Defining VHDL-AMS DC Machine Values

  1. Open the VHDL-AMS DC machine Properties dialog box.
  2. On the Parameter Values tab, change InstanceName to DCM, la (Armature Inductance) to 9.5 mH, ke (Back EMF Constant) to 0.544 Wb, and j (Moment of Inertia) to 0.004 kgm2.
  3. On the Quantities tab, change ra (Armature Resistance) to 1.2 ohm. For the load (Load Torque) property, type LOAD.VAL in its Value field to “connect” it to the LOAD characteristic component.
  4. On the Property Displays tab add this property and visibility settings:

  5. Click OK to apply the changes.
  6. Open the Properties dialog box of Gain block N. Override the default INPUTValue by entering DCM.n to connect it to the VHDL-AMS motor speed property.
