• This paper analyzes the sensorless control of AC machines based on the zero sequence voltage generated by the injection of a carrier signal voltage. The analysis focuses on rotor position estimation (tracking of rotor-position-dependent saliencies) but the methods discussed apply equally to flux position estimation (tracking of flux-dependent saliencies). Analysis of relevant aspects, like selection of the carrier signal frequency, measurement of the zero sequence carrier signal voltage, and decoupling of saturation-induced saliencies are included.
