Vernier reluctance machine (VRM) with dc field coils in stator is a competitive rare-earth-free design for variable-speed industrial applications due to its robust structure and controllable excitation, while torque density relatively disadvantageous. To address this issue, article proposes new armature winding method VRM across two teeth. The key break the traditional principle based on flux m...

Thrust ripple and density greatly impact the performance of linear machine other actuators, causing positioning control precision, dynamic performance, efficiency issues. Generalized pole-pair combinations are difficult to satisfy both thrust for double salient reluctance machines. In this paper, a DC-Biased vernier (DCB-VRLM) is proposed solve abovementioned The key design reduce enhance with ...

Using as the stimulus a texture pattern of short lines, we compared positional acuity thresholds for an orientation-texture-defined (OTD) boundary and a luminance-defined (LD) boundary. Texture lines had different orientations but the same luminance on either side of the OTD boundary, and different luminances but the same orientation on either side of the LD boundary. For the LD boundary, both ...
