, temperature, electrical and mechanical measurements were simultaneously obtained. Eight multiplexed FBG temperature sensors in a quasi-distributed configuration were used. Results from the simulation of the model presented a maximum difference of 0.75oC between the experimental values measured during the transient response of the motor and the simulated ones, while the steady state response converged to the measured experimental values. The instrumentation setup allowed the inclusion of the mechanical losses in the proposed thermal model, and this is the main contribution provided by this work.
