https://doi.org/10.1007/978-1-349-20967-5 latter attribute could be achieved by variable-displacement hydraulic pumps and/or motors. Multi-pump systems are described with an eye on wind turbine generator systems, with a detailed worked example to prove the feasibility and show the limitations on power of a variable-speed-ratio hydrostatic transmission system.

Empirical and Abstract Objects,In the mechanical engineering literature and practice it is usual to find . almost uniquely synonymous with .. This may be due to the fact that the majority of failures of mechanical components result from fatigue; bulk material and surface material fatigue. Design for fatigue endurance is based on either one of the following.

High Power/Torque-Density Devices,Mechanical power transmission and handling devices are evaluated according to their power density, or else their torque density if it is not the power that is the issue of primary concern. The combination of high power or torque density with good energy efficiency may collectively be termed high-performance density.
