Abstract
The purpose of this paper is to present speed characteristics of sensorless vector controlled two induction motor drives fed by a single inverter. The parameters of each motor, namely rotor speed and rotor flux, are estimated using flux and speed estimator to achieve speed sensor-less control. This paper presents experimental results as two motors added unbalanced load torques. The validity and effectiveness of control method is demonstrated through experiments.
