Converting mechanical energy to fluid form provides the "muscle" in a fluid-power system. The power source is the key element in a fluid-power system. In a pneumatic system the power source is an air ...

Engineers and designers commonly use electric motors to power hydraulic pumps. In some cases, the motor and pump are set up in a direct drive configuration. In others, they are connected using an ...

It might not look perfectly stable in the air just yet, but a company called Flowcopter is building the world’s first hydraulic drone that trades batteries and electric motors for pumps and gas ...

High vibration is a common problem for motors installed on top of vertical pumps. Its source can stem from a mechanical issue with the pump, motor, or coupling — or even hydraulic forces from the pump ...

March 2, 2009 Mechanical transmission of power using gears is very energy inefficient. The familiar automotive multi-speed gearbox and differential suffers from the friction losses that result in 20 – ...

A what you may ask? Well, a hybrid pickup, a dual powertrain vehicle that uses a gasoline engine, but instead of an electric motor and batteries, relies on a reservoir, accumulator and hydraulic pump ...
