In this paper, a novel extended permanent magnet synchronous motor model is presented that incorporates quadratic flux-current function to represent the polarity-dependent saliency. The proposed enables design of sensorless polarity detection algorithms required by initial position motors. novelty it integrates saliency into traditional machine and introduces new parameter, coefficient, specify...

2007〉 Recent developments in ultrasound (US) data processing have made it possible to develop new software. The latest generation of US workstations incorporate a central computer allowing very precise processing of the US image. This has made possible the reconstruction of images like three-dimensional US, second harmonic imaging for detecting contrast agents following intravenous injection, a...

Contrast ultrasound imaging has become a significant imaging technique for the last ten years. Physiological and pathological information are accessible thanks to microbubble injection and nonlinearity detection. To improve resolution and penetration, frequency modulated signals called chirps combined with compression filter have been utilized by radar technology. Recent studies applied the use...

In this article, a novel five-phase fractional-slot concentrated winding (FSCW) with 20-slot/22-pole is presented. It benefits not only the advantages of conventional FSCW but also weak space harmonics magnetomotive force (MMF). The allows eliminating first sub-order harmonic. new layout topology obtained by combination stator shift technique in slots special coupling windings (star-pentagon), ...
