Permanent magnet linear synchronous motor (PMLSM) has been widely used in various kinds of industrial applications due to its outstanding servo performance. However, the detent force is one of the major problems of PMLSM which brings about force ripple and mechanical vibration. The end effect detent force is the inherent defect of linear motors because of the length difference between primary and...
In the eddy current brakes, the magnetic field can be produced by excitation winding systems or by permanent magnets. According to the difference of flux sources, the eddy current brakes could be divided into three types: the electric excitation eddy current brakes, the permanent magnet eddy current brakes and the hybrid excitation eddy current brakes [1]-[2]. The hybrid excitation eddy current brakes...
We measured and analyzed the subthreshold degradation of the gate-all-around (GAA) silicon nanowire field-effect transistors with the length of 300/500 nm and the radius of 5 nm. An analytical model incorporating the effect of interface traps quantitatively explained the measured subthreshold swing degradation. A simple electrostatic argument showed that the GAA device had smaller degradation...
Due to the potential advantages of heavy load, high speed, and high precision, hundreds of parallel kinematic machines have been proposed. However, only a few of them have been practically applied, and one of the recently-developed parallel kinematic machines is the Exechon machine tool. It is based on the success of the Tricept, and its inventor has made tremendous efforts to promote its machining...
