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 $p={p}_{A}-{p}_{B}$ ${\mathrm{\phi }}_{\mathrm{rel}}={\mathrm{\phi }}_{b}-{\mathrm{\phi }}_{a}$ $q={q}_{A}=-{q}_{B}=\mathrm{displacement}w$ $\mathrm{\tau }=-{\mathrm{\tau }}_{a}={\mathrm{\tau }}_{b}=-\mathrm{displacement}p$ $w=\frac{\mathrm{d}{\mathrm{\phi }}_{\mathrm{rel}}}{\mathrm{d}t}$
