Modelica Standard Library
The Linear Speed Dependent Torque component models a torque that is linearly dependent on the angular velocity of the flange. The Torque Direction parameter determines the sign of the torque when the velocity is reversed.
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.
