Hydraulic Motor

Ideal transformation between hydraulic and rotational domains

	Description
	The Hydraulic Motor component models an ideal single-vane rotary actuator. It transforms energy between the hydraulic and rotational domains.

	Equations
	$p = p_{A} - p_{B}$ $φ_{rel} = φ_{b} - φ_{a}$ $q = q_{A} = - q_{B} = displacement w$ $τ = - τ_{a} = τ_{b} = - displacement p$ $w = \frac{d φ_{rel}}{d t}$

Variables

Name	Units	Description	Modelica ID
$p$	$Pa$	Pressure drop from A to B	p
$q$	$\frac{m^{3}}{s}$	Flow rate into port A	q
$φ_{rel}$	$rad$	Relative rotation angle	phi_rel
$τ$	$N m$	Torque between flanges	tau
$w$	$\frac{rad}{s}$	Angular velocity of flange_b	w

Connections
