A stick-slip/inchworm hybrid rotary piezomotor based on a symmetric triangular driving mechanism, which can simultaneously achieve the benefits of both stick-slip and inchworm motors, was reported in this letter. It is based on the principle of stick-slip ...
The current framework of high penetration of intermittent energy sources requires variable-speed pumped hydro storage power plants (PHSPs) to provide grid support functions, which are, in this case, achieved through two technologies: doubly-fed induction m ...
Externally pressurized gas journal bearings (EPGJB) are widely adopted to support high speed rotors. This paper presents novel experimental benchmark test data which enables EPGJB model validation. Axial and circumferential pressure profile measurements ar ...
The rotating air-water ring, featuring a bubbly flow, in the vaneless gap of a reduced scale physical model of a pump-turbine operating in dewatered condition is investigated. High speed visualizations are performed together with pressure fluctuation measu ...
High power variable speed drives play a major role in many industrial applications. At the moment, these high power loads are supplied by the source (grid/generator) through the state-of-the-art MVAC power distribution network. The voltage levels, in these ...
