An effective approach for optimizing the rotor contour variable reluctance (VR) resolver is presented. Using this approach, procedure divided into two parts: establishment of initial shape curve, and then computation optimization. In order to simplify process former, a function constructed. And latter carried out by Taguchi optimization method finite element (FEM). example 3–10 VR used present ...

This study explores attitudes towards and affecting online learning implementation. In recent years there has been greater acceptance of online learning by institutional decision-makers, as evidenced by higher levels of institutional involvement; nevertheless, the increase in faculty acceptance lags behind. This gap affects the widespread adoption of online learning. This paper proposes that fa...

Most advanced manufacturing processes require highspeed and high precision motion control for material transfer, packaging, assembly, and electrical wiring. Examples are surface mounting of electronic components, wire bonding of semiconductor chips, and assembly of watches and hard disks. To achieve precise motion control, most of these high-performance manufacturing machines use rotary d.c. or...
