2. Change the following values as desired:
•
Animation Delay Factor — increase this number to slow the speed of animation of the
symbol blowing. This is not a real-time value.
•
On Current (Ion) — the current required to switch the LED on.
•
Reverse Breakdown Voltage — set as desired.
•
Maximum Rated Power (Watts) — the maximum power dissipation across the LED
allowed. If this value is exceeded during simulation, the inductor blows.
3. Click OK.
2.2.8 Rated DC Motor
The component is a universal model of an ideal DC motor which can be used to model the
behavior of a DC motor excited in parallel, in series or separately.
Note Refer to the Component Reference Guide for a more detailed discussion of DC motors.
 To adjust the component’s tolerances:
1. Double-click on the placed component and click the Value tab.
2. Change the following values as desired:
•
Animation Delay Factor — increase this number to slow the speed of animation of the
symbol blowing. This is not a real-time value.
•
Rated Armature Voltage (Van) — set as desired.
•
Maximum Armature Voltage — the maximum voltage across the armature allowed. If
this value is exceeded during simulation, the motor blows.
•
Rated Armature Current (Ian) — set as desired.
•
Maximum Armature Current — the maximum current through the armature allowed. If
this value is exceeded during simulation, the motor blows.
•
Rated Field Voltage (Vfn) — set as desired.
•
Maximum Field Voltage — the maximum field voltage allowed. If this value is
exceeded during simulation, the motor blows.
•
Armature Resistance (Ra) — set as desired.
•
Armature Inductance (La) — set as desired.
•
Field Resistance (Rf) — set as desired.
•
Field Inductance (Lf) — set as desired.
