WHAT IS THE FUNCTION OF A HYDRAULIC MOTOR?
The main function of the motor is to convert hydraulic energy into mechanical work.

WHAT TYPES OF MOTORS ARE AVAILABLE?
A distinction is made between axial piston motors, radial piston motors, geared motors, vane motors and gerotor motors.
IN WHICH INDUSTRIES DO YOU FIND THEM?
Wherever a rotary actuator is required. Applications include plastic injection machines, sweepers, wheel drives of construction machinery, conveyor belt drives, tunnel boring machines and many more.
WHAT ARE THE CRITERIA FOR SELECTING MOTORS?
The choice of the type used depends on the required drive speed or torque requirements. It is also important to note whether the hydraulic motor should be used in the open or closed hydraulic circuit.
HOW TO ADJUST THE SPEED?
Some motors (e.g. axial piston motors and radial piston motors) are adjustable, where the speed of the motor can be adjusted directly. For others, the use of additional hydraulic valves is necessary (e.g. current control valves)
