Rotational Constant Speed

Constant speed, not dependent on torque

 Description The Rotational Constant Speed (or Constant Speed) component generates a fixed 1-D rotational constant speed at the flange.
 Equations $w={w}_{\mathrm{fixed}}=\stackrel{.}{\mathrm{\phi }}$ $\mathrm{\tau }={\mathrm{\tau }}_{\mathrm{flange}}$ $\mathbf{if}\mathrm{Use Support Flange}\mathbf{then}{\mathrm{\tau }}_{\mathrm{support}}=-\mathrm{\tau }$ $\mathrm{\phi }={\mathrm{\phi }}_{\mathrm{flange}}-\left\{\begin{array}{cc}{\mathrm{\phi }}_{\mathrm{support}}& \mathrm{Use Support}\\ 0& \mathrm{otherwise}\end{array}$
