Abstract: This paper proposes and experimentally validates a method for driving flapping wings at large wing strokes and high frequencies with a DC motor, based on direct, elastic transmission. The DC ...

Abstract: Torque characteristics of brushless dc motors are studied in terms of the EMF and the feed currents for two feeding schemes: two-phase feeding and three-phase feeding. Various techniques for ...

It is made of a 1800W motor for the pressure power ranges of 2200-3500 psi and the flow rate ranges of 2.2-2.6 GPM, along with five spray tips for different cleaning tasks. The whole design of this ...

It's sad to say, but the golden age of compact cameras is pretty much over, thanks to the rise of smartphone cameras that are, in many cases, good enough for most people. Manufacturers seem to realize ...
