Small Hydraulic Motors
Small hydraulic motors are mechanisms that convert hydraulic energy into mechanical energy that can be used to power various machines. Small hydraulic motors have small stroke lengths, which is the distance that the piston moves inside the cylinder to achieve its extended state.
When the hydraulic fluid is pumped into the bottom chamber of a small hydraulic cylinder, the piston rod is pushed up, pushing the hydraulic fluid in the other chamber back into the reservoir. This process pressurizes the chamber and extends the piston to its full length, giving the hydraulic cylinder its ability to push. In small hydraulic motors, the piston's full measurement, or stroke length, may be less than an inch.
Although they retain all of the capabilities of larger hydraulic cylinders, small hydraulic motors are typically used in applications requiring high precision, as in military operations or robotics.
