This paper deals with induction machines analysis by finite-element analysis (FEA) for position sensorless control drives based on rotating voltage carrier injection. In details, it focuses the analysis of the supply conditions of the machine, both the high-frequency rotating voltage carrier and the fundamental frequency supply, for the optimal detection of the rotor slotting saliency effects. With...

This paper deals with modeling of induction machines and in particular of its slotting effects. It is a further improvement of former papers dealing with dynamic modelling of the induction machine including stator and rotor slotting effects. Starting from a previously developed space-vector dynamic model of the induction machine including rotor slotting effects, this work improves the analysis developing...
This paper presents a study concerning the vibrations generated by an induction motor drive controlled by field oriented control algorithm (FOC). The aim of the study is to identify suitable measurement points and analysis techniques in order to achieve information about vibration generated by an electric drive. Vibrations take origin both by the torque generated by the motor and the motor supply...
