* The rated speed and torque refer to the output value under the rated flow and pressure.
* Continuous value refers to the maximum value that the displacement motor can work continuously.
* The intermittent value refers to the maximum value of the displacement motor working for 6 seconds in 1 minute.
* The peak value refers to the maximum value of the displacement motor working for 0.6 seconds in 1 minute.
