Abstract :
This paper presents an initial pole position estimation method for low cost system which measures only the DC link current of inverters. The PWM patterns are restricted for this system in order to detect the phase currents. The saturation effect for the tested IPMSM is very weak. So, a method applicable to weak saturation effect machines is investigated.
