“…K. Ravikumar Setty et al [15] presented a classification to the methods of RPD, which still adopted up to date. Although the majority of RPD methods, or studying the PMSM features, have a common point that they based on tracking the rotor magnetic saliency, such as in [16,17], they differ in field of application. This application field is related to speed of motor; standstill (halt), low or medium/high speed.…”

“…It may be worth to mention that the technique of pulse injections has been also used in driving systems of other motors rather than PMSM. For instance, X. Zhou et al [16] applied this technique on electromagnetic machine of doubly salient to predicate the rotor position through influencing the relation between the rotor sector and the minimum value of self-inductance.…”

Considerations around environmental pollution and green energy usage have led to environmentally-friendly machines being used in many industrial applications. Permanent magnet (PM) machines are the best solution to substitute the pollutant diesel-powered machines. In such machines, rotor position detection is crucial for safe startup operating. Meanwhile, encoderless controllers have become more reliable, over the years, in supporting the operation of PM machines. The key point, presented by this paper, is to introduce an improved positioning model to detect the rotor-position of interior permanent magnet synchronous machine at halt condition. To verify this objective, only two short duration pulses were injected into the stator windings. Then, the corresponding terminal voltage and current responses were measured and employed to create two memory address lines. Thereby, the memory cells, which contain the rotor position information, could be accessed. This detection model makes a significant improvement in rotor positioning detection of high resolution (1 degree) which represents lower value than most verified results in literature. The model was simulated and tested in a MATLAB/Simulink environment and shows an approximate accuracy 95%. Additionally, the statistical analysis was also employed to support the work outcomes.
