This block is the model of a fixed displacement hydraulic motor.
The inputs to the block are:
The outputs are:
The motor drag torque is represented by the following equation:
DragTorque = Displ*(rkm*omg^1.4 + Ploss + (p1 + p2)*Cf)
where
Displ is the motor displacement
omg is the angular speed
p1 and p2 are the input and output pressure
rkm, Ploss and Cf are constant input data that shall be set to match the efficiency curve of the motor.
