Abstract
An original method of use of signals from the power convertor to determine the rotor position for self-regulation is proposed. These high-frequency (20 kHz) signals provide the carrier for the investigation and measurement of parameters of the phase model of the machine. Optimisation of synchronous demodulation of this carrier enables the influence of saturation on the value of these parameters to be reduced considerably, while increasing their relative variation with respect to the position of the rotor
