This equals the fluid capacity required to turn the motor output shaft through one revolution. A hydraulic motor usually has a in.3 or cm3 per revolution displacement. Moreover, the hydraulic motor displacement is either fixed or variable. A fixed-displacement motor delivers continuous torque. Controlling the input flow amount varies the speed. A variable-displacement motor, on the other hand, offers variable torque and variable speed. Displacement variation alters the torque speed ratio to meet load requirements.
Torque output is conveyed in inch-pounds or foot-pounds. It measures the precise pressure drop across the motor.
The torque required to get a stationary load turning. More torque is required to start a load moving than to keep it moving. Running torque can refer to a motor’s load or to the motor. When it refers to a load, it indicates the torque required to keep the load turning.
This can refer to a motor’s load or to the motor itself. When it refers to a load, it specifies the torque needed to ensure the load keeps turning. When it refers to the motor, it identifies the actual torque that a motor can reach to keep a load turning. Running torque takes into account a motor’s inefficiency and is a percentage of its theoretical torque.
This refers to a hydraulic motor’s capacity to start a load. It indicates the amount of torque that a motor can reach to start a load turning. In some cases, this is significantly less than the motor’s running torque. In addition, starting torque can be displayed as a percentage of hypothetical torque. Starting torque for common gear, vane, and piston motors varies between 70% and 80% of hypothetical.
This is the ratio of actual torque delivered to theoretical torque.
This is the difference between minimum and maximum torque distributed at a certain pressure and during the hydraulic motor’s one revolution.
Is a function of motor displacement and the fluid volume transported to the motor.
Maximum motor speed
This is the motor’s maximum tolerated speed at a particular inlet pressure for a limited time without damage.
Minimum motor speed
This is the motor’s output shaft slowest, non-stop, uninterrupted rotational speed available.
Slippage is the motor leakage, or the fluid, that flows through the motor without accomplishing work.
