A novel linear actuator for a tactile display is proposed, especially for Braille aimed for visually impaired people, and also for a new human haptics interface. The features of actuators for this use may be evaluated by output force, stroke, compactness, and so on. The proposed new actuator has better performance in terms of stroke, compactness, and output force compared with existing actuators....
Linear flux switching motor with segmented secondary (LFSMSS) is characterized by two kinds of windings, i.e. the DC field windings and AC armature windings, which are distributed alternately on the mover. LFSMSS is vulnerable to large force ripple. This paper investigates the influence of two design techniques (dummy slot and auxiliary tooth) on the force ripple of LFSMSS. In addition, the simulation...
The amorphous alloy transformer has less no-load current and loss, but the structure characteristics of the runway shape winding make it show greater vibration intensity and noise at the load condition. Based on the structure characteristics of the amorphous alloy transformer with runway shape winding, a leakage-stress-acoustic coupled calculation model is proposed to calculate the electromagnetic...
