In the Project Manager, expand BusBarTransient / Maxwell3DDesign (Transient) / Excitations.

There are three bus bar objects: bus1, bus2, and bus3.

Expand each of the bus bar objects.

Note that a single-conductor input coil terminal and a single-conductor output coil terminal is defined for each.

Review the excitation for each of the bus bar objects, performing the following steps on each one:

1. Double-click the bus bar object.

   The Winding dialog opens.

2. Under Parameters, verify the following settings:

   1. Type is set to Current.

      Solid is selected.

   2. Current is set to the following expressions:

      • bus1 is set to 7070A*sin(2*pi*60*time)

      • bus2 is set to 7070A*sin(2*pi*60*time-120deg)

      • bus3 is set to 7070A*sin(2*pi*60*time-240deg)

      Each bus bar carries 7070A current at 60 Hz frequency, but each at a different phase.

3. Click Cancel to close the dialog.
