TORQUE ACTUATOR
Actuator: Select from the Torque Actuator drop down
menu the type of actuator the RSTC will control.
Actuator Inertia: Enter the rotor inertia of the brake or
clutch in the designated imperial or metric units. The choice
of units is determined by selecting the DISPLAY icon and
then selecting Imperial or Metric in the UNITS pane. Inertia
values for Nexen Brakes and Clutches can be found in the
Nexen catalog or website. For drive systems, enter the mo-
tor rotor, drive pulley, and shaft coupling inertias.
Refer to Appendix for inertia formulas and table of values.
Use an Actuator Inertia value of 1.0 in cases where the
actual value is not known.
