A Hydraulic cylinder is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notably in engineering vehicles.- Operation :...
Conceptually, a hydraulic motor should be interchangeable with a hydraulic pump
Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic.Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps, in which the displacement cannot be adjusted, or variable displacement pumps, which have a more...
because it performs the opposite function - much as the conceptual DC electric motor
An electric motor converts electrical energy into mechanical energy.Most electric motors operate through the interaction of magnetic fields and current-carrying conductors to generate force...
is interchangeable with a DC electrical generator
In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge to flow through an external electrical circuit. It is analogous to a water pump, which causes water to flow...
. However, most hydraulic pumps cannot be used as hydraulic motors because they cannot be backdrive
Backdriving is when a component is used in reverse to obtain its input from its output. This extends to many concepts and systems from thought based to practical mechanical applications.Not every system can be backdriven...
