A hydraulic motor is a rotary actuator that converts hydraulic or fluid energy into mechanical energy. They work in conjunction with hydraulic pumps that convert mechanical power into fluid or hydraulic power. The hydraulic motor provides force and provides motion to move the external load.
Today, the three most commonly used types of hydraulic motors are gears, blades and piston motors, which come in a variety of styles. In addition, there are some other less common variants, including gear motors or gear motors (tracks or balls).
The hydraulic motor can be either fixed or variable displacement and can be operated in both directions or in one direction. A fixed displacement motor drives the load at a constant speed while providing a constant input flow. Variable displacement motors can provide different flows by changing the displacement. The fixed displacement motor provides constant torque; the variable displacement design provides variable torque and speed.
The rotational and torsional forces of torque or motor force are expressed in inches-pounds or feet-pounds (Nm). There are three different types of torque. Separation torque is typically used to define the minimum torque required to start the motor at no load. This torque is based on the internal friction in the motor and describes the initial "separation force" required to start the motor. Operating torque produces sufficient torque to keep the motor or motor and load running. The starting torque is the minimum torque required to start the motor under load and is a combination of the energy required to overcome the load force and the internal friction of the motor. The ratio of actual torque to theoretical torque gives you the mechanical efficiency of your hydraulic motor.
Just look at the displacement of the hydraulic motor to determine its internal volume, so the amount of oil introduced into the motor at an angle of in.3 / rev or cc / rev when the output shaft makes one revolution is the volume of the motor. This can be calculated by increasing the volume of the motor chamber or by rotating the motor shaft one turn and manually collecting the oil and then taking measurements.
Flow is the amount of oil introduced into the motor per unit time at a constant output speed in gallons per minute (gpm) or liters per minute (lpm). It can be calculated by multiplying the motor displacement by the operating speed, or it can be calculated only by the flow meter. You can also make manual measurements by rotating the motor shaft one turn and manually collecting the fluid.
