Torque Step

Constant torque, not dependent on speed Description The Torque Step component generates a torque step at a specified time. 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 $\mathrm{\tau }=-{\mathrm{\tau }}_{\mathrm{flange}}={\mathrm{\tau }}_{\mathrm{offset}}+\left\{\begin{array}{cc}0& t<{T}_{0}\\ {\mathrm{\tau }}_{\mathrm{step}}& \mathrm{otherwise}\end{array}$ $\mathbf{if}\mathrm{Use Support Flange}\mathbf{then}{\mathrm{\tau }}_{\mathrm{support}}=-\mathrm{\tau }$ $\mathrm{\phi }={\mathrm{\phi }}_{\mathrm{flange}}-\left\{\begin{array}{cc}{\mathrm{\phi }}_{\mathrm{support}}& \mathrm{Use Support}\\ 0& \mathrm{otherwise}\end{array}$
