Constant Torque

Constant torque, not dependent on speed

 Description The Constant Torque component generates a constant torque, independent of angular velocity of flange. The Use Support Flange boolean parameter enables a support flange on the housing. When true (checked) the support flange must be connected in the drawing. When false the component is internally fixed to ground.
 Equations $\mathrm{\tau }={\mathrm{\tau }}_{\mathrm{constant}}=-{\mathrm{\tau }}_{\mathrm{flange}}$ $\mathbf{if}\mathrm{Use Support Flange}\mathbf{then}{\mathrm{\tau }}_{\mathrm{support}}=-\mathrm{\tau }$ $\mathrm{\phi }={\mathrm{\phi }}_{\mathrm{flange}}-\left\{\begin{array}{cc}{\mathrm{\phi }}_{\mathrm{support}}& \mathrm{Use Support}\\ 0& \mathrm{otherwise}\end{array}$
