This paper presents a technique that will calculate the absolute angular position of a permanent magnet (PM) rotor within a pole pair at standstill. The algorithm works with non-salient pole motors. By choosing an appropriate voltage pulse width and applying it to each phase winding, the stator currents will partially saturate the stator iron, enabling the algorithm to discern between a north pole and a south pole, and subsequently, the absolute position. The scheme is computationally simple
