  • Abstract
    Speed estimation is the most important issue in sensorless drives for induction motors. Estimation generally is based on the currents and voltages measurements; therefore, the correct speed estimation could be wrong due to deficiencies in the voltages and currents acquisition. This paper presents the effects in the speed estimation caused by the erroneous acquisition of signals in two speed observers. Experiments demonstrate that the performance of observers could be decrease with bad currents and voltages acquisition
