A detailed investigation of sensorless control of induction motor at zero and very low speed based on injection of a pulsating high frequency voltage signal is presented. A sensing technique is based on the secondary effect of magnetic spatial non-linearity caused by saturation of the stator laminations. Experimental and finite element results are presented.
