A sensorless online temperature estimator is presented in this paper, which estimates the using a novel signal injection strategy. This allows to eliminate sensors machine, as well their faults, increasing system reliability. double dead-time DC injected adding controlled offset control drive through inverter. The proposed strategy eliminates effect of signal, an important drawback strategies f...
