Speed reducers are mechanical devices generally used for two purposes. The primary use is to multiply the amount of torque generated by an input power source to increase the amount of usable work.
Abstract: In this article, a second-order 3-D bandpass polarization-rotating surface (PRS) that can rotate vertically polarized incident waves by 90° and facilitate the output of horizontally ...
Abstract: In this article, a DD-4D double-layer orthogonal magnetic coupler with mutual inductance compensation is proposed for powering electrical equipment mounted on fixed sleeve during rotary ...
