The Speed Motor component needs a defined web speed on the input port v_web coming from a reference signal or an external control loop (e.g. a tension controller).  This component calculates internally the rotational speed of the motor from the defined web speed and a constant radius from the connected roller. Therefore, it is necessary to parameterize the roller diameter.  If the Speed Motor component is connected to a Unwind Drum or Wind Drum the diameter definition can be switched to the input signal port R_act.  The user has the possibility to connect it to a radius sensor or a radius calculation for the Unwind Drum or Wind Drum. The Speed Motor component has the capability to consider motor dynamic effects.  When the option Add simple motor dynamic is checked, a replacement dynamic as a second order system of a speed-controlled motor is used.

The Speed Motor component can be visualized in the 3-D Workspace and 3-D Playback Window to show the placement in the R2R web line and present the user-defined tension zones.  This is optional and supports the interpretation of a R2R web line. The position of the motor in the x-y plane is needed as well as the roller length, the motor length and the motor diameter.  The color can be also defined by the user.

These parameters are accessible when Show motor (visMotor) is checked (true).
